[FR]: Pass --aux-classpath to PMD

### What is the current behavior?

Some lints are not caught correctly because the linter cannot resolve the correct type for all expressions.

### Describe the feature

Pass all the jar dependencies for each source file that is being linted through the --aux-classpath flag provided by PMD.

No file or test is named. Start by locating the PMD invocation and the data available for each linted source file, then trace how its jar dependencies could reach PMD's --aux-classpath option. Done means each source file is linted with its dependencies supplied so PMD can resolve types correctly.
