When executing the build on a slave the output is:

FATAL: C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe doesn't exist
Finished: FAILURE

although the MSBuild.exe is in the given directory on the slave.

Plugin should only check on the build slave – we run a Linux master and Windows slaves, so any check on the master is doomed to failure.

Patch attached that fixes this issue. I altered the check so that it uses a FilePath object to check for the existance of the msbuild executable. The channel from the launcher references the node doing the build so the check gets performed on the slave.

Patch verified with hudson 388.

Can we get this committed already?

It seems that kdsweeney hasn't been active and the patch for this bug has already been submitted. It just needs to be committed. This is a major bug preventing anyone using a Linux master or a Windows master with a different version of .Net from using the plugin. Do you have the time to deal with this or can you assign it to someone who does?

Fixed JENKINS-4121

I tested msbuild-plugin version 1.4 and can confirm that the issue is resolved in that release.

Thanks for pulling the patch in Gregory.
