Will do. Thanks for the response. Howard

additionalClasspathElements is a list and it does not accept arguments via system properties [1] http://mojo.codehaus.org/exec-maven-plugin/java-mojo.html#additionalClasspathElements There is a feature request to allow list arguments using an external system property string.

Here's the story: We have a project that is basically a platform for executing contributed code. There's more to it of course, but that's the part of it we are having trouble with. Basically, users send our servers messages (RabbitMQ) that include the names of classes to instantiate and methods to execute. The code is in jar files that do live in our maven repository. We have been trying to run our code using mvn exec, for example mvn -X-e exec:java -Dexec.mainClass=org.renci. databridge.engines.relevance.RelevanceEngine -Dexec. additionalClasspathElements="/projects/databridge/howard/ repository/org/renci/databridge/contrib/similarity/ mocksimilarity/1.0-BETA/mocksimilarity-1.0-BETA.jar" -Dexec.classpathScope=runtime but we can't instantiate the class. Here's an example trace: Jan 30, 2015 11:03:44 AM org.renci.databridge.engines.relevance.RelevanceEngineMessageHandler processCreateSimilarityMessage SEVERE: Can't instantiate class org.renci.databridge.contrib. similarity.mocksimilarity.MockSimilarity java.lang.ClassNotFoundException: org.renci.databridge.contrib. similarity.mocksimilarity.MockSimilarity at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at org.renci.databridge.engines.relevance.

RelevanceEngineMessageHandler.handle(RelevanceEngineMessageHandler. java:56) at org.renci.databridge.engines.relevance. RelevanceEngineMessageListener.run(RelevanceEngineMessageListener .java:119) I don't think it's the code, because if I put a dependency in the pom it does work, but we don't want to do that. Maybe it's a bad idea to try to run this through mvn, but it does seem like there should be some way to add jars to the maven runtime class path without adding to the pom. Of course, it's also possible the problem isn't in maven. Any suggestions (other than RTFM!) would be helpful.
