My android project is “using an old version of the Android Gradle plug-in”

Question

I am getting this error

Project is using an old version of the Android Gradle plug-in. The minimum supported version is 0.6.3.

Please update the version of the dependency 'com.android.tools.build:gradle' in your build.gradle files.

So i did research and realized I had to go to my project build.gradle file and change this part of my dependencies

dependencies {
classpath 'com.android.tools.build:gradle:0.4'
}

but my build.gradle file doesnt have that. This is my build.gradle file

apply plugin: 'android'

 dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
compile project(':Desktop:Coding:SlidingMenu-master:library')
}

android {
compileSdkVersion 19
buildToolsVersion "19.0.0"

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

    // Move the tests to tests/java, tests/res, etc...
    instrumentTest.setRoot('tests')

    // Move the build types to build-types/<type>
    // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
    // This moves them out of them default location under src/<type>/... which would
    // conflict with src/ being used by the main source set.
    // Adding new build types or product flavors should be accompanied
    // by a similar customization.
    debug.setRoot('build-types/debug')
    release.setRoot('build-types/release')
}
}

What am I missing?

EDIT:

updated code

 apply plugin: 'android'

buildscript {
repositories {
    mavenCentral()
}

dependencies {
classpath 'com.android.tools.build:gradle:0.6.4'
compile fileTree(dir: 'libs', include: '*.jar')
compile project(':Desktop:Coding:SlidingMenu-master:library')
}
}


 android {
compileSdkVersion 19
buildToolsVersion "19.0.0"

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

    // Move the tests to tests/java, tests/res, etc...
    instrumentTest.setRoot('tests')

    // Move the build types to build-types/<type>
    // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
    // This moves them out of them default location under src/<type>/... which would
    // conflict with src/ being used by the main source set.
    // Adding new build types or product flavors should be accompanied
    // by a similar customization.
    debug.setRoot('build-types/debug')
    release.setRoot('build-types/release')
}
 }

new error

Answer 1

You are missing a buildscript { ... } block containing the dependencies { classpath ... } block you showed above (and also a repositories { ... } block). Such a block must be available at least in the root project's build script, or apply plugin: "android" won't work.
