[jira] [Closed] (MCOMPILER-248) Missing compiler in configuration
creates cryptic error
[ https://issues.apache.org/jira/browse/MCOMPILER-248?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Scholte closed MCOMPILER-248.
------------------------------------
Resolution: Incomplete
Assignee: Robert Scholte
Missing the code which caused this issue, so cannot reproduce it. Try maven-compiler-plugin 3.6 once released, since it has improved error message parsing.
