如何配置 build.gradle 使用 Junit5 和 Jacoco 进行测试覆盖
How to configure build.gradle using Junit5 and Jacoco for test coverage
我正在尝试配置 build.gradle 文件，使其同时支持 Junit 5 和 Jacoco。我之前使用过 useJunitPlatform，但它会产生另一个错误。我也尝试了其他一些方法，但是 none 可以成功生成 Jacoco 报告。然而，这个配置成功地为我生成了 Jacoco 报告，但它也给了我一个例外。下面是我的 build.gradle 文件。

感谢您的帮助！
根据您的错误信息
Caused by: java.lang.IllegalArgumentException: Unsupported class file major version 59
并根据 https://en.wikipedia.org/wiki/Java_class_file
你正在使用 Java 15.
根据https://www.jacoco.org/jacoco/trunk/doc/changes.html
在 JaCoCo 版本 0.8.6
中添加了对 Java 15 的支持
所以要么您不需要 Java 15 并且可以使用更早的版本，例如 11 (LTS)，要么您需要更改
jacoco {
toolVersion = "0.8.5"
在
jacoco {
toolVersion = "0.8.6"
