Bounty: 50

I need to maintain a jenkins groovy script (we are not sure however if it ever worked).The script for a pipeline build has multiple stages (‘revision’ and ‘build’ stages before ‘unit tests’ have succeeded), one of which is the following:

enter image description here

stage('Unit Tests')
        {
            stages
            {
                stage('Tests')
                {
                    parallel
                    {
                        stage('TRKengineTest')
                        {
                            steps 
                            {
                                bat '"C:\Program Files (x86)\NUnit.org\nunit-console\nunit3-console.exe" TRKengine\TRKengine.Test\bin\Release\netcoreapp3.1\TRKengine.Test.dll --result=TRKengine.Test.xml;format=nunit2 --timeout=180000  --workers=1'
                                echo "Something to do?"
                            }
                        }
                        stage('TRKengineGUItest')
                        {
                            steps 
                            {
                                //bat '"C:\Program Files (x86)\NUnit.org\nunit-console\nunit3-console.exe" TRKengine\TRKengineGUI.Test\bin\Release\netcoreapp3.1\TRKengineGUI.Test.dll --result=TRKengineGUI.Test.xml;format=nunit2 --timeout=180000 -v --workers=1'
                                echo "Nothing to do"
                            }
                        }
                    }
                }
                stage('Testresults')
                {
                    steps
                    {
                        nunit testResultsPattern: 'TRKengine.Test.xml, TRKengineGUI.Test.xml'
                    }
                }
            }
        }

The bat command returns a -100 error. More precisely:

Results (nunit2) saved as TRKengine.Test.xml

script returned exit code -100

I have tried a couple of things:

1)First of all, it seems like the path of nunit-console.exe is wrong but as I found out, it can be used in recent releases of nunit.

2)The path of the test.dll is correct, as I manually navigated there and ..netcoreapp3.1TRKengine.Test.dll is indeed there.

3)I have spotted –result=TRKengine.Test.xml;format=nunit2 in other exampels across the internet.

4)I experimented with removing any combinations of the remaining parameters, workers/timeout -v etc, without success.

So the line where the error appears, seems to be correct, and my intuition is that probably the mistake has already happened somewhere else.

I am not sure what "invocation" means. I have also checked How do you run NUnit tests from Jenkins? that seems related and it feels like Winston33 ‘s proposition is exactly like what is happening here.

Something that is a bit worrying is that my machine is 64 bits but the path is ..x86.

I also have access to code and all projects inside the solution build successfully

I am a total beginner in both jenkins and groovy, so if I had not disclosed any necessary information please notify me.

Any help would be greatly appreciated.
