Classpath Dependency Validator for user libraries [message #1122415]

Hi all!

I'm using two user libraries in one of my projects:
* One for Hibernate framework (including dependencies).
* One for JasperReports libraries and dependencies.

Both include "commons-collection" as a dependency (in fact, both reference the very same JAR file) and both libraries are marked to be deployed in the "deployment assembly" section, resulting in Eclipse's Classpath Dependency Validator giving the following error:
"The project contains another dependency with the same archive name"

I don't understand why this is considered an error or how to solve it a way other than disabling the "Classpath Dependency Validator" itself.

If I create a project using one (but only one) of those libraries, everything works fine. The error (obviously) only occurs when using BOTH libraries under the same project.

My point is, I don't think I shouldn't care whether I use both libraries or not. Yes, both use the same JAR file... I don't think it's a big deal actually... is it? I mean, both libraries are deployed and one file will get overwritten by itself...

Is there a reason for this to be considered an error?

Is there any workaround other than disabling the validator (or just ignoring the error)?

Thanks so much in advance. Kind regards,
Miguel Angel

how do you specify your dependencies? Is that maven ( and m2e ) behind the curtain, or do you manually specify dependencies in the project's Build Path?

I don't use Maven or any other project/dependency manager other than Eclipse's native ones (Java Build Path & Deployment Assembly)

I can simply ignore the error and go on (that's what I'm doing)... but I'd like to workaround it, if possible, and understand why Eclipse considers it an "error".

Thanks for your response! Smile

Sorry for being dense: what is "Deployment Assembly"?
It doesn't seem to be provided by JDT.
Sounds like s.t. J2EE/WebTools?
In that case the WebTools forum might be a better place to ask.
They would probably also know about the "Classpath Dependency Validator",
which is not a JDT feature, either.
