Library via jitpack.io How to specify Java version 11?

Question

Android

Updated the studio to the polar fox. Accordingly, he advises switching to Gradle 7.0.
I have a library on github.
After upgrading to 7.0.1, gradle stopped building on jitpack

Getting tasks: ./gradlew tasks --all
Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8 -Dhttps.protocols=TLSv1.2

FAILURE: Build failed with an exception.

* Where:
Build file '/home/jitpack/build/api/build.gradle' line: 2

* What went wrong:
An exception occurred applying plugin request [id: 'com.android.library']
> Failed to apply plugin ' com.android.internal.library'.
> Android Gradle plugin requires Java 11 to run. You are currently using Java 1.8.
- changing the IDE settings.
- changing the JAVA_HOME environment variable.
- changing `org.gradle.java.home` in `gradle.properties`.

From the advice that is offered here, in my opinion it should work
- changing `org.gradle.java.home` in `gradle.properties`.

how and what to slip him, so that the maven plugin would work on their server?

They tell you that you need java 11, but you have 8.
Install 11, and don't forget to check that JAVA_HOME points to the correct place (where 11 lies)
