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)
Maven home: D:\Install\apache-maven-3.5.4-bin\apache-maven-3.5.4\bin\..
Java version: 12.0.1, vendor: Oracle Corporation, runtime: D:\Install\Java\jdk-12.0.1
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 have JAVA_HOME set in the necessary system environments, but the VScode plugin IBM Z Open Editor gives me this error:
Your "JAVA_HOME" environment variable does not specify a valid file path. Please verify that (1) The path does not end in "/bin/java". (2) The path points to a 64-Bit Java. (3) The path points to the correct location in the file system.
(From what I can see) I have all three of these points the error is pointing to. Any help is appreciated.
Type java --version in Command Prompt to check if you installed JDK11 or recent version, also 64-Bit. If not, reinstall the correct one:
Reference:
Installing a Java Development Kit (JDK)
To Install the JDK Software and Set JAVA_HOME on a Windows System
The settings about JAVA_HOME in VS Code should be:
"java.home": "C:\\Users\\...\\AppData\\Local\\Programs\\AdoptOpenJDK",
Which you can also configure it by opening Command Palette(Ctrl+Shift+P) then choosing the option: Java: Configure Java Runtime
The installed JDK which is JDK11 or recent version should be displayed in the list and you can choose the one you wanted, which is equal to manually setting java.home in Settings.json.
If you can't see the installed jdk in the list, turn to the referenced link to check if JAVA_HOME in Environment Variables is set correctly.
The system cannot find the path specified.
JAVA HOME is not set correctly.
I am getting the following error when I try to run web server in Eclipse:
The system cannot find the path specified.
JAVA HOME is not set correctly.
But checking my env variables they look correct:
echo %JAVA_HOME%
C:\Program Files (x86)\Java\jdk1.8.0_101
echo %PATH%

Is there something else I'm missing?
Check for system environment variables and user environment variables... seems like eclipse is taking variables from different environment..
If problem persist then set the JAVA_HOME in eclipse to tell eclipse explicitly where java is installed in the system. To set JAVA_HOME in eclispe few options given below.
To set JAVA_HOME in eclipse navigate to windows menu -> preferences -> Add runtime variables
OR
Navigate to Run menu -> External Tools configurations -> Navigate to environment tab -> Add JAVA_HOME variable and it's path as it's value to set environment variable in eclipse.
actually the path/classpath/any setting is on "Administrator" privilege and will NOT be accessed if eclipse is started directly.
right click on eclipse.exe and select "Run As Administrator".
hope it works
This seems a bug in Eclipse to me.
Eclipse comes with Java built in already. It's somewhere deep down in Eclipse. Users have no idea where it is.
Only Eclipse itself can set JAVA_HOME properly.
Installing your own Java and setting JAVA_HOME to point to there seems a bad idea, introducing potential conflicts between the built-in java version and JAVA_HOME contents
I have both Java 8 and 7 installed. I set the JAVA_HOME variable to the path to the java 7 jdk bin folder, and it is included in PATH. I double checked everything.
However, when I type Java -version, I get Java 8.
I am using Windows 7.
Add JAVA_HOME\bin to the beginning of your path. If you´re on windows:
set PATH=%JAVA_HOME%\bin;%PATH%
or
set PATH=C:\Program Files\Java\jdk1.7.0_79\bin;%PATH%
Your OS will pick the java which appear first in the system environment variable called PATH. So set the Java7 home first in the path variable like this
set PATH=%JAVA_HOME%\bin;%PATH%
This is applicable for the terminal you have opened.
If you want to set this permanently follow the instructions
Right-click the My Computer icon on.
your desktop and select Properties.
Click the Advanced tab. Click the.
Environment Variables button. ...
Enter the variable name as JAVA_HOME.
Enter the variable value as the installation path for the Java Development Kit.
Click OK.
I found the solution. I moved JAVA_HOME variable earlier in the PATH and it works now.
When typing a command on your shell (both windows and linux), the executable is searched in folders specified in your PATH from left to right, i.e. if PATH=folder1;folder2;folder3, your shell will search for the command in the folder1, then in folder2, and finally in folder3.
I suppose your PATH looks like PATH=jdk8_bin_folder;windows_stuff;jdk7_bin_folder;other_stuff. So, when typing java, your shell will find the jdk8 before the jdk7.
A common solution is (as already says) to use the JAVA_HOME variable to store the jdk folder, and use it in your PATH :)
You have to do two things
Remove Java.exe, javaw.exe and javac.exe from system32folder
if C:\ProgramData\Oracle\Java\javapath exists in path of the system environment variable then remove. when installing new version of java, installer set it automatically
Now set JAVA_HOME and set path(%JAVA_HOME%\bin)
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.
