gradle - Java Home不断恢复为JRE，但我需要JDK

Question

我已经转到Windows -> Preferences -> Java -> install JRE's并将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到systems variables
我还以->运行配置->环境的身份运行，并尝试在其中放置Java 10路径，但是在运行Spring Batch测试时却出现了错误。

我去过几乎所有地方，都尝试着去Java读书JDK，但它仍然显示为JRE:

Working Directory: C:\Users\git\paymentportalbatchjob

错误:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.
> Could not target platform: 'Java SE 10' using tool chain: 'JDK 8 (1.8)'.

编辑:我决定删除Java 1.8，现在它显示JAVA HOME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)

新错误:

the according directory.

Answer 1

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.

它对我有用。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 :
createDockerfile
createDockerfile

> Task :bootBuildInfo
> Task :compileJava UP-TO-DATE
> Task :generateGitProperties UP-TO-DATE
> Task :processResources UP-TO-DATE
> Task :classes
> Task :compileTestJava
> Task :processTestResources NO-SOURCE
> Task :testClasses
