问题描述
我正在尝试检查JUnit 5的源代码。我在本地计算机上克隆了他们的存储库。 他们的存储库说我需要JDK 11来构建这个项目。但是我尝试使用JDK 14运行它。如果仅在JDK 11上运行，请告诉我。 我从项目的根目录执行了

我需要一些帮助来解决此问题，以便我可以成功地构建项目。
我的系统信息
操作系统：Windows 10
JDK版本：jdk-14.0.2
Gradle版本：Gradle 6.5.1
解决方法
从今天开始，需要JDK 11才能运行JUnit 5的Gradle设置。有关最新说明，请参考https://github.com/junit-team/junit5/#building-from-source。
为了在较新的JDK上构建JUnit 5，除了运行Gradle的JDK 11安装之外，您还需要指定编译源文件时应使用的JDK附加路径。这是在JDK 14、15和16上运行的"cross-version"工作流程的要旨。
