What version of Mylyn is included in Mars M6? I can’t figure this out by looking at the aggregation files since Mylyn is one of those projects that points to a URL with varying content. I tried the latest build present at that URL (3.15.0.v20150323-1913), but I consistently get the following error during install.
An error occurred while collecting items to be installed
session context was:(profile="" phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action="">
Multiple problems occurred while downloading.
