android - 在项目':app'上找不到属性'release'错误

我正在我的应用程序中实现材料设计。
我收到错误消息“错误：（2，0）在项目'：app'上找不到属性'release'。”在建立我的gradle时

这是我的gradle代码：

      apply plugin: 'com.android.application'
      name=release
      storeFile=null
      storePassword=null
      keyAlias=null
      keyPassword=null
      storeType=null

      android {
         compileSdkVersion 21
         buildToolsVersion "21.1.1"

      defaultConfig {
         applicationId "com.rey.material.demo"
         minSdkVersion 9
         targetSdkVersion 21
         versionCode 5
         versionName "0.0.5"
      }

      signingConfigs {
        release {
           storeFile file(MATERIAL_KEYSTORE_FILE)
           storePassword MATERIAL_KEYSTORE_PASSWORD
           keyAlias MATERIAL_KEYSTORE_ALIAS
           keyPassword MATERIAL_KEYSTORE_PASSWORD
        }
      }

      buildTypes {
        release{
           minifyEnabled true
           proguardFiles getDefaultProguardFile('proguard-android.txt'),proguard-rules.pro'
        signingConfig signingConfigs.release
        }
     }
  }

     dependencies {
       compile fileTree(dir: 'libs', include: ['*.jar'])
       compile 'com.android.support:appcompat-v7:22.2.0'
       compile 'com.android.support:cardview-v7:22.2.0'
       compile 'com.squareup.picasso:picasso:2.5.0'
       compile 'com.squareup.leakcanary:leakcanary-android:1.3.1'
       compile project(':lib')
     }

请帮我，
谢谢。

最佳答案

您实际上不需要以下代码

      name=release
      storeFile=null
      storePassword=null
      keyAlias=null
      keyPassword=null
      storeType=null

删除这些行，然后再次检查！
现在应该看起来像这样

apply plugin: 'com.android.application'

      android {
         compileSdkVersion 21
         buildToolsVersion "21.1.1"

      defaultConfig {
         applicationId "com.rey.material.demo"
         minSdkVersion 9
         targetSdkVersion 21
         versionCode 5
         versionName "0.0.5"
      }

      signingConfigs {
        release {
           storeFile file('MATERIAL_KEYSTORE_FILE_Path')
           storePassword 'password'
           keyAlias 'keyAliasName'
           keyPassword 'MATERIAL_KEYSTORE_PASSWORD'
        }
      }

      buildTypes {
        release{
           minifyEnabled true
           proguardFiles getDefaultProguardFile('proguard-android.txt'),proguard-rules.pro'
        signingConfig signingConfigs.release
        }
     }
  }

     dependencies {
       compile fileTree(dir: 'libs', include: ['*.jar'])
       compile 'com.android.support:appcompat-v7:22.2.0'
       compile 'com.android.support:cardview-v7:22.2.0'
       compile 'com.squareup.picasso:picasso:2.5.0'
       compile 'com.squareup.leakcanary:leakcanary-android:1.3.1'
       compile project(':lib')
     }
