When I am trying to debug my code then I am getting the following error:

Maven uses JAVA_HOME to access Java's location on the machine. In Your situation You point it to JRE not JDK. Set properly JAVA_HOME environment variable and it will work.
If You want to have different location/version used for Maven only You can edit mvn.bat file with something like this.
set JAVA_HOME=<path_to_other_jdk>
Your JAVA_HOME path is not set. You need to set it as C:\Program Files\Java\jdk <version>
Everything is said in the exception:
Unable to locate the Javac Compiler in: C:\Program Files (x86)\Java\jre6..\lib\tools.jar
Your maven task is trying to "compile" something, but can't find the Java compiler (JDK=Java Development Kit).
Please ensure you are using JDK 1.4 or above and not a JRE.
Instead it finds a JRE=Java Runtime Environment (which is used for running java programs, not compiling them).
you can change the location of your Java installation by setting the JAVA_HOME environment variable
You need to have a valid JDK version installed and your JAVA_HOME environment variable must point to this JDK folder.
Yeah Thanks for the clue..
Everyone is correct.
In my JDK version tools.jar was not available thats why I was getting this problem its not finding tools.jar, While JAVA_HOME varible is configured correctly.
Need to focus on only Tools.jar so that installed again java version (i am using java 6)
Now come on project--> go thru the build path and Make sure----
click on
installed jre
edit
jre home =C:\Program Files (x86)\Java\jdk1.6.0_25
give path accordingly for which Your OS is compatible

I'm trying to run an AEM project. I successfully added it from cmd and now I'm trying to run it from InteliJ but I'm getting error.
Im trying with mvn clean install -PautoInstallPackage because I have running instance and want to build and package the whole project and deploy AEM with it.

This is the full code i get in my debugger. I have tried to remove and reinstall java once also added the environment variable JAVA_HOME properly still this issue is not leaving me from last 2 days . Getting frustrated due to it. Please Help
Judging from the error you are seeing seems like Gradle is set to point at your JRE standalone installation and not the JDK...
Judging also from your post, seems like you are running Windows.
So, first of, make sure you have the JDK installed:
You can search for it in your file system yourself (which is most likely located under
C:\Program Files\Java\ directory).
Open a CLI (ie Command Line Interface, or command prompt) and type javac -version and tell us how it responds.
Open a CLI and type where javac and tell us how it responds. It should print the location of your javac.exe executable (which will be under the JDK install directory, which in turn will let us know where is your JDK installed).
If you don't have the JDK installed, make sure you do, by downloading+installing it. For example you can get Oracle's JDKs from here. Make sure you select the desired JDK and not JRE. For example for version 8 (which is the version of Java I can see you are using) you can navigate here.
Then, make sure Gradle points to the JDK installation and not the standalone JRE.
To do this, I am not an expert on it, but if Gradle is using JAVA_HOME enviroment variable, make sure this value points to your JDK and not the JRE. You can open a CLI and type
echo %JAVA_HOME% and tell us how it responds. If it shows a JRE installation, try changing this enviroment variable to the JDK installation. Also don't forget to put %JAVA_HOME%\bin in your PATH enviroment variable if it is not already (more on this later in this post).
By the way, which IDE are you using (for example Android Studio, Eclipse, etc...)?
Aside from everything I am suggesting you here to tell us, you can try the following answers in another similar post which may help:
How to configure Gradle to run from JDK.
How to set JAVA_HOME properly to point to the JDK.
How to override default java.home Gradle property.
Note that JAVA_HOME is an enviroment variable which should point to the JDK, while the java.home is a Gradle property which should point to the JRE.
Try the possible solutions above, and don't forget to let us know your observations and how each CLI command responds.
I've been searching all over for a solution to this. I have Jenkins running on Linux server. I created a Jenkins job and deployed my code on the Jenkins machine. Everything works great. I added a Windows slave machine and moved my job to the windows machine. I continue to get this error:
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] No compiler is provided in this environment. Perhaps you are running
on a JRE rather than a JDK?
I ensured the JAVA_HOME was set.
I also set the tools location for the windows slave:
C:\Program Files (x86)\Java\jre1.8.0_92\bin
Still the same error when it tries to compile the code on the Windows slave machine.
I was wondering is this a maven issue, where I need to define in the POM.xml the location of the JDK?
Solution is:
1) In the job you are running on the slave machine you need to set the JDK you want to build with.
2) Configure the slave server, add the JDK8 in the Tools section
I upgraded from Java7 to Java8
JAVA_HOME is C:\Program Files (x86)\Java\jre8
I am trying to run maven install on a plugin and I get the following error
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project IcrMappingReport: Compilation failure
[ERROR] Unable to locate the Javac Compiler in:
[ERROR] C:\Program Files (x86)\Java\jre8\..\lib\tools.jar
In all the projects I updated the JRE System Library to jre8 and also in
Windows -> Preferences -> Java -> Installed JREs to C:\Program Files (x86)\Java\jre8
Can anyone tell me the problem?
You need the Java8 JDK not the JRE.
JDK stands for Java Development Kit, (includes Compiler)
JRE stands for Java Runtime Environment, so it's just for running Java Programs.
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
Compiler is included in JDK, not JRE.
You need a JDK in order to compile java source code.
I am trying to compile a HTML project, from this youtube video. But when I am running that HTML external tool, it gives me an error:
Configuration on demand is an incubating feature.

I was searching on internet, but I didn't find a solution which worked for me. Can anybody help me?
hello sorry for my English, while I do not use windows, but I think you have to install the Java JDK, look for this if you do not have it, I think he had to do something like this:
1 Right-click the My Computer icon on your desktop and select Properties.
2 Click the Advanced tab.
3 Click the Environment Variables button.
4 Under System Variables, click New.
5 Enter the variable name as JAVA_HOME.
;C:\Program Files\Java\YOUR VERSION JAVA JDK \src.zip
It actually doesnt work. If i set the loc to : C:\Program Files\Java\jre7 It gives an error which i show in the first post.
If i set the loc to : C:\Program Files\Java\jre1.8.0_25\bin
ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jre1.8.0_25\bin
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
I tried to C:\Program Files\Java\jre1.8.0_25\libs but the same.
BTW: I dont have JDK, i have only JRE.. I downloaded an JDK from java˘s web, installed it, and in my Java folder appeared only the JRE.
