[jira] [Commented] (MCOMPILER-534) Broken command line generated on Java 8 when maven.compiler.release is set

["Michael Osipov (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MCOMPILER-534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17715478#comment-17715478 ] 

Michael Osipov commented on MCOMPILER-534:
------------------------------------------

You can't do this. You provide is moot since you have set the property already globally. It is passed directly to the plugin. Either set the property within the profile or set a literal value.
