完整的 pom.xml 文件可以在这里查看。正如主题所说，我不明白一件事：当我运行时mvn package，某些阶段会运行两次，如命令的输出所示：

为什么会这样？我怎样才能避免这种情况？

附带问题：如何防止存储库插件交互？

您应该首先更改 maven-source-plugin 的配置，如下所示：

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-source-plugin</artifactId>
            <version>2.2.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>jar-no-fork</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

其次，您应该注释掉 maven-repository-plugin 的执行，因为插件会分叉生命周期：

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-repository-plugin</artifactId>
            <version>2.3.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>bundle-create</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

更改上述两件事后，您将不会重复执行 default-compile 等。
