Install a master node and slave node.
Invoke a task on the slave with Mercurial "repository caching" enabled.
I get this output:

$ /usr/local/bin/hg clone --noupdate <repository> C:\Users\Gili\.jenkins\hgcache\37CF2BD3BA29C01DED84F6376395B553ABB57E93-vtlr

I see two problems with this output:

The "hgcache" path being defined relative to the master node's root directory instead of the root directory of the slave. There is no way this will work.
ProcessBuilder complains it can't run "/usr/local/bin/hg" because "The system cannot find the file specified". I believe it finds "hg" because I've confirmed the path exists and the log clearly shows "hg clone" working. Please modify the code to output more verbose information (what is the working directory and full path associated with ProcessBuilder?)
