Checkstyle Eclipse plugin doesn't work

Question

I'm using eclipse checkstyle plugin with Juno Eclipse distribution. Anytime the code is checked for checkstyle error I get the following error:

cannot initialize module TreeWalker - Unable to instantiate DoubleCheckedLocking

Does anybody know how to fix this problem? Is it a plugin compatibility issue or something else?

Answer 1

Open the Checkstyle preferences, create your own Check Configuration, go into your own check configuration, find the TreeWalker module, click it and then un-check the DoubleCheckedLocking. As simple as that.

Answer 2

just comment or remove "DoubleCheckedLocking" from the checkstyle file and it will work

Answer 3

• Under your Eclipse Workspace Search for file internal_config__*.xml

• Remove the following line from the file

  <module name="DoubleCheckedLocking"/>

• Reload Workspace.

This will work for any discontinued module which produces the error message "Unable to instantiate"

Answer 4

The DoubleCheckedLocking check has been removed in Checkstyle 5.6 and must be manually removed from your Checkstyle configuration.
