如何在Gradle中逐個執行任務

我有這個gradle構建文件。如何在Gradle中逐個執行任務

buildscript { 
    repositories { 
     mavenCentral() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:0.5.+' 
     classpath 'com.eriwen:gradle-css-plugin:1.2.1' 
     classpath 'com.eriwen:gradle-js-plugin:1.5.1' 
    } 
} 

apply plugin: 'android' 
apply plugin: 'js' 
apply plugin: 'css' 

dependencies { 
    compile files('libs/android-support-v4.jar') 
    compile files('libs/cordova-2.7.0.jar') 
    compile files('libs/libGoogleAnalyticsV2.jar') 
} 

task MinifyJSForRelease { 

tasks.add(name:"copyTask2", type:Copy){ 
    from 'assets/' 
    into 'build/minifiedassets/assets' 
} 
it.dependsOn copyTask2 
def tester = fileTree(dir:"build/minifiedassets/assets", include:"**/*.js"); 
println tester 
tester.eachWithIndex {File file, idx -> 
    tasks.add(name: "makeMinifyJS${idx}", type: com.eriwen.gradle.js.tasks.MinifyJsTask) { 
     source = file 
     dest = "${file.path}" 
     closure { 

      compilerOptions.languageIn = "ECMASCRIPT5" 
     } 

    } 
} 

it.dependsOn tasks.matching { Task task -> task.name.startsWith("makeMinifyJS")} 
} 

build.dependsOn MinifyJSForRelease 

android { 
compileSdkVersion 17 
buildToolsVersion "17" 

signingConfigs { 
    release { 
     storeFile file('keystores/mobilecoe_android.keystore') 
     storePassword "mobilecoe" 
     keyAlias "MobileCoE" 
     keyPassword "mobilecoe" 
    } 
} 

defaultConfig { 
    minSdkVersion 10 
    targetSdkVersion 16 
} 
buildTypes { 
    debug { 

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

      instrumentTest.setRoot('tests') 
     } 
    } 

    release { 

     signingConfig signingConfigs.release 
     zipAlign true 
     sourceSets { 
      main { 
       manifest.srcFile 'AndroidManifest.xml' 
       java.srcDirs = ['src'] 
       resources.srcDirs = ['src'] 
       aidl.srcDirs = ['src'] 
       renderscript.srcDirs = ['src'] 
       res.srcDirs = ['res'] 
       assets.srcDirs = ['build/minifiedassets/assets'] 
      } 

      instrumentTest.setRoot('tests') 
     } 
    } 
} 
}

我想要運行一個象的第一件事任務MinifyJSForRelease將資產文件夾複製到，我想，然後這個過程完成之後，當我想要再縮小JS文件。現在，當我運行任務它複製文件夾，但沒有達到結束的下一個功能說，它沒有什麼可以縮小，但如果我第二次運行任務（當文件夾已被複制）它變魔術，並做一切。

我做錯了什麼？我需要：
