Possibly coincidental but appears to have worked up until Google Cloud CLI update 518.0.0 (2025-04-15)

Hello @howesda any update on this bug ??

I worked round it in the end by changing my build process to build a new image that contained python and then ran the mvn build, but as far as I am aware, the existing problem still exists
