Is the job running on the master? If not, what is the OS of the master?

This particular job was running on a Windows slave, master is Linux. The job is part of multi-configuration project that runs on both Linux and Windows slaves.

Got the same problem, the other way around. My master is Windows and the Linux slave is getting a bad PATH environment variable, where the master's JAVA_HOME/bin got injected:

PATH=D:\opt\jdk1.6.0_27/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games

I noticed the problem when I tried to launch a freestyle job on the slave, executing a shell script. Try the following script to exhibit the bad PATH:

#!/bin/bash
env

I have the same problem! On Windows slave and Jenkins installed on Linux O/S

Path=D:\Jenkins\tools\Custom_tool\NodeJS-0.9.9:/var/lib/jenkins/D: ...

Resolved issue in the version 0.3

Behavior may have been changed, but not actually fixed in 0.4.2. You now get

Path=C:\slave\tools\something;C:\slave\tools\something\bin;:C:\WINDOWS\system32;…

Note the : separating the path addition from the original path, causing the first entry in the original path to be unusable.

The functionality has been broken in https://github.com/jenkinsci/customtools-plugin/commit/1ed68b4a65642113f4a61da08aa5f2e4da5d5b4b (0.4.1). I'll fix the regression
