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.

> Trying to use 3.8.1 (or select older versions) with JDK 8 result in {{--release}} being passed to {{{}javac{}}}, which does not like that.

> 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.
