多模块maven项目：使用着色工件生成EAR

Question

我有一个多模块项目，其中一个模块应该从其他模块工件中创建一个EAR。为了使事情变得更有趣，这些其他4个工件必须被阴影分为2个工件：

super-pom
|-- ear module
|-- ejb1
|-- ejb2
|-- web1
|-- web2

它创建的是包含ejb2阴影，web2阴影和ej1，web1的EAR（包含在阴影版本中！）。 奇怪的是，如果我在每个模块中手动运行maven，最后在耳模块中运行maven，我得到了我想要的东西。

我能弄清楚的是，超级巨蛋如何将这些文物偷偷带入EAR。事件maven package -X仅在清除步骤中列出正确的工件：

[DEBUG] Resolving artifact type mappings ...
[DEBUG] Initializing JBoss configuration if necessary ...
[DEBUG] Initializing ear execution context
[DEBUG] Resolving ear modules ...
[DEBUG] Resolving ear module[ejb:com.mycomp:ejb2]
[DEBUG] Resolving ear module[war:com.mycomp:web2]
[DEBUG] Resolving ear module[jar:org.jboss.seam:jboss-seam]
[INFO] Generating application.xml

一些简化的poms，从超级pom开始：

<artifactId>super-pom</artifactId>
<packaging>pom</packaging>
<modules>
    <module>ejb1</module>
    <module>web1</module>
    <module>ejb2</module>
    <module>web2</module>
    <module>ear</module>
</modules>
