Hi,

I'm not sure if this is a gitblit issues, or somewhere else in the stack involved.

I've recently migrated a few repositories onto gitblit - 1.8.0 - and I also use maven / JGitFlow

When I do a release like this:

mvn jgitflow:release-start jgitflow:release-finish -DuseReleaseProfile=false -DreleaseVersion=1.2.6 -DdevelopmentVersion=1.2.7-SNAPSHOT -DaltDeploymentRepository=vadev::default::https://....

I end up with a failure at the very end -

... error occurred during unpacking on the remote end: error Missing commit <commit hash> ...

The end result, is that it doesn't push the master branch updates, nor does it clean up the release branches. Everything else happens properly - the tag is made / pushed - all of my artifacts successfully make it onto nexus, etc.

Another oddity with this - the commit that it says is missing - is actually present when I go browse gitblit.

After the failure, I can simply go to eclipse, and push the master branch, and delete the remote release branch - and there are no further errors - everything works properly - as if the release had completely correctly.

I saw your note in the FAQ about the unpacker error, but it doesn't feel like quite the same failure.

This release pattern works for me against github.

I'm waiting for my sysadmin to wake up and check the logs on the server, to see if anything interesting got reported there... but thought I'd post the question in the meantime, and see if this has been seen before.

Awesome tool / project, by the way.

Thanks,

Dan

Hi Dan,

I have most often seen the unpacker error with a missing tree message. But it also manifests as missing delta base and I see no reason why it can't manifest as missing commit.

Since you are testing JGit with three different tools (JGitFlow, Eclipse, & Gitblit) and Eclipse worked it wouldn't surprise me if the EGit team has worked-around the known unpacker error in JGit until a suitable fix is applied.

I'll look at those closer - thanks for the links. Here are the logs from the server:
