Difference in timeout handling within a script or a step

[christop...@googlemail.com]

Hello,

I am experiencing a strange difference with catching a timeout within a script in a step or a script called from a step.

The problem I want to work around: in some situations my unit-test exe (GoogleTest) is blocked with a popup from inside the C-runtime. To make the build complete in this szenario I inserted a timeout and want to catch it.

This is working as expected in a szenario like this:

def testModule() {

       try{                                        
           timeout(time: 30, unit: 'MINUTES') {                
               bat "dmake run-test"
            }
        } catch (err) {
            echo "Caught: ${err}"
            unstable( message: "Test timeout in stage ${STAGE_NAME}" )
        }

}

pipeline {

   ...

   stages {

   ...

stage( 'test' ) {
            steps {
                script{
                    testModule( )
                }
            }

        }    

}

}

When I try this instead:

stage('Test'){
      steps {
         script{
            try{                                        
               timeout(time: 30, unit: 'MINUTES') {                
                            bat "dmake runtest"
                        }
                      } catch (err) {
                        echo "Caught: ${err}"
                        unstable( message: "Test timeout in stage ${STAGE_NAME}" )
                      }
                   }

}}

I get  number of exceptions from execution like this:

" Cancelling nested steps due to timeout

11:45:17 After 20s process did not stop

11:45:18 Also: Also: java.nio.file.FileSystemException: D:\workdir\workspace\

and also at the very end:

Does anyone have an explenation for thet difference and can give me a workaround?

TIA,
