Maven 多模块 EAR - 不添加子模块

Question

I have a Maven multi-module project (Jakarta EE 8) based on the wildfly-jakartaee8-with-tools archetype being deployed on Wildly 26 and using the maven-ear-plugin (3.2.0)

This is the project structure

-WebApp.ear
    -Web-entities.jar
    -Web-ejb.jar
    -Web-web.war
    -Web-mobile.war
    -Web-api.war

Here is the Web-ear pom.xml

            Due to Maven's lack of intelligence with EARs we need to configure
            the WildFly Maven plug-in to skip deployment for all modules. We then enable
            it specifically in the ear module. -->

            </configuration>
        </plugin>
    </plugins>
</build>

But when I build the generated application.xml does not include any of the child modules.

If I set generateApplicationXml to false, then manually create the application.xml with the modules specified it still does not add the child modules in the output EAR. but if I set <scope>compile</scope> on the module dependancies in the ear pom it does include them - but this seems wrong to me as all the examples I see uses <scope>provided</scope> ?

I can see that Maven is building each child module correctly and they are present in the /target output folder of the sub-module but its just not adding them to the EAR output, I just get an empty EAR with meta-info

Answer 1

I found that the cause of this was in the project parent pom.xml the child dependancies were labeled with <scope>provided</scope> thus preventing the child modules from being packaged, removing this fixed the issue
