[1.8.9 Forge Gradle] Error Message when I try to reload all Gradle projects (setupDecompWorkspace, recompileMc etc.)

Hello,

Recently, I've been having some issues when trying to make a 1.8.9 Forge Mod, which only started occurring no less than one week ago:

If there's any solution to this, please let me know as I've been struggling to find one for nearly 2 days straight now. Thanks.

My build.gradle:

plugins {
    id 'net.minecraftforge.gradle.forge' version 'FG_2.1-SNAPSHOT'
}

/*
// for people who want stable - not yet functional for MC 1.8.8 - we require the forgegradle 2.1 snapshot
plugins {
    id "net.minecraftforge.gradle.forge" version "2.0.2"
}
*/
version = "1.0"
group= "com.yourname.modid" // http://maven.apache.org/guides/mini/guide-naming-conventions.html
archivesBaseName = "modid"

minecraft {
    version = "1.8.9-11.15.1.2318-1.8.9"
    runDir = "run"

    // the mappings can be changed at any time, and must be in the following format.
    // snapshot_YYYYMMDD   snapshot are built nightly.
    // stable_#            stables are built at the discretion of the MCP team.
    // Use non-default mappings at your own risk. they may not allways work.
    // simply re-run your setup task after changing the mappings to update your workspace.
    mappings = "stable_22"
    // makeObfSourceJar = false // an Srg named sources jar is made by default. uncomment this to disable.
}

dependencies {
    // you may put jars on which you depend on in ./libs
    // or you may define them like so..
    //compile "some.group:artifact:version:classifier"
    //compile "some.group:artifact:version"

    // real examples
    //compile 'com.mod-buildcraft:buildcraft:6.0.8:dev'  // adds buildcraft to the dev env
    //compile 'com.googlecode.efficient-java-matrix-library:ejml:0.24' // adds ejml to the dev env

    // the 'provided' configuration is for optional dependencies that exist at compile-time but might not at runtime.
    //provided 'com.mod-buildcraft:buildcraft:6.0.8:dev'

    // the deobf configurations:  'deobfCompile' and 'deobfProvided' are the same as the normal compile and provided,
    // except that these dependencies get remapped to your current MCP mappings
    //deobfCompile 'com.mod-buildcraft:buildcraft:6.0.8:dev'
    //deobfProvided 'com.mod-buildcraft:buildcraft:6.0.8:dev'

    // for more info...

    // http://www.gradle.org/docs/current/userguide/dependency_management.html

}

processResources
        {
            // this will ensure that this task is redone when the versions change.
            inputs.property "version", project.version
            inputs.property "mcversion", project.minecraft.version

            // replace stuff in mcmod.info, nothing else
            from(sourceSets.main.resources.srcDirs) {
                include 'mcmod.info'

                // replace version and mcversion
                expand 'version':project.version, 'mcversion':project.minecraft.version
            }

            // copy everything else, thats not the mcmod.info
            from(sourceSets.main.resources.srcDirs) {
                exclude 'mcmod.info'
            }
        }

My settings.gradle:

pluginManagement {
    repositories {
        gradlePluginPortal()
        mavenCentral()
        maven {
            name = "sonatype"
            url = "https://oss.sonatype.org/content/repositories/snapshots"
        }
        maven { url "https://maven.minecraftforge.net/" }
        maven { url "https://jitpack.io/" }
    }
    resolutionStrategy {
        eachPlugin {
            switch (requested.id.id) {
                case "net.minecraftforge.gradle.forge":
                    useModule("com.github.asbyth:ForgeGradle:${requested.version}")
                    break
            }
        }
    }
}

The error message whenever I try to do anything (setupDecompWorkspace, recompileMc, genIntellijRuns etc.)
