Question

我已经关注了多Maven模块的应用程序，并且按照此处https://github.com/jacoco/jacoco/wiki/MavenMultiModule的步骤进行操作，以在测试模块中生成合并的jacoco单元测试覆盖率报告。但是，我们有一项政策强制执行最低总覆盖率的80％，否则构建会失败。这在单个模块应用程序中完美运行。但是，我无法在多模块应用程序的总体覆盖范围上强制执行此操作。任何建议，将不胜感激。

Parent-
-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，但干净安装成功，没有任何覆盖错误。

如果总覆盖率不是80％，我希望mvn全新安装会引发错误

Answer 1

您仅在 test 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>

进入您的父pom。这样，将检查所有模块。
