Description Mickael Istria CLA 2019-05-14 02:41:49 EDT 
When downloading sources, the download source job can take too much RAM, sometimes leading to OutOfMemory.

This seems caused by similar issue as bug 515668 : too many projects are loaded in the same Maven context, with a lot of duplication, and this can make memory consumption explode. Since we don't need all projects at the same time for this operation (unlike a refresh than will reevaluate dependencies between projects), we can simply process them one by one.

Merged.
