java - 如何将 JUnit 5 源导入 Eclipse？

Question

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

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。直到这一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 类文件。关于如何解决这个问题的任何想法？

Answer 1

Eclipse IDE默认不支持编译Kotlin源码。

要使其在 Eclipse 中正常工作，您需要安装 Kotlin Plugin for Eclipse然后右键单击 junit-jupiter-engine 项目并选择“Configure Kotlin/Add Kotlin Nature”。

但是请注意，Eclipse 的 Kotlin 插件众所周知不能在 Eclipse 中始终如一地工作。因此，您可能只是想忽略那些编译器错误(这是我实际做的尴尬)或切换到 IntelliJ IDEA。
