[JENKINS-5084] WORKSPACE env variable is incorrect for matrix project on windows slaves

WORKSPACE environment variable should have a windows format on windows platform.

The synthax is \workspace\\label/windows if (windows is the node alias)

This is for me a major drawback as workspace env variable is important.

To reproduce:

I create a matrix project "test_matrix" executed on 2 nodes (windows & solaris) for each platform define an env ARCH var=sunos/winnt

-------- configure ant task and a build.xml to execute a windows or unix script according platform.

















Launch compilations on winnt: ${env.ARCH}







Launch compilations on unix: ${env.ARCH}











------- script for solaris unix

runKDBcc.sh

#! /bin/sh

echo $WORKSPACE

cd $WORKSPACE

------- script for windows

runKDBcc.bat

echo %WORKSPACE%

cd %WORKSPACE%

------- The results on windows with workspace bad name after label.

test:

[echo] Launch compilations on winnt: winnt

[exec]

[exec] The syntax of the command is incorrect.

[exec] C:\slave_hudson\workspace\test_matrix\label\winnt>echo C:\slave_hudson\workspace\test_matrix\label/winnt

[exec] C:\slave_hudson\workspace\test_matrix\label/winnt

[exec]

[exec] C:\slave_hudson\workspace\test_matrix\label\winnt>cd C:\slave_hudson\workspace\test_matrix\label/winnt

[exec]

Raw content of original issue

WORKSPACE environment variable should have a windows format on windows platform.

The synthax is <Hudson_Root>\workspace\<project name>\label/windows if (windows is the node alias)

This is for me a major drawback as workspace env variable is important.


To reproduce:

environment

```
master on unix (solaris)

slave on windows
```

Start with the matrix project configuration and build.xml reproduction, then run runKDBcc.bat on a Windows slave while inspecting how WORKSPACE is assembled for the matrix label. Compare the observed mixed-separator value with the expected Windows path. Done means the reproduction can echo and cd to a valid Windows WORKSPACE path.
