Java 13 Support

This release of PMD brings support for Java 13. PMD can parse Switch Expressions
with the new yield statement and resolve the type of such an expression.

PMD also parses Text Blocks as String literals.

Note: The Switch Expressions and Text Blocks are a preview language feature of OpenJDK 13
and are not enabled by default. In order to
analyze a project with PMD that uses these language features, you'll need to enable it via the environment
variable PMD_JAVA_OPTS and select the new language version 13-preview:

export PMD_JAVA_OPTS=--enable-preview
./run.sh pmd -language java -version 13-preview ...

Note: Support for the extended break statement introduced in Java 12 as a preview language feature
will be removed with the next PMD version 6.19.0.

Full support for Scala

Thanks to Chris Smith PMD now fully supports Scala. Now rules for analyzing Scala
code can be developed in addition to the Copy-Paste-Detection (CPD) functionality. There are no rules yet, so
contributions are welcome.
