Below I said the Run command, F5, would not work, but rather to use the
Prompt command, Alt+F5. The %SourceRootLong% token substitutes the root
name of the file in the current editing window (such tokens are explained
in the documentation). For example, if your file name is C:\temp\long
name.java then the short root name would probably be
LONGNA~1
and the long root name would be
long name
If the root names of your files are 8 characters or less and have no
embedded spaces, then the short and long root names would be the same.
Although most programs accept a short file name on the command line,
java.exe seems not to do so. It automatically adds the .class
extension, which is why you do not include it.
