             Summary: Disable m2e indexing by default
                 Key: JBDS-2904
                 URL: https://issues.jboss.org/browse/JBDS-2904
             Project: Developer Studio (JBoss Developer Studio)
          Issue Type: Enhancement
      Security Level: Public (Everyone can see)
          Components: maven, p2-product
    Affects Versions: 7.1.0.GA
            Reporter: Fred Bricon
            Assignee: Fred Bricon


By default, m2e (<= 1.4) downloads remote nexus indexes on startup.
- expanding the nexus index is very CPU intensive
- each workspace eats up at least 500MB once m2e has started.

It can be disabled in the workspace preferences but ideally, we should disable it by default for all JBDS installation on new workspaces.

Stock Eclipse Java EE Kepler has this setting turned off by default (see plugins\org.eclipse.epp.package.jee_*\plugin_customization.ini)

m2e 1.5.0 (M6+) will turn it off by default (https://bugs.eclipse.org/bugs/show_bug.cgi?id=404417), so JBDS 8.0 get the new setting for free.

We should just add org.eclipse.m2e.core/eclipse.m2.updateIndexes=false
to com.jboss.devstudio.core\plugin_customization.ini for JBDS 7.1.1.
