Error in Eclipse with ordering of libs

[Ken Krugler]

I just sync'd to trunk, ran mvn eclipse:clean eclipse:eclipse, and  
refreshed my three Tika projects.

tika-app and tika-core were fine, but tika-parsers had 6 errors.  
Mostly things like:

XMLConstants.NULL_NS_URI cannot be resolved

It looks like the geronimo-stax-api_1.0_spec-1.0.jar contains some of  
these classes, and is slightly out of date.

So I had to edit the Eclipse Java Build Path/Order and Export list to  
move the JRE above the geronimo jar.

No idea if this is something that's controllable from Maven.

Hmm, no idea about that either. I'm using the m2ecplise plugin [1] and
I've never seen such issues.

You may want to try upgrading the geronimo-stax_api dependency version
to 1.0.1. though I'm not sure if that helps.

Since it's a library ordering issue, and there's no explicit  
specification for ordering in the pom.xml, I don't think it's an issue  
of the default Maven Eclipse plugin.

Though perhaps m2eclipse always puts the JRE first in the resulting  
list - what's the relative position of the JRE vs. Geronimo in your  
project's properties?

It does - thanks for pointing out the update. Though since it was  
released in 2007-12-23, it makes me wonder what other dependencies are  
way out of date.

I filed https://issues.apache.org/jira/browse/TIKA-299 just to track  
this.
