Benson Margulies reopened MCOMPILER-120: ---------------------------------------- I'm reopening this because the 'fix' has a pretty major problem: no message os printed explaining why the compilation fails. Adding -e and -X do not lead to the actual message arriving. {noformat} [INFO] Changes detected - recompiling the module! [INFO] Compiling 179 source files to /Users/benson/x/gcoref/core/target/classes [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 4.000 s [INFO] Finished at: 2015-01-26T13:50:23-05:00 [INFO] Final Memory: 30M/705M [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.2:compile (default-compile) on project res-core: Compilation failure -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

The reason is that in compileInProcess the exit code > from javac is only considered if there are no messages. In the case of > treating warnings as errors, there will be messages but no errors so the > intention of the build failure is lost. -- This message was sent by Atlassian JIRA (v6.1.6#6162)
