java - mvn 不生成所有 Artifact

Question

我对 mvn 配置感到疯狂。 mvn clean deploy只生成主 jar 文件。不是javadoc、sources 和sign 等文件。如果我明确调用 mvn clean jar:jar javadoc:jar source:jar gpg:sign deploy - 它生成 javadoc 和源代码等，但主 jar 是空的。

这是怎么回事!! ？

将插件移至 <pluginManagement> 之外部分。此部分用于管理您的插件，或者更确切地说，处理它们的版本。

激活发生在此部分之外:

<build>
  <pluginManagement>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-source-plugin</artifactId>
        <version>2.2.1</version>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-javadoc-plugin</artifactId>
        <version>2.9.1</version>
      </plugin>
    </plugins>
  </pluginManagement>
  <plugins>
      <!-- Activation occurs here. If you have declared the version of the 
           plugin in the section above, then you can omit the version in
           this section.
      -->
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-source-plugin</artifactId>
        <executions>
          <execution>
            <id>attach-sources</id>
            <goals>
              <goal>jar</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-javadoc-plugin</artifactId>
        <executions>
          <execution>
            <id>attach-javadocs</id>
            <goals>
               <goal>jar</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
  </plugins>    
</build>

mvn package现在应该生成您想要的 Artifact ，如果您部署，它们将被自动拾取。
