Unable to locate Spring NamespaceHandler for element ... [DEBUG INFO]

[smarek]

Hello,

I've run this morning into issue which is already discussed in this forum.
I haven't found relevant thread to post into, so I'm creating a new one.

I've tried to debug this problem and I found this:

First, I made a Project > Maven > Update Project Confguration

And after this, all NameSpace resolving was OK.

When using Project > Spring Tools > Add Spring Project Nature : DIFF

This is what is added

diff -r first/.project second/.project
32a33,37
> 		<buildCommand>
> 			<name>org.springframework.ide.eclipse.core.springbuilder</name>
> 			<arguments>
> 			</arguments>
> 		</buildCommand>
34a40
> 		<nature>org.springframework.ide.eclipse.core.springnature</nature>

And With these changes the NameSpace resolving breaks.

Then I tried to remove the nature, but until I run again "Update Project Configuration" (Maven), it won't repair
Not even restarting STS works.

This ISSUE can be related to this:
http://jira.codehaus.org/browse/MASSEMBLY-360

But obviously this is related to Spring "Beans Validator" plugin (or whatever it is), as we can get rid of these Validation marks through disabling Spring > Project Validators > Beans Validator > XSD Tool Annotation Rule

So that means, the namespaces are resolved correctly outside of Spring Validator

STS Version: 2.9.1.RELEASE (201203221000)

Hey!

Can you attach a small sample project that illustrates/reproduces the problem you are describing? That would be great and highly appreciated!!!

Cheers,
