Kristian Rosenvold commented on MSOURCES-94:
--------------------------------------------

How much more memory does it actually require, and how many CPU cores do you have ?

> I managed to reproduce this locally by comparing the following two commands:
> {noformat}
> # Runs fine in under 10 seconds
> MAVEN_OPTS=-Xmx128m mvn -e org.apache.maven.plugins:maven-source-plugin:2.4:jar
> # Fails already after the third module with source code, after some 7 seconds
> MAVEN_OPTS=-Xmx128m mvn -e org.apache.maven.plugins:maven-source-plugin:3.0.0:jar
> {noformat}
> Our project is closed-source, but I verified the issue can also be reproduced on a large
Maven build such as the one of the [Jetty|https://github.com/eclipse/jetty.project] project.
