Incompatible because this component declares a component compatible with Java 11 and the consumer needed a component compatible with Java 8

[sash-kp]

Hi, We're using Springfox repo which in turn uses grgit as a plugin in its build.gradle like below.

plugins {
...
id "org.ajoberstar.grgit" version "4.0.2"
id "org.ajoberstar.git-publish" version "3.0.0-rc.1"
...
}

gradle version used is : distributionUrl=https://services.gradle.org/distributions/gradle-6.5-bin.zip
java version is : java 8

The Springfox repo used to get complied successfully before , but when we try building it again after 1 or 2 years without any changes , comilation gets failed with below error which mentions about java 8 and java 11 compatibility. Can you please help here how to get it complied successfully using java 8? Because as mentioned, we haven't changed anything in the repo at all. Still the compilation whihc used to work earlier, isn't working now with java 8.
