While importing projects into eclipse i have this error:
Cannot find System Java Compiler. Ensure that you have installed a JDK (not just a JRE) and configured your JAVA_HOME system variable to point to the according directory. Could not execute build using Gradle distribution 'http://services.gradle.org/distributions/gradle-1.11-all.zip'.
As I have checked i need to set JAVA_HOME (i have the JDK on my computer), but i dont have a clue how to do that.
I had lots of similar problems and I think that the best solution is to specify JDK location manually. In order to do it:
Add two files to project root folder
gradle.properties:
org.gradle.java.home=C:/Program Files/Java/jdk1.7.0_03
and local.properties:
org.gradle.java.home=C:/Program Files/Java/jdk1.7.0_03
You should change org.gradle.java.home value to JDK path in your system. If you will have the same problem with android SDK add sdk.dir=/Users/alonzilberman/Android/adt-bundle-mac-x86_64-20130917/sdk to your local.properties.
After adding files refresh gradle build.
I got the same message while trying to build a project in Android Studio. After hours of research, trying different versions of JDK (from 8 to 6) I found this answer that fixed my problem: https://discuss.gradle.org/t/mac-gradle-issues-with-finding-using-jdk-7-the-usual-answers-to-this-question-arent-working-expert-required/2553/24
The reason was that the AUSKey package installed a tools.jar in /Library/Java/Extensions directory that derailed Gradle looking for the compiler. Removing that file fixed the problem and I can now build in Android Studio.
Create a new system variable called JAVA_HOME and add
C:\Program Files\Java\jdk1.8.0_25
It's because your environment variable isn't pointing to your jdk folder. Don't point it to your bin folder.
