Installing Red Hat JBoss Developer Studio 9.0.0GA into a fresh Eclipse 4.5.2 (for Eclipse Committers) causes Egit to break.
- Install Eclipse 4.5.2
- In the Marketplace, search for "jboss developer studio"
- You get a single result: Red Hat JBoss Developer Studio 9.0.0 GA
- Install it
- Observe: the EGit views and preferences are missing
- Observe: you get messages in the Eclipse error log concerning a dependency version incompatibility
JBT 4.3.0.Final / JBDS 9.0.0.GA target platforms include org.eclipse.egit.importer.ui 220.127.116.11506090130-r (Mars.1 version), which installs jgit 18.104.22.168509231615-r (Mars.1 version); this breaks egit 4.1.1 views when installed into Mars.2, because Mars.2 site does not include org.eclipse.egit.ui.importer 22.214.171.124511131810-r, and you confuse egit when you have both jgit 4.0 and 4.1 installed, disabling views and preferences.
Solution proposed is to add org.eclipse.egit.ui.importer 126.96.36.199511131810-r to the composite site from which JBT 4.3.0.Final and JBDS 9.0.0.GA are installed, so that when org.eclipse.egit.ui.importer is installed, p2 can select the 4.1.1 version instead of the 4.0.0 version.
I would want to pull a mirror of http://download.eclipse.org/egit/updates-4.1.1/ onto download.jboss.org if we're cool with this solution.
