如何将 JUnit 5 源导入 Eclipse？

Question

我发现一些关于在我的 Eclipse 中使用 JUnit5 (https://github.com/junit-team/junit5) 的问题 IDE。

PS：我在 Windows 10 中使用 JDK 11 和正确配置的环境文件。在 Eclipse 中也是如此。

我已经完成了这些步骤：

• 分支到我的 github 并将其克隆到我的本地机器。

• 使用git bash进入项目文件夹和./gradlew clean build。直到这部分一切顺利并成功完成。

• 打开 Eclipse 并导入为 Gradle 项目。

• 同步 Eclipse 工作区后，出现错误：

看起来它无法识别项目内置的一些 Kotlin class 文件。关于如何解决这个问题的任何想法？

Eclipse IDE默认不支持编译Kotlin源码

要在 Eclipse 中运行，您需要安装 Kotlin Plugin for Eclipse，然后右键单击 junit-jupiter-engine 项目和 select "Configure Kotlin / Add Kotlin Nature".

但是请注意，Eclipse 的 Kotlin 插件 并非 在 Eclipse 中始终如一地工作。因此，您可能只想忽略那些编译器错误（这是 令人尴尬 我实际做的事情）或切换到 IntelliJ IDEA。
