Seems the following call is missing a nullcheck: https://github.com/apache/maven-clean-plugin/blob/maven-clean-plugin-3.2.0/src/main/java/org/apache/maven/plugins/clean/Cleaner.java#L541
Compare with: https://github.com/apache/maven-clean-plugin/blob/maven-clean-plugin-3.2.0/src/main/java/org/apache/maven/plugins/clean/Cleaner.java#L121
