maven项目使用jacoco插件检测代码覆盖率详细配置

使用maven构建项目（java项目或者web项目都可以）

jacoco插件的配置参考官方网址：http://www.eclemma.org/jacoco/trunk/doc/maven.html

（1）配置jacoco的依赖jar包

<dependency><groupId>org.jacoco</groupId><artifactId>jacoco-maven-plugin</artifactId><version>0.7.8</version>
</dependency>

 

（2）配置jacoco的插件，以及相关的goal

 <plugin><groupId>org.jacoco</groupId><artifactId>jacoco-maven-plugin</artifactId><version>0.7.8</version>
　　　　<!--这里的execution ,每一个执行的goal,对应的id必须是唯一的--><executions><execution><id>prepare-agent</id><goals><goal>prepare-agent</goal></goals></execution>
　　　　　　　　<!--这个check:对代码进行检测，控制项目构建成功还是失败--><execution><id>check</id><goals><goal>check</goal></goals></execution>
　　　　　　　　<!--这个report:对代码进行检测，然后生成index.html在 target/site/index.html中可以查看检测的详细结果--><execution><id>report</id><phase>prepare-package</phase><goals><goal>report</goal></goals></execution></executions></plugin>

 

（3）配置代码检查的约束 rules

<!-- Configuration 里面写配置信息 --><configuration><!-- rules里面指定覆盖规则 --><rules><rule implementation="org.jacoco.maven.RuleConfiguration"><element>BUNDLE</element><limits><!-- 指定方法覆盖到80% --><limit implementation="org.jacoco.report.check.Limit"><counter>METHOD</counter><value>COVEREDRATIO</value><minimum>0.80</minimum></limit><!-- 指定指令覆盖到80% --><limit implementation="org.jacoco.report.check.Limit"><counter>INSTRUCTION</counter><value>COVEREDRATIO</value><minimum>0.80</minimum></limit><!-- 指定行覆盖到80% --><limit implementation="org.jacoco.report.check.Limit"><counter>LINE</counter><value>COVEREDRATIO</value><minimum>0.80</minimum></limit><!-- 指定类覆盖到100%，不能遗失任何类 --><limit implementation="org.jacoco.report.check.Limit"><counter>CLASS</counter><value>MISSEDCOUNT</value><maximum>0</maximum></limit></limits></rule></rules>
</configuration>

 

（4）完整的pom.xml的配置如下

pom.xml
