Can you check the status of git server with compatibility to 3.7.1?

[lextiz]

git-server is compatible with JGit 3.7.1.

hi @skabashnyuk,
The jump from JGit 3.7.1 to 4.0 is minimal compared to the jump from 2.3 to 3.7.1, with no effects on the APIs we use (mostly stability and performance improvements). Maybe we should just skip 3.7.1 right to 4.0? Eclipse Mars is bundles with 4.0 which means it is stable for production use.

I need to make sure git server functionality remain the same. I'm ok with 4.0 also.
We can start with this one

<dependency>
    <groupId>org.eclipse.jgit</groupId>
    <artifactId>org.eclipse.jgit</artifactId>
    <version>4.0.1.201506240215-r</version>
</dependency>

If you sure it's 100% source code compatible with che code.
When I will organize integration testing here. And when I will aprove this change
WDYT?

[tareksha]

Seems logical to me. I'll update the pull request to contain 4.0.1.
Do you have a rough time estimate for when will this go through in case of positive results?

[skabashnyuk]

No ETA for this time.

[skabashnyuk]

Passed my local test. If nightly test will fail I'll rollback this changes.
