Question

Hi I need to assembly jars from multimodule project in master directory. Let us have a structure like this:

MASTER(pom)
|
+-A3(pom)
| +-A1(jar)
| +-A2(jar)
+-B3(pom)
  +-B1(jar)
  +-B2(jar)

What I want to achieve is to assembly all jar packaged modules in MASTER.

jars/
+- A1.jar
+- A2.jar
+- B1.jar
+- B2.jar

For now I achieved only good resolution on submodules (A3 and B3) by creating pom.xml like:

<modules>
 <module>../A1</module>
 <module>../A2</module>
</modules>
<build>
    <plugins>
        <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
                    <configuration>
                        <descriptors>
                            <descriptor>src/main/assembly/bin.xml</descriptor>
                        </descriptors>
                    </configuration>
        </plugin>
    </plugins>
 </build>

and assembly descriptor:

<moduleSets>
  <moduleSet>
    <includes>
      <include>org.mycompany:A1</include>
      <include>org.mycompany:A2</include>
    </includes>
    <binaries>
      <includeDependencies>false</includeDependencies>
      <outputDirectory>jars/${artifactId}</outputDirectory>
      <unpack>false</unpack>
    </binaries>
  </moduleSet>
</moduleSets>

When I do

mvn clean package assembly:assembly

on submodules (A3 or B3) separately they seem to assembly their own submodules fine.

I don’t know how to specify assembly descriptor in MASTER. The one similar to A3 and B3 descriptor does not deal with it ([ERROR] you must specify at least one file). I tried several additional tags like includeSubModules… still nothing.

Answer 1

Resolution as promised (Master Assembly Descriptor):

<moduleSets>
 <moduleSet>
    <binaries>
        <includeDependencies>false</includeDependencies>
        <outputDirectory>jars/${artifactId}</outputDirectory>
        <unpack>false</unpack>
    </binaries>
 </moduleSet>
</moduleSets>

as you can see – no pointing to specific modules with <include> like in A3 and B3

<includes>
 <include> 
  (...) 
 </include>
</includes>

this is strange indeed. Nevertheless working.
