1.在pom.xml下<build>级下添加内容

  	<plugins>
	  	<plugin>
	  		<groupId>org.apache.maven.plugins</groupId>
	     	<artifactId>maven-surefire-plugin</artifactId>
	     	<configuration>
                <argLine>
                -Xmx1024m -XX:MaxPermSize=256m
                ${argLine}
                </argLine>
	     		<!-- 打包时是否跳过单元测试 -->
	         	<skip>false</skip>
	     	</configuration>
		 </plugin>

                          </goals>

                      <execution>

                          <goals>
                              <goal>report</goal>
                          </goals>
                      </execution>
    			</executions>

	</plugins>
  	<pluginManagement>
  		<plugins>
  			<!--This plugin's configuration is used to store Eclipse m2e settings only. It has no influence on the Maven build itself.-->
  			<plugin>
  				<groupId>org.eclipse.m2e</groupId>

  				<configuration>
  					<lifecycleMappingMetadata>
  						<pluginExecutions>
  							<pluginExecution>
  								<pluginExecutionFilter>
  									<groupId>org.jacoco</groupId>
  									<artifactId>
  										jacoco-maven-plugin
  									</artifactId>
  									<versionRange>
  										[0.6.5.201403032054,)
  									</versionRange>
  									<goals>
  										<goal>prepare-agent</goal>

2.保存后执行 mvn install就好了

总结：其实主要的是执行了 mvn jacoco:prepare-agent ,这个命令用于生成jacoco.exec 。然后执行的是 mvn jacoco:report用于生成报表。
