java.io.FileNotFoundException when checking out a branch [message #491174]

Hello,

when I try to checkout a branch using the following code ...

private void loadBranch(String refName) throws IOException {
Commit commit = repo.mapCommit(refName);
Tree tree = commit.getTree();
GitIndex index = repo.getIndex();
new WorkDirCheckout(repo, repo.getWorkDir(), index, tree).checkout();
index.write();
repo.writeSymref(Constants.HEAD, refName);
}

.... I sometimes get a FileNotFoundException with a stack trace like the
following:

java.io.FileNotFoundException:
D:\Stanley\SHK\AMOR\runtime-EclipseApplication\voldemort\src \java\voldemort\serialization\VoldemortOperation.java

This error occurs often but by chance. Everytime the affected file is
another and I can't figure out what the reason may be.

Missing parent directory? Maybe WorkDirCheckout isn't always creating
the leading path like it should?

I don't know, I'm not very familiar with WorkDirCheckout... I haven't
looked at or called that code in years.

No, the parent directory (repo.getWorkDir()) is created everytime similar.
Or do you think about another parent?

I was thinking about the parent directory of the file...

>>> java.io.FileNotFoundException:
>>> D:\Stanley\SHK\AMOR\runtime-EclipseApplication\voldemort\src \java\voldemort\serialization\VoldemortOperation.java
>>> (Zugriff verweigert) --> Access denied

So does

D:\Stanley\SHK\AMOR\runtime-EclipseApplication\voldemort\src \java\voldemort\serialization\

exist when this fails like this? Is the directory maybe not writable?

OK, for any reason today everthing works like it should.
Maybe this is because I restarted eclipse or my system.
I didn't change anything at all. strange...Windows ^^
Nevertheless thank you for your replies, nice to have a bit support :)

Another question:
Is there any further documentation of JGit/EGit except the small
tutorial and the javadoc in the source?
And Is there an update site where I can get the org.eclipse.jgit plugins
(not the spearce-packages -> beacause of the dependencies)?

No. We want to move the tutorial from code.google.com to the Eclipse
Wiki under the EGit directory, and we'd certainly appreciate help from
folks who understand a bit of JGit to help us document it further.
Jonas did a nice job with the bit he did write, but docs are far down on
everyone's priority list. :-\

Not yet. Actually there is a Maven depot at code.google.com/p/egit/
which now also has an org.eclipse.jgit namespace. But I wouldn't
encourage using it just yet...

We're hoping to release a JGit/EGit 0.6.0-M1 near the end of the month,
and have the build artifacts available through the Eclipse download site
and mirrors. Those would be built against the JARs from Eclipse Orbit.
