When using the Node Label Parameter plugin it breaks any build steps that run Windows batch files if you don't fill in a value for the Name field.

To reproduce, create a new free style job and select the "This build is parameterized" option. Select a default slave that is a windows machine. Leave the Name field empty.

Add a build step to run a Windows batch file and fill in a simple command like echo %PATH% or ver. When you run the job the build step will fail with an error message like this:

Build step 'Execute Windows batch command' marked build as failure

This only happens if you leave the Name field empty as I originally did. It also only affects Windows batch files, linux shell command build steps work as expected even with an empty Name field.
