Olivier Lamy commented on MCOMPILER-477:
----------------------------------------
we need more informations regarding your pom.
are you using such:
{quote}<configuration>
<release>8</release>
</configuration>
{quote}
if so you must remove it as it pass the flag to the compiler and it is not
supported before jdk 9.
> maven-compiler-plugin > 3.5.1 fail on JDK 8

> Might be related to https://issues.apache.org/jira/browse/MJAVADOC-703 which
> is pretty much the same but for the maven-javadoc-plugin starting past a
> certain version. I tested them independently of each other, though.
