Quickstart

After you have installed the Checkclipse plug-in by unzipping it to the plugins directory, start your Eclipse workbench. Open the properties page of any Java project in the Package Explorer and choose the entry "Checkclipse". On this page just check the checkbox "Enable Checkstyle" and press OK.

Now the Java project is rebuilt and additional warning markers will appear in the Problems View if some code is violating the default Checkstyle configuration delivered with this plugin.

Please note, that the default Checkstyle configuration delivered with the Checkclipse plug-in is rather lax. You should create yourself a more strict configuration.

Pitfalls

If no style violations turn up, don't be optimistic that you already are perfectly stylish. There might be some points in the configuration preventing markers to show up.

The following is a list of possible sources of missing problems:

• The "Build Automatically" Check Box of Eclipse under Window->Preferences->General->Workspace is turned off. This prevents even the Java Compiler to automatically build your changed files.
• The Navigator is open instead of Package Explorer. Problem markers are usually not shown there.
• The Problems View is not open.
• There is a filter installed on the Problems view which suppresses the warnings. Check the filter settings in the drop-down menu on the upper right corner of the Problems View.
