Custom plugin ClassCastException: BasicComponentConfigurator

["Winterflood, Jonathan" <jo...@capgemini.com>]

Hi list,

 

The project I'm working on uses a custom made plugin to download and run
specific versions of artefacts, using their POMs to get their
dependencies.

 

In-house, this works fine, and for our user on the clients machines
(SunOs 5.9, not that it should matter?), also.

However, a different user on a different client's machine (SunOs 5.10,
in theory same mvn and java; also tried a machine with SunOs 5.8) fails
with

java.lang.ClassCastException:

AFAICT, the plugin artefact is the same for both environments. (cmp on
the pom and jar in the local repositories says so)

The effective-poms are the same, to the exception of the build folders,
and the version of the help-plugin used.

 

Googleing only found things relative to ant tasks in the pom, which is
not the case here (slightly compressed):

 

<?xml version="1.0" encoding="UTF-8"?>

<project [...]>

  <modelVersion>4.0.0</modelVersion>

  <groupId>fr.ifremer.sih</groupId>

        <version>1.1</version>

        <configuration />

   </plugin> </plugins> </build>

</project>

 

 

I'm at loss as where to look for this problem, and the exception is
rather unhelpful...

 

Any suggestions welcome

Thanks in advance,
