Question

When i import my Gradle Java project with Intellij Idea i get error

The project uses Gradle 2.12 which is incompatible with IDEA running on Java 10 or newer.

My Intellij Idea version is

IntelliJ IDEA 2019.2 (Community Edition)
Build #IC-192.5728.98, built on July 23, 2019
Runtime version: 1.8.0_211-b12 amd64
VM: Java HotSpot(TM) 64-Bit Server VM by Oracle Corporation
Linux 4.15.0-20-generic
GC: ParNew, ConcurrentMarkSweep
Memory: 1956M
Cores: 4
Registry: git.explicit.commit.renames.prohibit.multiple.calls=false
Non-Bundled Plugins: 

How to fix this issue?

Answer 1

If IDEA still uses Java10 and above after startup, it is probably because IDEA comes with a higher version of Java. Solution: Rename the jbr directory in the IDEA installation directory.

Answer 2

On Intellij press Ctrl+shift+a -> Choose Runtime ->choose JDK version

If you don't see the option, then download and install "Choose Runtime"(https://plugins.jetbrains.com/plugin/12836-choose-runtime) from Marketplace

Answer 3

JetBrains promised to fix in version 2020.1.1 : https://youtrack.jetbrains.com/issue/IDEA-237220

Answer 4

I have found a solution for this. On Intellij press Ctrl+shift+a -> Switch Boot JDK ->choose JDK version

Another solution is use Intellij Utimate Edition. Choose file/Setting and configure Gradle and Java version

Answer 5

In case if you didn't find switch boot JDK option in IDEA you can use
"choose runtime" plugin.

if you want it in action, try Ctrl + shift + A then type choose runtime , in the dialog choose run time select the runtime you want.
