Maven从项目继承依赖关系到另一个项目

Question

Given a Maven project A producing a jar:

<groupId>myprojects</groupId>
<artifactId>A</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
<dependencies>
    <dependency>
        <groupId>some.needed.group</groupId>
        <artifactId>some.needed.artifact1</artifactId>
    </dependency>
    <dependency>
        <groupId>some.needed.group</groupId>
        <artifactId>some.needed.artifact2</artifactId>
    </dependency>
</dependencies>

and a project B depending on A and producing an enterprise archive:

<groupId>myprojects</groupId>
<artifactId>B</artifactId>
<version>1.0</version>
<packaging>ear</packaging>
<dependencies>
    <dependency>
        <artifactId>A</artifactId>
        <version>1.0</version>
    </dependency>
</dependencies>

how can I achieve to have the project B ear artifact to include not only the project B's jar artifact but also its dependent artifacts some.needed.artifact1 and some.needed.artifact2?

I edited and added this because it seems that the behaviour occurs only when running mvn from Bamboo: The strange thing is that it is working when I'm running mvn locally from Eclipse but not when it's being ran by the Bamboo continuous integration server. On a local run I have the application.xml generated correctly with references to all the transitive dependencies the corresponding jar files copied to the lib folder. On Bamboo plan the generated application.xml does not include the references and the jar files are not in the lib folder.

Answer 1

First as a correction I think dependency should be on A, not on B , like this :

   <dependencies>
    <dependency>
        <artifactId>A</artifactId>
        <version>1.0</version>
    </dependency>
 </dependencies>

And about the original question of having the dependent jars , i think they should be available in your EAR file , as you have dependency on A project and which in turn depends on some.needed.artifact1 and some.needed.artifact2 (transitive dependencies) as the scope you provided is default so maven will take it as compile and all the jars will be bundled in your ear file.

Thanks

In project B which produces the ear, you can include a dependency to A like this

<modules>
  <module>project A</module>
</modules>
<dependencies>
  <dependency>
    <groupId>some.needed.group</groupId>
    <artifactId>A</artifactId>
    <version>1.0</version>
  </dependency>
</dependencies>

In project A, define the parent project to be project B like the following

<parent>
        <groupId>myprojects</groupId>
        <artifactId>B</artifactId>
        <version>1.0</version>
        <name>project B</name>
</parent>
<name>project A</name>
