Build failed in IDEA: Failed to apply plugin [id 'net.minecraftforge.gradle.forge']

gradlew idea

 

Still like that

I added something to build.gradle:

Quote

 buildscript {
    repositories {
        jcenter()
        maven { url = "http://files.minecraftforge.net/maven" }
        maven { url = "https://repo1.maven.org/maven2" } // I only added this
    }
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.3-SNAPSHOT'
    }
}
apply plugin: 'net.minecraftforge.gradle.forge'
//Only edit below this line, the above code adds and enables the necessary things for Forge to be setup.
...

There is another one error:

Quote

ERROR: Unable to load class 'com.github.abrarsyed.jastyle.ASFormatter'.
Possible causes for this unexpected error include:
Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)

The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)

Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of >Gradle requested by the project.

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
