I cannot use my new plugin because I get java.lang.NoClassDefFoundError on something from a 3rd party jar. I have code to import stuff from this jar.Could someone provide some examples on how to get around this problem in pom.xml? Also, does this have to be somewhere defined in the pom.xml for the maven plugin for managing taverna plugins?
The main Maven way to deal with these things is to use the assembly plugin with its built-in jar-with-dependencies descriptor. That makes a JAR that includes all the dependencies within it, plus the metadata magic to make Java know how to use it. http://maven.apache.org/plugins/maven-assembly-plugin/descriptor-refs.html Thus, in my code I have this: <plugin> <artifactId>maven-assembly-plugin</artifactId> <version>2.2</version> <configuration> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> <!-- This next section because I happen to be building an executable JAR; you probably don't need it... --> <archive> <manifest> <mainClass>${workerMainClass}</mainClass> </manifest> </archive> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin> Note that the assembly plugin is *very* complex, but the case you're doing is (probably) one where you don't need to know about all the horrible gory details.
