LinkageError when executing an Ant task that implement BuildListener [message #326781]

Hi,

I have a plugin that contains ANT tasks. One of these task implement
org.apache.tools.ant.BuildListener

All the tasks are working fine except the one implementing BuildListener.
I receive:
BUILD FAILED
Test.xml:18: The following error occurred while executing this line:
java.lang.LinkageError: org/apache/tools/ant/BuildEvent

when launching the target inside eclipse. Some interesting observation:
1- This task works when the target is launched from outside eclipse.
2- Also, it works inside eclipse but when I launch the build in the same
JVM and this is not exactly what I want.

Hope someone can help

thanks

I would take an educated guess that your Ant tasks were compiled against an
incompatible version of BuildEvent.
Are you using the same Ant home entries for all runs?
