----------------------------------
Summary: NoClassDefFoundError when using executions in maven
Key: MNG-5543
URL: https://jira.codehaus.org/browse/MNG-5543
Project: Maven 2 & 3
Issue Type: Bug
Components: Integration Tests
Affects Versions: 3.1.1

Reporter: John Farrelly
*I've created the smallest maven POM file I can to highlight the problem (see
below)*.
I'm using an email server plugin (for integration testing). I can launch the
plugin no problem:
mvn emailserver:run
[INFO] --- emailserver-maven-plugin:1.1.1:run (default-cli) @ project ---
[INFO] Starting Greenmail mail server...
[INFO] Started Greenmail mail server
[INFO] Waiting for command from client
However, I have configured the plugin to run before the `integration-test`
lifecycle. When run this way, I get a `NoClassDefFoundError`:
mvn integration-test
Exception in thread "Thread-1" java.lang.NoClassDefFoundError:
com/icegreen/greenmail/util/ServerSetup
When I execute maven with `-X` to see what's happening, in both cases it shows
the same dependency tree as far as I can see, so I'm at a bit of a loss as to
why I'm getting an exception which it's launched through lifecycle phases.
Hopefully someone can help!

*NOTE*
This appears to be a problem on 3.1.1 only. I downloaded 3.0.5 and it worked
as expected.
