Robert Scholte closed MANTRUN-220.
----------------------------------
Assignee: Robert Scholte
Resolution: Not A Problem
The problem is in mvn_jdk5.bat : Maven 3.6.2 requires at least Java 7 to run
with.
I don't see any specific things here that requires ant, so I'd suggest to drop
the maven-antrun-plugin and switch to dedicated maven-plugins.

> Previously used is java6+maven2.2.1, you need to make some projects compile
