Issues building a spring boot application from within a Dockerfile on Linux

Question

I'm having difficulty building a spring boot application from within a Dockerfile on Linux.

It works just fine on Windows.

I've seen other posts where folks say I should specify or remove the relativePath in the pom.xml file, but I don't think that's the issue nor did it work.

Here's my error, followed by my code:
