---------------------------------------

             Summary: Do not ignore toolchains to set -source and -target
                 Key: MCOMPILER-254
                 URL: https://issues.apache.org/jira/browse/MCOMPILER-254
             Project: Maven Compiler Plugin
          Issue Type: Improvement
    Affects Versions: 3.3, 3.2, 3.1
         Environment: Maven 3.3
            Reporter: Robert Schaft


Maven 3.3 enhanced the support for toolchains (by allowing toolchains.xml in the ${M2}/conf/ directory). The compiler plugin already uses the toolchains to determine the jdk home.

Unfortunately, it still requires setting -source and -target. So I still have 3 places to set the jdk version of my source code.

The following pom.xml snippet currently sets the jdk home to 1.8, but uses 1.5 flags for source and target.

I simply request that the snippet sets source and target to 1.8 (or doesn't set them at all when a toolchain is used).
