使用maven構建項目(java項目或者web項目都可以)
jacoco插件的配置參考官方網址:http://www.eclemma.org/jacoco/trunk/doc/maven.html
(1)配置jacoco的依賴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,以及相關的goal
<plugin> <groupId>org.jacoco</groupId> <artifactId>jacoco-maven-plugin</artifactId> <version>0.7.8</version>
<!--這里的execution ,每一個執行的goal,對應的id必須是唯一的--> <executions> <execution> <id>prepare-agent</id> <goals> <goal>prepare-agent</goal> </goals> </execution>
<!--這個check:對代碼進行檢測,控制項目構建成功還是失敗--> <execution> <id>check</id> <goals> <goal>check</goal> </goals> </execution>
<!--這個report:對代碼進行檢測,然后生成index.html在 target/site/index.html中可以查看檢測的詳細結果--> <execution> <id>report</id> <phase>prepare-package</phase> <goals> <goal>report</goal> </goals> </execution> </executions> </plugin>
(3)配置代碼檢查的約束 rules
<!-- Configuration 里面寫配置信息 --> <configuration> <!-- rules里面指定覆蓋規則 --> <rules> <rule implementation="org.jacoco.maven.RuleConfiguration"> <element>BUNDLE</element> <limits> <!-- 指定方法覆蓋到80% --> <limit implementation="org.jacoco.report.check.Limit"> <counter>METHOD</counter> <value>COVEREDRATIO</value> <minimum>0.80</minimum> </limit> <!-- 指定指令覆蓋到80% --> <limit implementation="org.jacoco.report.check.Limit"> <counter>INSTRUCTION</counter> <value>COVEREDRATIO</value> <minimum>0.80</minimum> </limit> <!-- 指定行覆蓋到80% --> <limit implementation="org.jacoco.report.check.Limit"> <counter>LINE</counter> <value>COVEREDRATIO</value> <minimum>0.80</minimum> </limit> <!-- 指定類覆蓋到100%,不能遺失任何類 --> <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
