Looks like the latest upgrade to Eclipse (3.4-2 -> 3.4-3) did something odd: after the upgrade, Eclipse started ignoring my old configuration (in ~/.eclipse/org.eclipse.platform_3.4.0_1473617060) and started using a new one it created (in ~/.eclipse/org.eclipse.platform_3.4.0_1543616141). With older versions of Eclipse I might not have cared. But with the new 3.4 version, which now uses the new P2 plugin system - which stores all your installed plugins into the configuration directory, instead of a directory of your choosing - the net result was that all my plugins were suddenly no longer installed after the upgrade. Anyone know why it decided to insist on a new config directory? Could it be because the Eclipse executable was moved from /opt/eclipse to /usr/share/eclipse? If that's the case then hopefully this won't be an issue in the future. I hope so, as it'd be a pain to have to deal with this on every minor and major upgrade to the package. Granted the workaround is pretty easy (copy the contents of the old config dir to the new one), but it's still a pain. Thanks, DR
