Question

Eclipse版本： Indigo

目标应用程序服务器： Weblogic 10.3.5（11gR1）

我无法在Eclipse中构建和部署多模块POM项目（打包为EAR）到我的WebLogic服务器。

尽管父POM在IDE之外成功构建了EAR文件，但在尝试将UI WAR部署到Application Server时，我收到以下错误：

尽管在Maven POM中有jsf-api依赖关系并且在UI WAR项目的.classpath文件中引用了它：

用于UI WAR项目的POM片段：

            <artifactId>jsf-api</artifactId>

用于UI WAR项目的

很明显，这是一个类路径问题，但我已经在两天的时间里盯着它看了卷轴，并且已经决定现在是浪费白旗并呼吁求助的时候了！

最终目标是采用我的EAR项目（目前因为每次稍微更改而在命令行上取消部署/重新部署的烦人需求而受阻）并获取它以便我可以在运行的部署中执行热修复在IDE内部。

由于

更新

通过将违规依赖项添加到应用程序服务器的domains\<domain>\lib文件夹，并重新启动应用程序服务器，我现在开始获取ClassNotFoundExceptions其他WAR依赖项。现在很清楚，Eclipse不尊重WAR项目的classpath - 我仍然不明白为什么或如何： - （

Answer 1

要将依赖关系打包到lib目录中，请将其添加到EAR打包pom：

<build>
   <plugins>
      <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-ear-plugin</artifactId>
         <version>2.5</version>
         <configuration>
            <version>6</version>
            <defaultLibBundleDir>lib</defaultLibBundleDir>
            <modules>
               [Your EJB and Web modules here]
            </modules>
          </configuration>
       </plugin>
   </plugins>
</build>

请注意defaultLibBundleDir标记。

Answer 2

在Eclipse中使用File > Export构建EAR后，我能够将EAR与我的Maven POM生成的EAR进行比较。

我发现Eclipse没有在部署程序集中包含对Maven Dependencies构建路径项的引用（我发现仅仅将Projects作为依赖项添加是不够的。）

阅读主题，我发现有必要将子WAR和JAR的Maven依赖项添加到各自的WAR和JAR项目中，但目的地为

../ LIB

在每个WAR上声明，JAR 指的是父EAR的lib文件夹。

使用此菜单的组合（或者通过依次编辑每个受影响的WAR和JAR的每个相应的.settings / org.eclipse.wst.common.component文件）我能够构建一个版本的EAR与通过我的Maven脚本生成的EAR相匹配。

我希望这有助于某人。
