Improve error handlding and message
-----------------------------------
Key: MNG-1351
URL: http://jira.codehaus.org/browse/MNG-1351
Project: Maven 2
Type: Improvement
Components: maven-core
Versions: 2.0
Reporter: Vincent Massol
I don't know yet what the problem is but the stack trace doesn't help me in
solving it. It would be nice to display a more indicative error message:
C:\dev\cargo\trunk\samples\extensions\maven2>mvn
org.codehaus.cargo.maven2:cargo-maven2-plugin:start -X
+ Error stacktraces are turned on.
