mvn 打包报错 Unable to execute gpg command

 报错详细内容：

Failed to execute goal org.apache.maven.plugins:maven-gpg-plugin:1.6:sign (sign-artifacts) on project jim: Unable to execute gpg command: Error while executing process. Cannot run program "gpg": error=2, No such file or directory -> [Help 1]

原因： 使用的版本是maven3,执行maven-ant-plugin和maven2有一定的不同，需要引入pluginManagement

解决办法：在pom.xml中引入<pluginManagement >：

   <build>
          <pluginManagement>
                <plugins>
                    <!-- GPG -->
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-gpg-plugin</artifactId>
                        <version>1.6</version>
                        <executions>
                            <execution>
                                <id>sign-artifacts</id>
                                <phase>verify</phase>
                                <goals>
                                    <goal>sign</goal>
                                </goals>
                            </execution>
                        </executions>
                    </plugin>
                </plugins>
             </pluginManagement>
