Maven版本插件失败：源工件被部署两次

Question

我们在hudson上使用了Maven发布插件，并试图实现发布过程的自动化。发布：准备工作正常。当我们尝试执行release：perform时，它会失败，因为它尝试将源工件两次上载到存储库。

我尝试过的事情

1. 从超级pom中删除确实包含maven源插件的配置文件（不起作用）
2. 在hudson上将发布目标指定为-P！attach-source release：prepare release：perform。我认为这将使源插件无法执行。（不工作）。
3. 尝试将插件阶段指定为超级pom中的某个不存在的阶段（无效）
4. 尝试将插件配置forReleaseProfile指定为false。（猜猜怎么着？没用过）

它仍然会吐出此错误。

对此的任何帮助将不胜感激。

尝试跑步mvn -Prelease-profile help:effective-pom。您会发现您有两个执行部分maven-source- plugin

输出将如下所示：

    <plugin>
      <artifactId>maven-source-plugin</artifactId>
      <version>2.0.4</version>
      <executions>
        <execution>
          <id>attach-sources</id>
          <goals>
            <goal>jar</goal>
          </goals>
        </execution>
        <execution>
          <goals>
            <goal>jar</goal>
          </goals>
        </execution>
      </executions>
    </plugin>

要解决此问题，请找到您使用过的所有地方maven-source-plugin，并确保使用“ id”附加源，使其与发布配置文件相同。然后这些部分将被合并。

最佳实践表明，要获得一致性，您需要在项目的根POM中的build> pluginManagement中而 不是
在子poms中进行配置。在子pom中，您只需在build> plugins中指定要使用maven-source-plugin，但不提供执行。

在房间pom.xml中：

<build>
  <pluginManagement>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-source-plugin</artifactId>
        <executions>
          <execution>
            <!-- This id must match the -Prelease-profile id value or else sources will be "uploaded" twice, which causes Nexus to fail -->
            <id>attach-sources</id>
            <goals>
              <goal>jar</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>    
  </pluginManagement>
</build>

在子pom.xml中：

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-source-plugin</artifactId>
    </plugin>
  </plugins>
</build>
