How to keep Maven profiles which are activeByDefault active even if another profile gets activated?

Profiles are a good way to bring some order into POM. Especially if you use multiple executions of the same plugin for different purposes.

Using files:

    alwaysActive
    
         .
    
    ...

This will always be true (unless someone deletes the directory during Maven boot :). Tested with Maven 3.6.0.

It might also be a good way to differentiate between types of projects. For instance, my project has always module.json present.

Using a profile activating extension

There are a few Maven extensions for profile activation. One of them in a fork here:
