missing tools.jar for scala gradlew build

[DirkRichter]

When i try to build the project v0.16.2 using 'gradlew build', i get the error:

Execution failed for task ':compileScala'.

Could not find tools.jar

See the complete build log: build.txt

It's probably a problem of your JAVA_HOME environment variable.

[DirkRichter]

nope: JAVA_HOME is set. What else could it be? A missing dependency?
Here is the log:
C:\dev\githup\robot-plugin>echo %JAVA_HOME%
C:\Program Files (x86)\Java\jre1.8.0_111

You should set your JDK, not the JRE as JAVA_HOME

[DirkRichter]

thanks.

Now using JDK the build succeed with some failing tests:
