How to ignore XML warnings from a specific folder

问题:

I'm building a java project with Eclipse and the plugin m2e (it adds Maven support in Eclipse).

There some XML Surefire reports ine the target directory. They generate annoying warnings because they have neither a DTD nor an XML Schema.

How can you tell Eclipse to ignore **/target folders ?

回答1:

See the following image:
Open the preferences Window > Preferences

回答2:

1. open the Preferences (Windoww > Preferences)
2. go to xml validation XML > XML Files > Validation
3. set "No grammar specified" to Ignore

Edit: I see you want it for a specific folder... but I'm afraid this only works on workspace or at least project level

回答3:

The whole target/ folder can be excluded from Eclipse's "management" by marking it as derived. Right-click on the target/ folder and go to properties:

This disables validation, excludes this directory from search, "Open Resource" lookup, etc. Unfortunately, you'll have to remember to toggle it after every project Build since it switches back to "off" by default.
