Excluding/Disabling Validation in Eclipse

Tried solution;

1. Right click project
2. Select properties
3. Select validation
4. Check Enable Project specific settings
5. On the XML Validator row, click the ‘…’ button
6. Select Exclude Gruop
7. Click Add rule
8. Select ‘Folder or file name’
9. Click Next
10. Select files or folder which are not validated.
11. Click Finish
12. Click OK
13. Click OK

This solved my problem. Because eclipse validation gives error for generated GWT files.

Best regards.
