Compile goal does not inherit $JAVA_HOME thus cannot find javac

ISSUE

I've encountered an issue where the compile goal is failing with not being able to find javac. If I compile using play compile it succeeds. Here's the exception when using the Maven plugin to compile:

[INFO] Looking for 'play' in the System PATH [info] Loading project definition from /var/atlassian/data/bamboo/xml-data/build-dir/KIPA-TBT/mms/liveAdmin/project [info] Set current project to liveAdmin (in build file:/var/atlassian/data/bamboo/xml-data/build-dir/KIPA-TBT/mms/liveAdmin/) [info] Updating {file:/var/atlassian/data/bamboo/xml-data/build-dir/KIPA-TBT/mms/liveAdmin/}liveAdmin... [info] Done updating.

It feels like an environment issue where the compile goal is not inheriting $JAVA_HOME when using the plugin.

WORKAROUND:

I was able to determine the cause of the issue. For some reason when the compile goal invokes play to compile, commons exec does not inherit the environment setting for $JAVA_HOME. This is on CentOS Linux. This works fine on MacOS though.

The workaround was to modify the play script to set $JAVA_HOME and add $JAVA_HOME/bin to the $PATH.

Hi,

I've tried to propagate the environment to the launched process. So it inherits the PATH and JAVA_HOME properties. Can somebody test on Windows ?

Thanks.
