I've run into this as well.  If you depend on an artifact that in turn
has system scoped dependencies, the build fails during validation (mvn
-X gives you more info).  Either the intention is to keep system scoped
dependencies defined in the pom of the project you're building (and keep
them out of artifacts intended to be shared as dependencies), or it's a
bug (?).

I got around this by deploying the third party jar into our internal
repository and scoped it as 'provided'.  I created a third party
repository just for this reason.

Subject: Add third parties libraries as dependencies


I'm persuading my Team Leader to use Maven as build tool, but I have to
demonstrate him that with Maven we'll handle our project dependencies
effortless.

I've obtained good results, but I have some problems with some jar
libraries provided, through a quite complex installation process, by a
software.

So I've tried to create an "empty" Maven artifact which has these
libraries as system dependencies (yes, the dependency scope is system).

After I installed the artifact, I inserted it as a compile dependency
for another project called, for example, ABC. But when I try to resolve
projects dependencies I obtain the following message:

    [WARNING] POM for ''<artifact-info>" is invalid. It will be ignored
for artifact resolution.
                       Reason: Failed to validate POM for project
<artifact-info>

And the resolution fails.

Instead if I put these libraries as system dependencies of project ABC,
everything works. I think, because it's not written in Maven
documentation, that system dependencies are not transitive....I'm right
??

But my question is: I can use these external libraries as dependencies
without put them in a local repository ??

Thank you for help,

Claudio Di Vita
