Java – How to get rid of Checkstyle message ‘File does not end with a newline.’


I'm working with a Maven (jar) Project in Netbeans (Windows), which creates Checkstyle reports with the Maven Checkstyle plugin.

No matter what I do, I always get the message: File does not end with a newline for Java class files.

What can I do/configure in either Netbeans or Checkstyle to get rid of the message ?

Versions of used software:

  • WinXP SP3
  • Netbeans 6.7 RC1 (happens with 6.5 too)
  • Maven 2.0.9
  • Maven Checkstyle Plugin 2.2
  • Java 1.6 (Update 14)

In my case that was a problem with improper configuration of that checker. By default it uses system default convention of line endings. I was working on windows and the project was using unix-style line endings. I don't think ignoring the warning is the best strategy, so what I've done is:

<module name="Checker">
    <module name="NewlineAtEndOfFile">
        <property name="lineSeparator" value="lf" />
