Could not find or load main class org.eclipse.jgit.pgm.Main

Hi there,

Here is one I have:

optimus(sbt2)> git status

git.sbt at the root of the project that contains:

useJGit

plugins.sbt that contains:

addSbtPlugin("com.typesafe.sbt" % "sbt-git" % "0.8.5")

build.sbt that contains:

enablePlugins(GitBranchPrompt)

@joan38 sorry for the late response. I can't reproduce your issue. Could you create a stub project that reproduces the problem and share it with us? Thanks!

[aradke]

I have the same issue on a windows 7 machine and sbt-0.13.11. I can reproduce the issue with a stub empty project with the only file the project\plugins.sbt which has the line:

addSbtPlugin("com.typesafe.sbt" % "sbt-git" % "0.8.5")

Then after running sbt and set useJGit and git status, I get the same error:

Error: Could not find or load main class org.eclipse.jgit.pgm.Main
[info]
java.lang.RuntimeException: Nonzero exit code (1) running JGit.

I have since been able to fix this issue by replacing the following line in JGitRunner.scala

    val cp = cl.getURLs map (_.getFile) mkString ":"

to

     val cp = cl.getURLs map (_.getFile.replaceFirst("^/([A-Z]):","$1:")) mkString sys.props("path.separator")

There were two issues:

1. Windows paths from Url have some strange leading '/'
2. Windows path separators use ";" instead of ":"

[dwijnand]

We should setup AppVeyor, reproduce a failing test case and then make that change.

Anyone interested in sbt-git on Windows, feel free to send a PR.

[kwalcock]

This code might work better for Windows and maybe everything else as well:

val cp = cl.getURLs map (url => new File(url.getFile).getCanonicalPath) mkString File.pathSeparator
