Question

我有一个具有以下结构的多模块maven项目：

    app (parent)
    -- pom.xml
    -- app-ear
       -- pom.xml
    -- app-ejb
       -- src
       -- pom.xml
    -- app-web
       -- src
       -- pom.xml

应用程序/ pom.xml的

这是我的 app / pom.xml （父项目），我放置了所有应用程序依赖项：

我的问题是 app.ear / app-web.war！META-INF / MANIFEST.MF 和 app.ear / app-ejb.jar！META-INF / MANIFEST .MF 看起来像这样：

    Manifest-Version: 1.0
    Build-Jdk: 1.6.0_24
    Class-Path: lib/javax.faces-2.0.9.jar lib/richfaces-core-api-4.2.0.Fin
     al.jar lib/richfaces-core-impl-4.2.0.Final.jar lib/richfaces-componen
     ts-api-4.2.0.Final.jar lib/richfaces-components-ui-4.2.0.Final.jar li
     b/cssparser-0.9.5.jar lib/sac-1.3.jar lib/guava-10.0.1.jar lib/jsr305
     -1.3.9.jar
    Created-By: Apache Maven
    Archiver-Version: Plexus Archiver

我真的必须从这些MANIFEST中删除Class-Path条目。

为什么呢？因为似乎RichFaces在我的应用程序的类路径中被加载了两次。（一个来自app.ear / lib文件夹，另一个来自app.ear / app-web.war！META-INF / MANIFEST.MF Class-Path条目）。当我尝试在我的Application Server（Oracle Weblogic 10.3.5）中部署app.ear时，我遇到了一些错误：

    INFO: Unsanitized stacktrace from failed start...
    java.lang.IllegalArgumentException: duplicate key: class   javax.faces.validator.RequiredValidator
at com.google.common.base.Preconditions.checkArgument(Preconditions.java:115)
at com.google.common.collect.RegularImmutableMap.<init>(RegularImmutableMap.java:72)
at com.google.common.collect.ImmutableMap$Builder.fromEntryList(ImmutableMap.java:221)

at org.richfaces.application.ValidatorModule.configure(ValidatorModule.java:60)
at org.richfaces.application.ServicesFactoryImpl.init(ServicesFactoryImpl.java:27)

奇怪的是，如果我在 app-web 项目中运行mvn package，则类路径条目不会转到app-web.war / META-INF / MANIFEST.MF 。只有在我的 app 父项目中运行mvn package时才会出现这种情况。

那么，我怎样才能删除webModule和ejbModule MANIFEST文件的Class-path条目？

我在this thread中发现了类似的问题但没有解决方案。

我感谢任何帮助。

谢谢，毛

Answer 1

您需要在配置标记内的 app-ear / pom.xml 中添加以下条目

<archive>
    <manifest>
        <addDefaultImplementationEntries>true</addDefaultImplementationEntries>
    </manifest>
    <manifestEntries>
        <Created-On>${build.timestamp}</Created-On>
        <Ant-Version>${ant.version}</Ant-Version>
        <Java-Version>${ant.java.version}</Java-Version>
    </manifestEntries>
</archive>

通常，设置为false的addDefaultImplementationEntries标记会阻止在清单中写入所有默认条目（例如您想要的条目）。之后，您可以添加任何想要包含的内容。我添加了一些您可以看到的样本。
