如果jboss版本是4.2，而不是5，那么maven-ear-plugin就可以工作了。为什么？

Question

我正在使用maven来配置maven-ear-plugin。当我说jboss版本是5时，我得到了以下异常(参见下面标签下的代码)。如果我将版本替换为4.2，它就可以工作

<build>
    <finalName>tactical</finalName>
    <plugins>
        <plugin>
            <artifactId>maven-ear-plugin</artifactId>
            <configuration>
                <version>5</version>
                <defaultJavaBundleDir>lib</defaultJavaBundleDir>
                <jboss>
                    <version>5</version>
                    <loader-repository>seam.jboss.org:loader=tactical</loader-repository>
                </jboss>
 <modules>
                    <ejbModule>
                        <groupId>${project.groupId}</groupId>
                        <artifactId>tactical-jar</artifactId>
                    </ejbModule>
                </modules>
            </configuration>
        </plugin>
    </plugins>
</build>

为什么它适用于jboss 4.2而不适用于5。什么?？

我得到了以下异常：

    [INFO] Failed to initialize JBoss configuration

任何想法。谢谢

您使用的是哪个版本的插件？最新的source code表明这应该是可行的。

120             else if ( version.equals( JbossConfiguration.VERSION_5 ) )
121             {
122                 this.jbossFive = true;
123             }
124             else
125             {
126                 throw new EarPluginException(
127                     "Invalid JBoss configuration, version[" + version + "] is not supported." );
128             }

maven ear插件的2.3.2版和更高版本中提供了对JBoss 5的支持(请参阅MEAR-102)。使用您当前的配置(没有指定插件的版本，出于构建重现性的考虑，不建议这样做)，您将获得2.3.1版的插件。您可以通过运行以下命令来打印“有效pom”以进行检查：

mvn help:effective-pom

对于您的情况，我建议使用最新版本：

<build>
  <finalName>tactical</finalName>
  <plugins>
    <plugin>
      <artifactId>maven-ear-plugin</artifactId>
      <!-- Lock down plugin version for build reproducibility -->
      <version>2.4.1</version>
      <configuration>
        <version>5</version>
        <defaultJavaBundleDir>lib</defaultJavaBundleDir>
        <jboss>
          <version>5</version>
          <loader-repository>seam.jboss.org:loader=tactical</loader-repository>
        </jboss>
        <modules>
          <ejbModule>
            <groupId>${project.groupId}</groupId>
            <artifactId>tactical-jar</artifactId>
          </ejbModule>
        </modules>
      </configuration>
    </plugin>
  </plugins>
</build>
