如何使用jacoco在多maven模块上实现单元测试覆盖

我有下面的multi-maven模块应用程序，并按照下面的步骤在tests模块中生成一个整合的jacoco单元测试覆盖率报告。然而，我们有一个政策来强制执行80%的最低总覆盖率，否则构建失败。这在单模块应用中非常有效。但是，我无法在多模块应用程序的总体覆盖范围内强制执行此操作。如有任何建议，将不胜感激

-Module1
-Module2
-test

我试图在测试模块的pom文件中设置jacoco check的执行目标，但clean安装成功，没有任何覆盖错误

如果聚合覆盖率不是80%，我预计mvn clean install会抛出错误。

您只是在测试模块上强制覆盖

您应该移动此配置：

  <execution>
    <id>jacoco-check</id>
    <goals>
        <goal>check</goal>
    </goals>
    <configuration>
        <rules>
            <rule>
                <element>PACKAGE</element>
                <limits>
                    <limit>
                        <counter>LINE</counter>
                        <value>COVEREDRATIO</value>
                        <minimum>${code-coverage.line-covered-ratio.min}</minimum>
                    </limit>
                </limits>
            </rule>
        </rules>
    </configuration>
  </execution>

进入你父母的pom。 这样将检查所有模块
