我有一个项目，里面有Kotlin和Java源文件夹，还有Kotlin和Java测试源文件夹，但当我试图检查覆盖率时，Jacoco找不到Kotlin类的覆盖率。 但是当我尝试检查覆盖率时，Jacoco找不到Kotlin类的覆盖率。
@Godin 我尝试应用 build-helper-maven-plugin 从你的回答来看 对答如流 以增加更多的sourcetest目录，但结果还是 "违反了KotlinExample类行覆盖率为0.0的规则..."
更新 只有当我从Java测试中覆盖Kotlin类时，覆盖才会有效。但从Kotlin的测试中，这是不工作的。
非常感谢任何帮助。

如果你使用的是0.8.3或类似版本的jacoco-maven-plugin，请确保定义了数据文件，并使用下面的配置为插件服务。
<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>
该代码保证了17%的整体覆盖率。
请用以下方法验证
mvn清洁验证
并在配置清单中添加以下内容。
