The feature org.eclipse.equinox.p2.user.ui has a lower version in the current 3.7.x stream build than in the Indigo release: Indigo: 2.1.1.v20110526-6-Bg9JXOePwKUTU7X0teV1RtDu-e M20110810-0800: 2.1.1.R37x_v20110726-1115-6-Bg9JXOePwMUSW9lu0QQ4a2EEi3 With 'R' < 'v', the Indigo version is considered newer. When updating multiple Eclipse platform/Equinox features from Indigo to 3.7.x stream, the "Equinox p2 Provisioning for IDEs" feature is not updated. This typically makes the update fail because of conflicting versions. The qualifier change when branching off for maintenance is recommended in [1], but I can't find anything mentioning the problem of decreasing versions when changing the qualifier. In fact, if everyone really followed the recommendations (i.e. added 100 for the first change in the master branch after a maintenance branch-off), the qualifier should be changed so that it increases when starting maintenance. Still, all this would require working build avoidance, and this doesn't seem to be in place... So we just fix it by increasing the one feature version by 0.0.1 in the maintenance branch and 0.0.100 in master? [1] http://wiki.eclipse.org/Version_Numbering
Fixed in master: http://git.eclipse.org/c/equinox/rt.equinox.p2.git/commit/?id=85a0848fc362e15afdc15a37a7a65aa0c56af49e Fixed in 3.7.x: http://git.eclipse.org/c/equinox/rt.equinox.p2.git/commit/?h=R3_7_maintenance&id=753ac03a20395b36083c4c580b25ffb2e7b09cdc
I can confirm that the problem has been fixed for org.eclipse.equinox.p2.user.ui in M20110831-1030. However the same problem occurs for the three other p2 features: org.eclipse.equinox.p2.core.feature org.eclipse.equinox.p2.extras.feature org.eclipse.equinox.p2.rcp.feature With 'R' < 'v', these features have a lower version number in M20110831-1030 than in Indigo.
Kim, shouldn't these errors be picked up as part of the releng tests when the build is being run when we run the comparator against 3.7?
I thought I had updated the builder to compare against 3.7 but in fact it still compares against 3.6.2. I've opened bug 356822 for this issue and will run a test build for 3.7.x in case there are any problems.
Thanks Kim. I've updated the core, extras, and rcp features to 1.0.1 in the maintenance build and will keep an eye on the test results once the comparator has been updated.

I've incremented the p2.discovery and compendium.sdk features.
(In reply to comment #8) > I've incremented the p2.discovery and compendium.sdk features. Thanks DJ, +1 to fixing these last issues.
