I have recently downloaded Maven and followed the instructions given on this this page. I already have ant installed on my machine.
Now, if I want to verify that Maven is installed perfectly or not it is giving me error that JAVA_HOME is not set correctly, but same works perfectly fine for ANT.
For Maven I tried :
1. open cmd
2. type mvn -version
3. Error appeared :
C:\Users\Admin>mvn -version
ERROR: JAVA_HOME is set to an invalid directory.
JAVA_HOME = "C:\Program Files\Java\jre7\bin"
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation
For ANT I tried and worked :
1. open cmd
2. type mvn -version
3. Apache Ant(TM) version 1.9.1 compiled on May 15 2013
I went to the directory to check that java.exe is actually there in that directory or not and it was there. I checked the environment variables they set fine. I restarted the system and checked again but same problem. Please let me know what am I missing.
JAVA_HOME should point to jdk directory and not to jre directory. Also JAVA_HOME should point to the home jdk directory and not to jdk/bin directory.
Assuming that you have JDK installed in your program files directory then you need to set the JAVA_HOME like this:
JAVA_HOME="C:\Program Files\Java\jdkxxx"
xxx is the jdk version
Follow this link to learn more about setting JAVA_HOME:
http://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/index.html
Do not include bin in your JAVA_HOME env variable
Follow the instruction in here.
JAVA_HOMEshould be like this
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_07
JAVA_HOME = C:\Program Files\Java\jdk(JDK version number)
Example: C:\Program Files\Java\jdk-10
And then restart you command prompt it works.
Just remember to add quotes into the path if you have a space in your path to java home.
C:\Program Files\java\javaxxx\ doesn't work
but
"C:\Program Files\java\javaxxx\" does.
The JAVA_HOME should point to the JDK home rather than the JRE home if you are going to be compiling stuff, likewise - I would try and install the JDK in a directory that doesn't include a space. Even if this is not your problem now, it can cause problems in the future!
You are pointing your JAVA_HOME to the JRE which is the Java Runtime Environment. The runtime environment doesn't have a java compiler in its bin folder.
You should download the JDK which is the Java Development Kit. Once you've installed that, you can see in your bin folder that there's a file called javac.exe. That's your compiler.
JAVA_HOME should point to jdk directory like in the image with new variable, like below
PATH should point to jdk bin like below
Run the below command in your terminal and restart it.
> set JAVA_HOME="C:\Program Files\Java\jdk-xx.xx"
xx.xx is the java version

I am trying to set up maven for my project and I am getting this error
"JAVA_HOME should point to a JDK not a JRE"
I know there are already similar question but it did not work. How can I point JAVA_HOME to JDK in windows. I am using IntelliJ IDEA
Control Panel -> System and Security -> System -> Advanced system settings -> Advanced -> Environment Variables -> New System Variable
I am going through the same process on Mac OSX. I installed the latest JDK, then installed Maven. Someone suggested I set the JAVA_HOME variable so I pointed it to the JDK installation folder. When running Maven mvn compile exec:java I received the same error NB: JAVA_HOME should point to a JDK not a JRE.
All I did was unset the JAVA_HOME variable and it worked.
do it thru cmd -
echo %JAVA_HOME%
set set JAVA_HOME=C:\Program Files\Java\jdk1.8.0
echo %JAVA_HOME%
I met the same problem. (Window 10 environment)
I solved it by deleting the JAVA_HOME="C:\Program Files\Java\jdk1.8.0_161\bin" in the User Variables instead of adding to the System Variables directly.
Then I test that editing JAVA_HOME="C:\Program Files\Java\jdk1.8.0_161\" worked too.
When I run "mvn -version" in command prompt window, it shows "Java home: C:\Program Files\Java\jdk1.8.0_161\jre".
In conclusion, I guess the JAVA_HOME shouldn't include bin directory.
I added JAVA_HOME path in user variable and omit the "/bin".
I tried every method given here but only this worked for me.
I have spent 3 hours for solving the error The JAVA_HOME environment variable is not defined correctly. This environment variable is needed to run this program NB: JAVA_HOME should point to a JDK not a JRE
Finally I got the solution. Please set the JAVA_HOME value by Browse Directory button/option. Try to find the jdk path. Ex: C:\Program Files\Java\jdk1.8.0_181
It will remove the semicolon issue. :D
My JAVA_HOME was set correctly but I solved this issue by running Command Prompt as Administrator
In Mac OS the hierarchy library > java > JavaVirtualMachines - (inside this folder there are different versions of jdk) select your desired version and inside jdk-version folder there is a contents folder inside contents you'll find "Home" folder
while declaring $JAVA_HOME you haVE TO GIVE THAT HOME PATH for example-
(normal shell commands)
open terminal type vi .bash_profile
(to open file name bash_profile)
press "i" to enable insert mode
give java home path as-
export JAVA_HOME=/Library/java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home
After editing press esc to exit editing mode
then :wq to quit and save
This will remove JAVA_HOME should point to a JDK not a JRE error
and also saves you from future errors
For mac OS, this worked for me... none of the above solutions
$ vim .bash_profile
export JAVA_HOME=$(/usr/libexec/java_home)
$ source .bash_profile
Be sure to use the correct path!
I mistakenly had written C:\Program Files\Java\. Changing it to C:\Program Files\Java\jdk\11.0.6\ fixed the issue.
In cmd I then checked for the version of maven with mvn -version.
Just as an addition to other answers
For macOS users, you may have a ~/.mavenrc file, and that is where mvn command looks for definition of JAVA_HOME first. So check there first and make sure the directory JAVA_HOME points to is correct in that file.
if You have
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE
Error
so do one thing ...type
C:>dir/x
and you will see the PROGRA~1 or May ~2
and After int Environment Variable Chang The JAVA_HOME Dir Like This
JAVA_HOME:- C:\PROGRA~1\Java\jdk1.8.0_144\
also Set In Path :-%JAVA_HOME%\bin;
And it Works
Make sure that you do NOT have a JRE path, if you have delete it.
Add JAVA_HOME in the System variable. Variable value: C:\Program Files\Java\jdk-10.0.2 (location of JDK without bin)
Add M2 in the System variable. Variable value: C:\dev\maven\apache-maven-3.5.4\bin (location of maven with bin)
Add M2_HOME in the System variable. Variable value: C:\dev\maven\apache-maven-3.5.4 (location of maven without bin)
Add %JAVA_HOME% and %M2% in Path System Variable or C:\Program Files\Java\jdk-10.0.2 and C:\dev\maven\apache-maven-3.5.4\bin --> For windows 10, just add the location. For other version, at the end of the Variable Value field add semicolon then the location Ex: ;%JAVA_HOME%;%M2%
I did not check if the addition or removal of bin changes the result but nonetheless this works for me.
In addition to sovas' response on how to add the JAVA_HOME variable, if it was working before and stopped working, ensure that the path still exists. I updated Java recently which deleted the old version, invalidating my JAVA_HOME environment variable.
This worked for me for Windows 10, Java 8_144.
If the path contains spaces, use the shortened path name. For example, C:\Progra~1\Java\jdk1.8.0_65
Under System Variables add below
JAVA_HOME = C:\Program Files\Java\jdk1.8.0_201
JDK_HOME = %JAVA_HOME%\bin
M2_HOME = C:\apache-maven-3.6.0
MAVEN_BIN = %M2_HOME%\bin
MAVEN_HOME = %M2_HOME%
Under path Add these
%M2_HOME%
%JDK_HOME%
you should only add this path to Manage Jenkins -> Global Tool Configuration -> JDK
for java 11
/usr/lib/jvm/java-11-openjdk-amd64
for java 8
/usr/lib/jvm/java-8-openjdk-amd64
And then use same in your jenkins jobs accordingly
In IntelliJ IDEA go to File>Project Structure>SDK>JDK home path.
Copy it and then go to
My Computer>Advanced Settings>Environment Variables
Change the JAVA_HOME path to what you have copied.
Then open new cmd, and try mvn -v
It worked for me !!!
Add JAVA_HOME = C:\Program Files\Java\jdk(version) in User variable, it works for me. For me, it doesn't work with bin and even if I create JAVA_HOME in system variable
just remove the semicolon at the end of JAVA_HOME variable's value.
set JAVA_HOME as C:\Program Files\Java\jdk1.8.0_171
It worked for me.
I had this issue but for Mac Os, I set the JAVA_HOME variable in the .bash_profile to be export JAVA_HOME=$(/usr/libexec/java_home) then save. After that ran source ~/.bash_profile finally mvn -version and it fixed the issue. Hope that helps
First, ensure that the Maven bin is in your Environmental Variable PATH entry.
If it is, make sure your entries aren't somehow out of order, and that JAVA_HOME is before Path in the list, or any entry that references %JAVA_HOME%. I was getting the same error when I was trying to check my maven version.
I have a few extra path variables that reference %JAVA_HOME%, or a different version of a JDK and Maven was mixed in between. I moved my Maven path entry below my %JAVA_HOME% one and now everything is working when I use Maven from cmd.
But it is Windows, so perhaps my just opening and closing the Environment Variables setting somehow made everything better.
Windows 10 Home for me:
I'm studying maven through a udemy course. First time environment variables were ok. I had on JAVA_HOME on SYSTEM VARIABLE like this:
D:\Install\Java\jdk-12.0.1;D:\Install\apache-maven-3.5.4-bin\apache-maven-3.5.4
After some days, don't know what's happened, I began to receive:
C:\Users\Franco>mvn -version
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE
After trying all above, I tried to delete jdk the entry on SYSTEM VARIABLES, and putting it on USER VARIABLES, so now I have:
JAVA_HOME on USER VARIABLES: D:\Install\Java\jdk-12.0.1
JAVA_HOME on SYSTEM VARIABLES: D:\Install\apache-maven-3.5.4-bin\apache-maven-3.5.4
now restarting CMD I have:
C:\Users\Franco>mvn -version
Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-17T20:33:14+02:00)

Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
In my case the error started showing up as Java version got updated. So JAVA_HOME path became invalid.
Please check
Location referred to in JAVA_HOME exists.
If it's like my case, update the value from the old path to the new path.
(A better fix would be to set java update such that it auto upgrades the JAVA_HOME reference.)
Even after trying this solution from sovas which is accepted if it does not work
RESTART intellij / CMD prompt instead of trying on the existing opened
i was trying the command from terminal under intellij but still getting same problem.
Do reopen cmd / INTELLIJ and the variable will get reloaded. It fixed the problem for me (ofcourse after correcting the Path to JDK not jre and removing the bin
I am trying to install Apache Ant on my system, while setting the path variable. I have jdk installed on my system. I set the ANT_HOME environment variable to where ant is located on the system, i.e, F:\apache-ant-1.9.6\, and the path variable to F:\apache-ant-1.9.6\bin.
But when I test if ANT is installed correctly by typing ant -version on cmd , I get this error:
Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre1.8.
0_25\lib\tools.jar
Apache Ant(TM) version 1.9.6 compiled on June 29 2015
While reading this answer, they say tools.jar in included in jdk and not jre. But I have correctly installed jdk, and set the environment variable correctly for that too.
When you actually go to the location specified by ant build it'll not have tools.jar.
The error is misleading and wrong. It is just because either JAVA_HOME is not defined or not set properly. Once it is done, error would get resolved.
I was also facing same issue but after research of an 1 hour I got a solution.
In system variable set your jdk path in starting.
Variable name: Path
Variable value: C:\ProgramFiles\Java\jdk1.8.0_45\bin;C:\Users\SESA401780\AppData\Local\Android\sdk\build-tools;C:\Users\SESA401780\AppData\Local\Android\sdk\tools;...
Enter Ok Ok ... and
Open new cmd
You are most likely missing the JAVA_HOME environment variable. It looks like the java.exe you are running from the command line is finding your JRE, not your JDK. Set JAVA_HOME to the location of your JDK, and move the bin directory of your JDK to be before the JRE in your PATH and try again, should work.
As the error message says:
Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre1.8.
0_25\lib\tools.jar
tools.jar is expected to be in C:\Program Files\Java\jre1.8,
but it's not there.
That path looks suspiciously like a JRE path,
not a JDK.
Make sure to set JAVA_HOME to the path of your JDK. Then it should work.
It seems that currently JAVA_HOME is pointing to the path of the JRE,
not the JDK.
I am trying to build my first android app using phonegap and for that i need jdk environment,node.js,ant.
And I am able to install jdk but for Apache ant I have tried many forum and tutorials for setting the path but not able to succeeded on this.
I set my varialbe like this....
Variable Name :- ANT_HOME
Variable Value:- C:\JAVA\ant\bin
Variable Name :- JAVA_HOME
Variable Value:- C:\Program Files\Java\jdk1.7.0_60\jre\bin\
But still i am getting "unalbe to locate tools.jar. Expected to find in C:\ProgramFiles\java\jre7\lib\tools.jar
BuildFile: build.xml doest not exists.
Build Failed.
PLEASE HELP ME OUT FROM THIS ANONYMOUS TROUBLES..
See HERE for Ant, jdk, tools.jar related instructions.
for Ant:
ANT_HOME set to C:\JAVA\ant and add ;%ANT_HOME%\bin to the PATH variable
for JDK:
JAVA_HOME set to "C:\Program Files\Java\jdk1.7.0_60\" (with the quotes if you have space(s) in your file path) and add ;%JAVA_HOME%\bin to your PATH variable.
close any command-prompt window(s) that were open prior to the changes above. Only command windows opened after the changes will have the updated environment variables.
JAVA_HOME should be the JDK installation directory (in your case C:\Program Files\Java\jdk1.7.0_60\. Then you add %JAVA_HOME%\bin to the path.
For java, see Update the PATH Environment Variable (Microsoft Windows).
You can follow a similar procedure to add ANT_HOME to your path. ANT_HOME should be C:\JAVA\ant and then you add %ANT_HOME%\bin to the path.
If echo %PATH% shows the correct values for both ant and java then you need to check your Cordova configuration as it appears your configuration is pointing to a Java Runtime Environment (JRE) instead of a Java Development Kit (JDK).
This can be done in 2 different ways:
1: From Command Prompt.
C:>set ANT_HOME=C:\Program Files\Ant Files\apache-ant-1.10.5
C:>set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_181
C:>set PATH=%ANT_HOME%\bin;%JAVA_HOME%\bin
C:> ant -version
Apache Ant(TM) version 1.10.5 compiled on July 10 2018
2: By setting environment variables.
Right click on This PC > Properties > Advanced system settings > Environment Variables > User variables > New > Variable name:**ANT_HOME & for **Variable value:**C:\Program Files\Ant Files\apache-ant-1.10.5 > **OK.
Now goto System variables to add bin path. System variables > double click on Path >New > C:\Program Files\Ant Files\apache-ant-1.10.5\bin >New >C:\Program Files\Java\jdk1.8.0_181\bin>OK.
Now lets check whether it is installed correctly or not.
goto Command Prompt > and type ant -version.
C:> ant -version
Apache Ant(TM) version 1.10.5 compiled on July 10 2018
That's it. Let me know if still getting any difficulties.
I am building a project in Java.
I have this error:
Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\lib\tools.jar
I have installed a JDK and the folder: C:\Program Files\Java\jre6\lib is in my system but the file tools.jar is not there.
Yes, you've downloaded and installed the Java Runtime Environment (JRE) instead of the Java Development Kit (JDK). The latter has the tools.jar, java.exe, javac.exe, etc.
In case this is still an issue for anyone, I have a bit of clarification on the previous answers. I was running into this same issue using ant with only a JDK installed. Although, the JDK installer gave me a directory structure like this:
Directory of C:\Program Files\Java
05/08/2012 09:43 AM <DIR> .
05/08/2012 09:43 AM <DIR> ..
05/08/2012 09:46 AM <DIR> jdk1.7.0_04
05/08/2012 09:19 AM <DIR> jre6
05/08/2012 09:44 AM <DIR> jre7
0 File(s) 0 bytes
and when I ran ant, it complained about not finding tools.jar under the jre7 subdirectory. It wasn't until I set "JAVA_HOME=C:\Program Files\Java\jdk1.7.0_04" that the error went away.
Install the Java SDK.
Add a System Environment Variable called JAVA_HOME with the value of JDK location.
Go to Control Panel\System and Security\System. Advanced System Settings, Environment Variables, System Variables, New... Example:
Variable Name:JAVA_HOME
Variable Value: C:\Program Files\Java\jdk1.7.0_21
Close/reopen your CMD window so that the new variable takes effect before attempting to re-run the ant command.
I had the same problem and copying C:\Program Files\Java\jdk1.6.0_26\lib\tools.jar to C:\Program Files\Java\jre6\lib\ext worked for me
If you have installed JDK 9.0.1 you will also have this problem as the tools.jar has been deprecated. See migration document.
Set your JAVA_HOME environmental variable to point to C:\Program Files\Java\jdk1.7.0_02.
If you are in Linux you can solve this by installing java on the system:
sudo apt-get install openjdk-7-jdk openjdk-7-jre
No, according to your directory structure, you have installed a JRE, not a JDK. There's a difference.
C:\Program Files\Java\jre6\lib
^^^^
It should be something like:
C:\Program Files\Java\jdk1.6.0_24
Don't spend too much time looking for tools.jar. If you get an error like that, don't be upset.
If you already have java JDK 1.5, go to your lib folder, and the tools.jar should be available there. Copy and paste it in your ant bin folder, then try to use the command ant -version.
You should see the expected result.
I had the same issue on a linux machine. I was quite frustrated at first, because I have installed both the JDK and JRE. I am using version 1.6, 1.7 and 1.8 simultaneously, and I have played a lot with the alternatives to have everything set properly.
The problem was quite stupid to solve, yet counter-intuitive. While I was using the correct JDK, I paid attention to the path of the tools jar maven complained about - it was expecting it to be
$JAVA_HOME\..\lib\tools.jar
The $JAVA_HOME variable pointed directly to my jdk folder (/usr/local/java which was also the correct $PATH entry and alternative sym link). It actually searches for the lib folder outside the java directory, because:
$JAVA_HOME\..\lib\tools.jar
will resolve to
/usr/local/lib/tools.jar
and that is not a valid location.
To solve this, the $JAVA_HOME variable should instead point to this location /usr/local/java/jre (assuming the JDK path is /usr/local/java) -- there is actually jre folder inside the JDK installation directory, that comes with each JDK. This new setup will cause maven to look at the JRE directory, that is part of the JDK:
$JAVA_HOME\..\lib\tools
which now resolves to
/usr/local/java/jre/../lib/tools.jar
and finally to
/usr/local/java/lib/tools.jar
which is where the tools.jar really resides.
So, even if you are indeed using the JDK instead of the JRE, the $JAVA_HOME has to point to the JRE. Remember, the OS alternative should still refer to the JDK.
go to your jdk path where you installed your java
For e.g In my PC JDK installed in the following path
"C:\Program Files\Java\jdk1.7.0_17\";
After go to the lib folder e.g "C:\Program Files\Java\jdk1.7.0_17\lib"
in the lib directory there is tool.jar file
Copy this file and past it in the lib forlder of jre7 directory
for e.g
"C:\Program Files\Java\jre7\lib"
You may face similar problem on Ubuntu:
Embedded error: tools.jar not found: /usr/lib/jvm/java-7-openjdk-amd64/jre/../lib/tools.jar
The problem is with JAVA_HOME that is not set properly.
So, on Ubuntu 14.04 x64 using Java8:
sudo apt-get install openjdk-8-jdk openjdk-8-jre
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
As many people mentioned, it looks like you are looking in your JRE instead of the JDK for the tools.jar file.
I would also like to mention that on recent versions of the JDK, there is no more tools.jar file. I downloaded the most recent JDK as of today (JDK version 12) and I could not find any tools.jar. I had to download JDK version 8 (1.8.0) here https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html to get the tools.jar file. I downloaded that version, took the tools.jar file and put it into my recent version's lib folder.
It's worth observing that tools.jar has been removed from the JDK since Java 9. https://docs.oracle.com/javase/9/migrate/toc.htm#JSMIG-GUID-055EA9F4-835E-463F-B9E1-9081B3D9E55D
If people are facing this issue compiling a Java program with JDK 9+, you may need to review the dependencies of your projects.
In my case, I was trying to compile a project using AspectJ and the Maven plugin org.codehaus.mojo:aspectj-maven-plugin:1.11. After searching online, I found an alternative that supports Java 9+: dev.aspectj:aspectj-maven-plugin:1.13.M3.
I had the same problem even after installing Java JDK and set JAVA_HOME to ..\jdk1.6.0_45\bin folder.
Ant is still trying to find tools.jar in C:\Program Files\Java\jre6\lib folder.
I've fixed it by adding JAVACMD environment variable and set path for it to java.exe in the jdk folder.
In my case it was C:\Program Files\Java\jdk1.6.0_45\bin\java.exe
it has been solved with me in windows os by setting the JAVA_HOME variable before running as follows:
set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_111
Make sure that both the %JAVA_HOME% and %JAVA_HOME%/bin paths are added to your PATH variable.
All the answers about copying tools.jar into the correct position is a poor idea at best.
Make sure that your IDE can find these jars the way it was designed and intended for.
In eclipse window> preferences>Java> Installed JRE, I pointed the directory to the jre directory in the jdk 1.7 and i worked file for me
e.g C:\Program Files\Java\jdk1.7.0_71\jre
I had my JDK_path (C:\Program Files\Java\jdk1.7.0_79) in my JAVA_HOME and also the JDK_path\bin in my PATH. But, still my ant was using the JRE instead of JDK.
The issue was I had C:\ProgramData\Oracle\Java\javapathbefore my JDK_path in PATH variable. I simply moved my JDK_path before the oracle one and the issue solved.
solving this problem I have simply copied the tools.jar file from C:\Program Files\Java\jre1.8.0_112\lib to C:\Program Files\Java\jdk1.8.0_112\lib so that I have two tools.jar files instead of one and problem disappeared.
Expected to find it in C:\Program Files\Java\jre6\lib\tools.jar
if you have installed jdk then
..Java/jdkx.x.x
folder must exist there so in stall it and give full path like
C:\Program Files\Java\jdk1.6.0\lib\tools.jar
Make sure that your classpath is set correctly and pointing to the correct version of the JDK that you have installed. Also, are you using Open JDK? I have had this issue before after I tried to move from open JDK to Suns JDK. This is an example of how that issue could be fixed.
maven-compiler-plugin use jdk ,not jre,
tools.jar is in C:\Program Files\Java\jdk1.6.0\lib\tools.jar
you must config project JRE System Libary with jdk,not jar. This is the simplest solution.
Right click on your ant file
Go to "Run as" then click on "Ant Build..."
Go to the "JRE" tab
Select a JDK and not a JRE
For me what's working: I downloaded an old version of Java 1.7
I actually set my JAVA_HOME from C:/program files X86/Java BUT after I installed the 1.7 version I had another Java in program files/Java. And at this moment I found the tools.jar here. Then I changed for this new path and it's working
I was also facing the same error.
This was removed after setting Java_Home path to C:\Program Files\Java\jdk1.8.0_121.
Please ensure bin is not included in the path and no slash is there after jdk1.8.0_121 after you have defined %JAVA_HOME%\bin in the system path variable.
If you're in a RHEL environment the package name containing tools.jar would end with "openjdk-devel".
This is the solution for Windows: in Computer > Advanced system settings > Advanced > Environment variables..., add this in System variables:
I have downloaded tools.jar and after that I copied it into path in error message.
C:\Program Files\Java\jdk-11.0.1\bin > paste here tools.jar
After that I have restarted Spring Tool Suit 4 and everything was working.
When I was trying to fix that problem I have made new environmental variable:
Control Panel / System / Advenced / Environmental variables / new
Name : JAVA_HOME
Value: C:\Program Files\Java\jdk-11.0.1
But I do not know is it necessary.
maybe you have updated the JREs in the OS, and the addition has added in the "path" of the environment variables an entry ".../Oracle/jer" that overwrites your JAVA_HOME.
try to remove it from the "path" by leaving JAVA_HOME.
i have Windows Vista and i'm trying to install maven and test it.
But i realised that i have a problem with JAVA and i have to solve first.
I do Start->Run->cmd
and i type in the command line,
C:\>mvn clean
i get the following error
ERROR: JAVA_HOME not found in your environment.
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation
So i say: Let's set the PATH for Java and i did:
Start->Control Panel->System->Advanced System Settings->Environment Variable->System Variables
Edit the PATH variable
C:\Program Files\Java\jdk1.6.0_32;C:\apache-maven-3.0.4\bin;
But then i get the same error when i do:
C:\>mvn clean
Then i typed in the cmd prompt:
C:\>java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b11)
and i realise that the Java version that is running is not located under the
"C:\Program Files\Java" directory
The only JDKs i have are:
jdk1.6.0_29
jdk1.6.0_32
Then i did Run->cmd
C:\>where java
C:\Windows\System32\java.exe
(Recently i downloaded IDE Eclipse and IDE IntelliJ and i don't know if these apps
come with the JDK).
Where can i find my JDK installation in Windows and set the path in environmental variables?
Go to
Start->Control Panel->System->Advanced System Settings->Environment Variable->user variables
Click on new button
give the
variable name : JAVA_HOME
variable value: C:\Program Files\Java\jdk1.6.0_32
in that way you setup your java home and try
Also make sure to take new command prompt after you did any changes in environment variables
Eclipse comes bundled with a JDK, I believe you need a seperate one to run maven.
My environment variables look like this.
JAVA_HOME = C:\Program Files\Java\jdk1.6.0_33
Path = (tacked on the end) ;%JAVA_HOME%\bin;C:\Program Files\Spring Tools Suite\apache-maven-3.0.3\bin
This is all working but as you can see I got maven by installing STS. It's just an eclipse distro which comes bundled with maven (among other things).
You can also set java home from command line prompt. But this will be valid only in your session and it will be gone once you close your command line session.
Hope it helps.
set JAVA_HOME=C:\Program Files\Java\jdk1.6.0_33
Late to the game, but run this in an elevated command prompt:
setx /M JAVA_HOME "path_to_Java"
This will set the path for your machine and not the user. Remove /M to have it set just for the user account.
The guide at SS64 (and setx /?) say you're supposed to have the /M switch at the end, but my personal experience is that it doesn't always work at the end.
