What I tried

https://stackoverflow.com/a/2033299/1839360 Added a dependency for pmd-java - it did not work. I tried both versions https://mvnrepository.com/artifact/net.sourceforge.pmd/pmd-java/6.21.0 https://mvnrepository.com/artifact/net.sourceforge.pmd/pmd-java/6.23.0

With the latest version, there is an error

I had to add these dependencies

<dependencies>
    <dependency>
        <groupId>net.sourceforge.pmd</groupId>
        <artifactId>pmd-java</artifactId>
        <version>6.23.0</version>
    </dependency>

    <dependency>
        <groupId>net.sourceforge.pmd</groupId>
        <artifactId>pmd-core</artifactId>
