我的项目包含 Kotlin 和 Java 源文件夹以及 Kotlin 和 Java 测试源文件夹。但是当我尝试检查覆盖范围时，Jacoco 找不到 Kotlin 类的覆盖范围。
@Godin 我尝试从您的答案中应用 build-helper-maven-plugin answer on similar problem用于添加更多源/测试目录，但结果是相同的“所覆盖的 KotlinExample 类行违反的规则是比率 0.0...”
更新 仅当我从 Java 测试中覆盖 Kotlin 类时，覆盖才有效。但从 Kotlin 的测试来看，这是行不通的。
非常感谢任何帮助。

最佳答案
如果您使用0.8.3或类似版本的jacoco-maven-plugin，请确保定义了数据文件，并为插件使用以下配置。
<execution>
<id>jacoco-check</id>
<goals>
<goal>check</goal>
</goals>
<configuration>
<dataFile>${project.build.directory}/coverage-reports/jacoco.exec</dataFile>
<rules>
<rule>
<element>BUNDLE</element>
<limits>
<limit>
<counter>INSTRUCTION</counter>
<value>COVEREDRATIO</value>
<minimum>0.17</minimum>
</limit>
</limits>
</rule>
</rules>
</configuration>
</execution>
此代码可确保总体覆盖率达到 17%。
请使用以下内容验证这一点
mvn 干净验证
命令。 并将其添加到配置 list
<configuration>
<excludes>
<exclude>META-INF/**</exclude>
</excludes>
</configuration>
