[ https://issues.jboss.org/browse/JBIDE-21821?page=com.atlassian.jira.plugi... ] Nick Boldt commented on JBIDE-21821: ------------------------------------ To further clarify why egit views disappear after installing JBT 4.3.0.Final: when you install JBoss Tools EGit Integration (or possibly something else in JBT?) it pulls in org.eclipse.egit.ui.importer_4.0.0 which depends on org.eclipse.jgit_4.0, available from our associateSite-liked default "last stable" target plaform [1]. (4.1 is NOT preinstalled in Eclipse JEE bundle, and is not on the Mars site, so p2 can't find a newer version to install 4.1 instead.) [1] http://download.jboss.org/jbosstools/targetplatforms/jbosstoolstarget/mars/ So even if you've already got jgit 4.1 installed, you break your installation (egit stops working) because: {code} Bundle was not resolved because of a uses contraint violation. org.osgi.service.resolver.ResolutionException: Uses constraint violation. Unable to resolve resource org.eclipse.egit.ui [osgi.identity; osgi.identity="org.eclipse.egit.ui"; type="osgi.bundle"; version:Version="4.1.1.201511131810-r"; singleton:="true"] because it is exposed to package 'org.eclipse.jgit.transport' from resources org.eclipse.jgit [osgi.identity; osgi.identity="org.eclipse.jgit"; type="osgi.bundle"; version:Version="4.1.1.201511131810-r"] and org.eclipse.jgit [osgi.identity; osgi.identity="org.eclipse.jgit"; type="osgi.bundle"; version:Version="4.0.3.201509231615-r"] via two dependency chains.{code} So by removing access to jgit 4.0 in the TP, we eliminate the second dependency chain. My workaround above was to uninstall org.jboss.tools.openshift.egit.integration.feature ("JBoss Tools EGit Integration") from the 4.3.1.CR1 site and reinstall it from a site which includes the 4.1 version of org.eclipse.egit.ui.importer. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
