PMD is a source code analyzer. It finds common programming flaws such as unused variables, empty catch blocks, and unnecessary object creation. It also includes the Copy/Paste Detector (CPD) that finds duplicated code.
Use the following steps to run PMD on a Maven project:
Open the Maven project for which you want to do a PMD analysis (for instance,
project-with-violations).Run the following command:
mvn pmd:pmd pmd:cpdObserve the output:
[INFO] --- maven-pmd-plugin:3.2:pmd (default-cli) @ project-with-violations --- [WARNING] Unable to locate Source XRef to link to – DISABLED [INFO] --- maven-pmd-plugin:3.2:cpd (default-cli) @ project-with-violations --- [WARNING] Unable to locate Source XRef to link to - DISABLED [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS
