How to exclude specific folders or files from validation in Eclipse?

Viewed 66485

We have a bunch of malformed XML files used in unit tests to check if our application can handle them.

Eclipse marks this XML files with errors, polluting the "problem view".

Is there a way to exclude a specific folder from Eclipse validators?

In the Validation section of Window > Preferences you can add different rules in settings (...) column, you can add a "Folder or file name rule" in the Exclude Group for XML types.

This is what I do to exclude a folder from validation in a project. For me this works for javascript and other warnings/errors.

  • Right Click Folder
  • Click Resource, ResourceFilters
  • Click "Add"
  • Set the following Exclude All, Files and Folders, All Children, add an asterisk (*) to the File and Folder Attributes input field (highlighted in the image below)

Note: In Eclipse Indigo you have to Right click the folder and select properties and then select resource in the left navigation.

With Eclipse 2018-12 in an Angular-Project, i was able to get rid of validation errors in the folders, npm generates (like node_modules), just by selecting a folder and check the "Derived" check mark under "Resource".

eclipse - ignore validation on folders by check the "Derived" check mark under "Resource"

After a Project -> Clean the Errors are gone.

you may also adjust the output/view side. So go to Show-Menu of Problem-View and filter Display only for selected Items. enter image description here
