1. Right click on the project and select Properties 
2. Expand Resource and click on Resource Filters
3. Click on Add Filter... to create a new filter 
4. On the dialog box that opens
   1. Select the Exclude all and Files radio buttons
   2. Under File and Folder Attributes enter *.class
5. Click OK

To exclude an entire directory hierarchy, e.g. the target directory, select the Files and folders radio button and the All children (recursive) checkbox.

Edit

Exclude the following for a complete cleanup of Open Resource dialog

1. Files *.class
2. Folder bin
3. Folder build
4. Folder target

Without excluding all 4 it does not work.
