Java – Multi Module Maven2 Project with WTP

eclipseeclipse-wtpjavamaven-2

I'm having a hard time to make my Maven2 multi module project, with a deep project structure, appear as a single ear (with its dependencies – which includes 1 war, 2 ejbs and 1 jar) to be deployed in my JBOSS 5 server inside my Eclipse Ganymede (tab Servers).

I've been trying to use Maven Eclipse Plugin to turn my projects into a WTP project without success. Therefore they appear to be deployed in the server they appear as separated projets.

My project has 1 war, 2 ejbs and 1 jar that must be packaged inside an ear, each of the "subprojects" is a separate module.

Project's pom.xml (type pom):

…

<modules>
   <module>ejb1</module>
   <module>ejb2</module>
   <module>war</module>
   <module>jar</module>
   <module>ear</module>
</modules>

…

The ear module is only responsable to pack the other modules together.

Is there a way to tell eclipse (ganymede) that all those projects (ejbs, war and jar) are inside the ear module so I can deploy the ear in the server?

What you want to do is have maven create the eclipse projects via mvn eclipse:eclipse This might be helpful.

I was able to get my maven build working correctly by adding the following plugin to the ws-war pom file:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
                <execution>
                    <phase>process-classes</phase>
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>
                            ${project.build.directory}/${project.build.finalName}/WEB-INF/services

                    </configuration>
                </execution>
            </executions>

Java – How to create an executable JAR with dependencies using Maven

<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>fully.qualified.MainClass</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

and you run it with

mvn clean compile assembly:single

Compile goal should be added before assembly:single or otherwise the code on your own project is not included.

See more details in comments.

Commonly this goal is tied to a build phase to execute automatically. This ensures the JAR is built when executing mvn install or performing a deployment/release.

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <configuration>
    <archive>
      <manifest>
        <mainClass>fully.qualified.MainClass</mainClass>
      </manifest>
    </archive>
    <descriptorRefs>
      <descriptorRef>jar-with-dependencies</descriptorRef>
    </descriptorRefs>
  </configuration>
  <executions>
    <execution>
      <id>make-assembly</id> <!-- this is used for inheritance merges -->
      <phase>package</phase> <!-- bind to the packaging phase -->
      <goals>
        <goal>single</goal>
      </goals>
    </execution>
  </executions>
</plugin>
