Should have been more clear –
We use a junction so actual files and directories are on the desired drives and paths. When setting up a node we identify the “default” CWD w/ active drive – this is either replaced with a junction or the subdirectories are made as junctions. These junctions also include setting up various tools to directories without spaces in the name e.g. CWD\tools\junction-to-jdk -> c:\program files\Java\jdk-x.y.z\ -Jason From: jenkinsci-users@googlegroups.com <jenkinsci-users@googlegroups.com> On Behalf Of Jérôme Godbout Sent: Friday, November 27, 2020 11:34 AM To: jenkinsci-users@googlegroups.com Subject: RE: Java install for Windows agent?

Ho right, mine was into c:\JenkinsSlave Starting agent process: cd "c:\JenkinsSlave" && C:\Java\1_8_0_261\/bin/java -jar remoting.jar -workDir c:\JenkinsSlave -jar-cache c:\JenkinsSlave/remoting/jarCache make me wonder why it need to change the directory before running since the working directory is already pass as an argument, the remoting.jar should change the current working directory by itself in a cross platform way. This seem like someone got lazy into the remoting.jar and put that awkward cwd needs in front. Should maybe have a flag to move to cwd to workDir --CwdFromWorkDir if not all use case need that. That would avoid all that mess upfront and make it easier to have cross platform behavior.

I fixed it by putting 'E: && ' in the remote command prefix box. Perhaps there is a better way ...
