Question

我去了Windows -> Preferences -> Java -> install JRE's并将我的jdk 10文件放在其中。仍然在那里但未被阅读

我去了computer -> right click properties -> advance systems-> added JAVA_HOME systems variables

我还以->运行配置->环境的身份运行，并尝试将Java 10路径放置在其中，但是在运行弹簧批测试时却出现了错误。

我去过几乎所有地方，都尝试着把Java带回家阅读JDK，但它仍然显示为JRE：

* What went wrong:

编辑：我决定删除Java 1.8，现在将JAVA HOME显示为10，但是它是JRE而不是JDK，我收到一个新错误。（JRE 0和JDK 10都在同一文件夹中）

想出了一个短期解决方案。 JAVA_HOME仍会恢复为JRE，但是如果您单击

> run as -> run configuration -> gradle project, chose your project ->
> Java home -> add your jdk file and click run.

这对我有用。但是当我要进行gradle测试时，我不得不重复这些步骤

Working Directory: C:\Users\git\rxdpf-paymentportalbatchjob
Gradle User Home: C:\Users\.gradle
Gradle Distribution: Local installation at C:\Users\Software\gradle-4.10.2-bin\gradle-4.10.2
Gradle Version: 4.10.2
Java Home: C:\Program Files\Java\jdk-10.0.1
JVM Arguments: None
Program Arguments: None
Build Scans Enabled: false
Offline Mode Enabled: false
Gradle Tasks: testClasses


> Configure project :

Java Home不断恢复为JRE，但我需要JDK
