[jgit-dev] JGit checkout of multiple tags fails with "Could not rename f

[Sascha Vogt <sascha.vogt@xxxxxxxxx>]

Hi all,

since a few days I'm banging my head against a (JGit) wall ;) Maybe
somebody here understands my issue.

I'm trying to checkout a few tags one after another (to archive some
source code), but switching from one tag to another gives a strange
"Could not rename file" JGitInternalException.

Basically what I want to do (in cmd line commands):
1. git clone <url>
2. git checkout -b <tag-1> <tag-1>
3. git checkout -b <tag-2> <tag-2>

On cmd line this works, in JGit I'm using the following commands:

Git.cloneRepository()
           .setURI(url)
           .setCredentialsProvider(getCredentialsProvider())
           .setDirectory(tmpDir)
           .call();

git.checkout()
    .setName("tag-1")
    .setCreateBranch(true)
    .setForce(true)
    .call();

git.checkout()
    .setName("tag-2")
    .setCreateBranch(true)
    .setForce(true)
    .call();

The error I'm getting (full stack at the end of the mail):
org.eclipse.jgit.api.errors.JGitInternalException: Could not rename file
D:\dev\tmp\unit-test\git\base\common\locator\._pom.xml6206658336832583616.tmp
to D:\dev\tmp\unit-test\git\base\common\locator\pom.xml

Strange thing: It doesn't fail always, but around 90-95% of the time.
Also I'm on Windows as the path above suggests ;) TortoiseGit is
installed but I have disabled the TGitCache process. Also no explorer
was open on the used directory.

I also did git status commands in between checkouts -> no changed files.

I did also insert a git.clean().setCleanDirectories(true).call() and
git.reset().setRef("HEAD").setMode(ResetType.HARD).call() between
checkouts, no differences.

I tried JGit 2.3.1, 3.2, 3.4.1 and 3.5.0-rc1, also no differences.

When I check the state after such a failed checkout of tag-2 I'm seeing:

"git status":
HEAD detached at ef1edf8
nothing to commit, working directory clean

"git branch" gives:
* (detached from ef1edf8)
  tag-1
  tag-2
  master

Has anybody any idea? I've no idea where to search next.

Greetings
