Can't start gradle

I've tried a lot of different things like gradle update but I can't seem to fix this issue. I cannot start gradle:

./gradlew build --stacktrace
:......
:app:compileDebugJava

This is my app> gradle.build

apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion "21.0.2"


    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src/main/java']
            resources.srcDirs = ['src/main']
            //aidl.srcDirs = ['src/main']
            renderscript.srcDirs = ['src/main']
            res.srcDirs = ['src/main/res']
            //assets.srcDirs = ['assets']
        }
    }
    productFlavors {
    }
}

dependencies {
    compile 'com.android.support:support-v4:+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

      

        
        
        
      

    

This is my root> gradle.build

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.13.3'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

      

        
        
        
      

    

I also tried doing this tutorial but it didn't work for me: Gradle doesn't work: Execution failed for task: MyApp: compileDebug
