Description

If includeTests option is enabled but there are not test classes to check then PMD plugin fails with

Failure executing PMD: [ERROR] Incremental analysis can't check auxclasspath contents
java.io.FileNotFoundException: /home/lyor/workspace/C-B4-Server/analytics/c-analytics-engine-dal-api/target/test-classes (No such file or directory)

In previous version this was quietly ignored - I believe same should be here.

plugin configuration - using PMD 6.2.0 module
