gradlew build Error

I'm new here and working with the new MCreator (only 2 days), it was working properly but suddenly there was a problem building the mods and can't fix it.

I had made one mod normally and not know what it happened to appear this problem. Please I need help to continue learning in the creation of mods

That's my gradlew build :

buildscript {
    repositories {
        mavenCentral()
        maven {
            name = "forge"
            url = "http://files.minecraftforge.net/maven"
        }
        maven {
            name = "sonatype"
            url = "https://oss.sonatype.org/content/repositories/snapshots/"
        }
    }
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:1.2-SNAPSHOT'
    }
}

apply plugin: 'forge'      <<<<<<<  THIS IS THE LINE 18  >>>>>>>

version = "1.0"
group = "com.yourname.modid" // http://maven.apache.org/guides/mini/guide-naming-conventions.html

minecraft {
    version = "1.7.10-10.13.4.1614-1.7.10"
    runDir = "eclipse"
}
