maven与jacoco插件配置单元测试覆盖率

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>

<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.6.5.201403032054</version>
<executions>
<execution>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>report</id>
<phase>prepare-package</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
</executions>
</plugin>
</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>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<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>
</goals>
</pluginExecutionFilter>
<action>
<ignore></ignore>
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins>
</pluginManagement>

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。
