@DisableCachingByDefault(because="Gradle would require more information to cache this task") public abstract class Exec extends AbstractExecTask<Exec>
Executes a command line process. Example:

     task stopTomcat(type:Exec) {
       workingDir '../tomcat/bin'

       //on windows:
       commandLine 'cmd.exe', '/d', '/c', 'stop.bat'

       //on linux
       commandLine './stop.sh'

       //store the output instead of printing to the console:
       standardOutput = new ByteArrayOutputStream()

       //extension method stopTomcat.output() can be used to obtain the output:
       ext.output = {
         return standardOutput.toString()
       }
     }
