I know nothing about Jenkins  but it looks like you are trying to access environment variables using some form of unix syntax - that won t work   If the name of the variable is WORKSPACE  then the value is expanded in Windows batch using  WORKSPACE   That form of expansion is performed at parse time  For example  this will print to screen the value of WORKSPACE  echo  WORKSPACE    If you need the value at execution time  then you need to use delayed expansion  WORKSPACE   Delayed expansion is not normally enabled by default  Use SETLOCAL EnableDelayedExpansion to enable it  Delayed expansion is often needed because blocks of code within parentheses and or multiple commands concatenated by  amp    amp  amp   or    are parsed all at once  so a value assigned within the block cannot be read later within the same block unless you use delayed expansion   setlocal enableDelayedExpansion set WORKSPACE BEFORE     set WORKSPACE AFTER   echo Normal Expansion    WORKSPACE    echo Delayed Expansion    WORKSPACE      The output of the above is  Normal Expansion   BEFORE Delayed Expansion   AFTER   Use HELP SET or SET    from the command line to get more information about Windows environment variables and the various expansion options  For example  it explains how to do search replace and substring operations
