The columns that are reported by CPD were inconsistent across languages
before. A language like Java (using a JavaCC-based tokenizer) would use
a width of 8 for tabs, whereas a language like C# (using an Antlr-based
tokenizer) would use 1 instead.
This includes unit tests for most languages to ensure a tab character is
counted as 1. The configuration for JavaCC has been adjusted to respect
this as well.
This removes junit-vintage-engine as a test dependency
as well as kotlintest-runner-junit5.
The engines are only needed during test execution, but should
not be available for test compilation.
For this to work, the latest surefire plugin is required.
* Avoid using symlinks, this is very difficult to get working
under Windows
* Provide names for the different scala modules
* Rename pmd-scala to pmd-scala-common
* Restore main module pmd-scala for backwards compatibility
