Package: checkstyle Version: 5.7-1 With the release of commons-beanutils 1.9.1 (possibly from commons-beanutils 1.9.0 itself), the org.apache.commons.collections package was removed from this source package, since it was already present in the libcommons-collections3-java source package. Because the wrapper script doesn't include the latter package in the list of jars to add to the runtime path, checkstyle crashes with the following stack trace:
Exception in thread "main" java.lang.NoClassDefFoundError:

To fix this, two things need to be done:
1. Edit the wrapper to load the commons-collections3 jar file.
2. Add a dependency on libcommons-collections3-java
In addition, it may be possible to remove the libcommons-beanutils-java
dependency. A basic test seems to show checkstyle working without the jar file
loaded at runtime.
I've attached a patch that does the two things above.
