Maven - 使用所有依赖的 jar 构建 .ear 文件

Question

我正在使用 Maven 构建一个 java ear 文件。当我们将ear部署到Weblogic时，出现如下异常，这让我觉得需要将依赖添加到ear文件中（maven打包到ear中）：

<Feb 2, 2015 3:20:30 PM EST> <Error> <HTTP> <BEA-101371> <There was a failure when processing annotations for application /6v09bd/Develapp-0.1.war. Please make sure that the annotations are valid. The error is javax.faces.webapp.FacesServlet>

根据this SO solution，我尝试添加 maven 插件“jar-with-dependencies”。但是我收到插件的下载错误，maven 不会编译 pom.xml。而且我不确定这个插件是否真的适用于耳朵文件。

基本上，我需要知道如何将战争的所有依赖项纳入其中，以便 Weblogic 对耳朵感到满意，如果这有意义的话。

Answer 1

我猜你没有使用 maven-war-plugin 来构建你的战争。因为这个插件可以满足你的要求。它会将你的战争依赖项复制到 lib 文件夹中。

请记住，提供的范围依赖项不会被复制。

插件文档：http://maven.apache.org/plugins/maven-war-plugin/

你需要在你的 war/pom.xml 中有这样的东西

<build>
  <finalName>${project.artifactId}</finalName>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <configuration>
        <source>1.7</source>
        <target>1.7</target>
      </configuration>
    </plugin>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-war-plugin</artifactId>
      <configuration>
        <filteringDeploymentDescriptors>true</filteringDeploymentDescriptors>
      </configuration>
    </plugin>
  </plugins>
</build>

别忘了 ear/pom.xml

 <build>
   <plugins>
      <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-ear-plugin</artifactId>
         <configuration>
            <modules>
               <webModule>
                  <moduleId>YOURService</moduleId>
                  <groupId>YOURGroupId</groupId>
                  <artifactId>YOURArtifactId</artifactId>
                  <contextRoot>/DevelApp</contextRoot>
               </webModule>
            </modules>
            <defaultLibBundleDir>APP-INF/lib</defaultLibBundleDir>
            <skinnyWars>true</skinnyWars>
         </configuration>
      </plugin>            
   </plugins>
</build>

如果你有一些特殊的类，想要强制到网络应用程序中，你总是可以使用这个插件：

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-dependency-plugin</artifactId>
   <executions>
      <execution>
         <id>unpack-my-dependencies</id>
         <phase>process-resources</phase>
         <goals>
            <goal>unpack</goal>
         </goals>
         <configuration>
            <artifactItems>
               <artifactItem>
                  <groupId>another.groupId</groupId>
                  <artifactId>another.artifactId</artifactId>
                  <version>another.version</version>
                  <type>jar</type>
                  <overWrite>true</overWrite>
               </artifactItem>
            </artifactItems>
            <outputDirectory>${project.build.directory}/${project.artifactId}-${project.version}/APP-INF/classes
            </outputDirectory>
            <overWriteReleases>true</overWriteReleases>
            <includes>**/*.class</includes>
         </configuration>
      </execution>
   </executions>
</plugin>

您总是可以将依赖项传递给您的战争，只需用<scope>runtime</scope> 标记它（请参阅：maven dependency scope）
