Gradle - Could not target platform: 'Java SE 8' using tool chain: 'JDK 7 (1.7)'

Question

I am trying to import Gradle project in Intellij Idea with local Gradle distrib and getting stacktrace with the following message: Could not target platform: \'Java SE

Answer 1

And so I see from other answers that there are several ways of dealing with it. But I don't believe this. It has to be reduced into one way. I love IDE but, but if I follow the IDE steps provided from different answers I know this is not the fundamental algebra. My error looked like:

* What went wrong:
Execution failed for task ':compileJava'.
> Could not target platform: 'Java SE 11' using tool chain: 'JDK 8 (1.8)'.

And the way to solve it scientifically is:

vi build.gradle

To change from:

java {
    sourceCompatibility = JavaVersion.toVersion('11')
    targetCompatibility = JavaVersion.toVersion('11')
}

to become:

java {
    sourceCompatibility = JavaVersion.toVersion('8')
    targetCompatibility = JavaVersion.toVersion('8')
}

The scientific method is that method that is open for argumentation and deals on common denominators.
