I have a file in my workspace that was generated by a Maven plugin. When I try to read it with

new File(filename).text

a FileNotFoundException was thrown although the file exists. The pipeline doesn't run in a sandbox and there's no method to approve at the In-process Script Approval view.

But I'm able to read that file using the pipeline's readFile method.

I tried both a relative as well as an absolute path to the file.

Is there anything I'm missing or is this a bug?
