所以，我遇到了这个问题，每次我尝试从 Eclipse 运行 Gradle 时都会出现这个错误:

Working Directory: C:\Users\Owen\eclipse-workspace\SimpleMultiplycationProgram\SimpleMultiplycationProgramApp
Gradle user home: C:\Users\Owen\.gradle
Gradle Distribution: Gradle wrapper from target build
Gradle Version: 4.3.1
Java Home: C:\Program Files\Java\jre1.8.0_251
JVM Arguments: None
Program Arguments: None
Build Scans Enabled: false
Offline Mode Enabled: false
Gradle Tasks: run

:SimpleMultiplycationProgramApp:compileJava FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':SimpleMultiplycationProgramApp:compileJava'.
> Could not find tools.jar. Please check that C:\Program Files\Java\jre1.8.0_251 contains a valid JDK installation.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

* Get more help at https://help.gradle.org

BUILD FAILED in 13s
1 actionable task: 1 executed

所以，我开始尝试解决这个问题，但是所有的 stackoverflow 问题和教程都说要执行类似运行 ./gradle biuld 的操作。它给了我这个错误(来自cmd):

'.' is not recognized as an internal or external command,
operable program or batch file.

`/gradle biuld' 给了我:

'/gradle' is not recognized as an internal or external command,
operable program or batch file.

和 gradle biuld给我:

'gradle' is not recognized as an internal or external command,
operable program or batch file.

而 C:\Users\Owen.gradle 是一个文件夹，那么这是怎么回事呢？

这似乎是关于两个不相关的问题。一方面，您的 PATH 上似乎没有 gradle，因此无法识别该命令。然后您还缺少 rt.tools。看看有没有this other question帮你解决。您似乎只下载了 JRE 而没有下载 JDK。
