Hi Shane,
Yes, that’s right.

In eclipse, you went to Preferences/Maven/Installations and changed the Maven installation from embedded to your external Maven 2 installation?

Hi Shane,
Thanks for your reply. No, the errors occurred when using Maven 2. I was using Maven 3 to start with, but quickly switched to Maven 2 when I encountered some (different) errors.
Interestingly, it built from the command line, but not within eclipse using the maven plugin.
But after deleting the older of the two references to xercesImpl in the parent pom file (spotted by Justin – many thanks!), all modules now build without whinging.

Andrew, are you using Maven 3? I had some troubles that sound like this until I switched to Maven 2. Maven 3 seems to be stricter on things like this. m2eclipse comes with Maven 3 by default…

Odd… i just looked at the root pom and indeed there are two definitions for xercesImpl in the root pom dependencyManagement section, one for 2.6.2 and one for 2.4.0. Obviously an oversight… the 2.4.2 declaration should be removed. Actually some the other xml dependencies (xmlParserAPIs) does the same. Oh boy and looking at the geotools poms the versions there are even different… xerces 2.7.1.
Looks like some cleanup is in order

Hi All,
I’m currently getting Geoserver set up in Eclipse (as described here) and
have come across the following issue reported by Maven plugin for eclipse:
[ERROR]
‘dependencyManagement.dependencies.dependency.(groupId:artifactId:type:classifier)’
must be unique: xerces:xercesImpl:jar → version 2.4.0 vs 2.6.2 @
org.geoserver:geoserver:2.2-SNAPSHOT, C:\Workspace\geoserver\src\pom.xml
This happens for all modules that use xercesImpl 2.4.0, instead of version
2.6.2 as referenced by Geoserver.
All modules that use xercesImpl 2.4.0… which ones would those be?
Has anyone else found this problem? How important is it for Geoserver to
use version 2.6.2? Any ideas would be much appreciated.
I know that in the past we tried to get jaxb in the GS classpath which
I hear required a different version of xerces, that resulted in GML
encoding/decoding
not working anymore.
So I guess… pretty important? Justin surely knows more about this, hopefully
he’ll chime in
Cheers
Andrea
