Preventing checkstyle from running in a specific maven submodule
If you do not want to change your pom.xml you may set the skip to true from command line using the –D option. This was mentioned above as “overridden the skip parameter within an execution”. This is quite similar to -Dmaven.test.skip=true usage. mvn site -Dcheckstyle.skip=true

Empty new line at the end of the Java source files
I think they are trying to ensure every file ends with a trailing newline character. This is different from ending with a blank line, a.k.a. empty newline.
