I am trying to debug a Java / Maven project with a lot of depencies on various libraries. When I run it on a Linux server the program starts up fine, but when I try to run it in Eclipse it throws the following exception:
Exception in thread "main" java.lang.NoSuchMethodError: org.apache.camel.model.RouteDefinition.getErrorHandlerBuilder()Lorg/apache/camel/ErrorHandlerFactory;

Now, I can see that the RouteDefinition class is in the camel-core-2.9.3,jar and I can see that this library is imported. So how come it doesn't see that method?
How do I go about debugging this?
Could I get info from the process running on the Linux server? For example can I get the list of Jars that are imported and the order in which they are imported?
Many thanks!
The error that you're getting is caused by Maven pulling in the wrong version. Try deleting all versions out of your local repo, add it explicitly to your pom, clean out all of your builds, pray to the eclipse gods, etc. If it still gives you the error, check your local repo to see which wrong versions it pulled in, figure out what depends on them, and add explicit ignores for them while keeping the explicit include.
