Running PMD through: [CLI] Jenkins

@lssilva thanks for your report.

This seems to be a duplicate of #234

A fix for that issue has already been proposed at #235, and will be included in PMD 5.5.4 and 4.4.5.

In the meantime, you can disable parallel execution in Gradle.

Gradle will run in parallel if:

• org.gradle.parallel=true is present in gradle.properties
• --parallel flag is used when executing gradle

You can override both values using --max-workers 1 to force a single worker being used always, but this will also affect test running in parallel.
