Maven error - invalid source release: 8

I have a new, empty module which I'm trying to configure to use Maven (there are no dependencies yet).

I have Maven configured for targeting Java 8 and while this does correctly set the module language settings to 1.8, the Maven compilation still fails.


Note that the logging seems to indicate that it's using Java 7 for running Maven.


I have already set the Maven Runner to use my 1.8 SDK. Am I missing something else, or is this a bug?


Compilation works fine if I switch the pom file to target 1.7.

Thanks!
