IntelliJ/Gradle Could not determine java version from '11.0.1'

Question

I'm running a Linux Ubuntu 18 OS. Installed jdk in a custom local directory.

Normally, IntelliJ recommends that you use the default gradle wrapper. But in my case, I want to be able to change the Gradle Version on the fly whenever it's due for an update. If you use IntelliJ with Gradle, and you bump into the following error:

Could not determine java version from '11.0.1'

Answer 1

If you use IntelliJ

Checks:

1. Navigate to:

   File >> Settings >> Build, Execution, Deployment >> Build Tools >> Gradle.

   Alongside Gradle JVM: make sure you select the correct version of Java.

2. Navigate to: Right-Click 'Project Root Directory' & Select Open Module Settings. Project Structure windows shows-up. Make sure your JDK home path is added to the Platform Settings >> SDKs : JDK home path

3. Still, on the same window Project Structure, select correct SDK relevant to your project under

   Project Settings >> Modules : Module SDK

4. Fix/Solution: Nvavigate to & open: gradle/wrapper/gradle-wrapper.properties & update the distributionUrl version to the latest version. In my case (at the time of this post), my older version was:

   distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-bin.zip

   And my latest version is:

   distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-bin.zip

   As shown below:

   

5. In your build.gradle file make sure you set:

   sourceCompatibility = 11

Answer 2

If you are using the latest version of intellijIdea.

In my case, 2019.1 -version

Delete the directory idea's jdk

then RESTART idea.

Hope this is working for you !

In chinese:

(If you can't read chinese,you needn't to read this.All you need to know have typed above already)

如果你是用最新版本的intellijidea.由于intellijidea默认安装了11的java。而且就算你输入java -verison,告诉你是java8，在ide里面也配置了java 8 idea还是告诉你这个错误。

只有通过删除idea自己下载java11版本，可以解决这个问题。直接删除应用包下的jdk文件夹，重启idea就可以。如下图。
