cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'context:component-scan'

Question

I'm getting this error in some legacy code base of ours:

GER: org.xml.sax.SAXParseException; lineNumber: 14; columnNumber: 74; cvc-complex-type.2.4.c: Übereinstimmungsplatzhalter ist streng, aber es kann keine Deklaration für Element 'context:component-scan' gefunden werden.

EN (I found this translation online): The matching wildcard is strict, but no declaration can be found for element 'context:component-scan'

Causing XML

Note: I've added a comment for clarity.

What I've tried

When validating the XML using Eclipse's validate mechanisms, validation completes with no errors or warnings.

While researching this error I found this SO-Question, but none of the answers fixed my error: The matching wildcard is strict, but no declaration can be found for element 'context:component-scan

While Googling the error I found lots of copycat resources that clearly scraped one or another SO-question but unfortunately none of those helped me.

Answer 1

The problem was an accidentally updated dependency. Thanks to Marten for pointing me in this direction. A company specific maven goal updated my dependencies without confirmation and jumped a major version while doing so.

When returning those dependencies to their previous versions the error does not occur anymore.
