What did you do?

We are using go in the Apache PLC4X project in the plc4go sub-project.
When running our build in our CI/CD servers, the Windows builds are failing when running the tests with coverage:

[WARNING] ---------Exec.Err--------- [WARNING] github.com/apache/plc4x/plc4go/protocols/cbus/readwrite/model: C:\Users\cdutz\.mvnGoLang\go1.20.5.windows-amd64\pkg\tool\windows_amd64\cover.exe: fork/exec C:\Users\cdutz\.mvnGoLang\go1.20.5.windows-amd64\pkg\tool\windows_amd64\cover.exe: Der Dateiname oder die Erweiterung ist zu lang.

Path length is too long (Got a German Windows)

So even when executing the command:

go test -v -coverprofile=target/coverage.out ./...

I'm getting the same error, so it's not related to the maven plugin, that we are using.
I even tried moving Go to "C:\Go" but this too didn't help.

For now we're just disabling go coverage on all windows machines, but we'd like to enable it again.

What did you expect to see?

I would expect the build to not fail on windows

What did you see instead?
