关于android studio编译出错的问题

最近在搞一个android wear项目，之前用的是android studio0.8 beta版，之后用了升级的1.0正式版，因为不能直接升级，我卸了0.8重新装了1.0。重新安装后发现，导入原来的那个android wear项目编译出错了，错误如下：

很是郁闷啊，换了很多种gradle版本，删了引用的包都不行，顺便说下，我用的包是这些

gradle配置如下：

android {

    compileSdkVersion 20

    buildToolsVersion '21.1.2'


    defaultConfig {

        applicationId 'im.kuaipai'

        minSdkVersion 20

        targetSdkVersion 20

        versionCode 1

        versionName '1.0'

    }

    buildTypes {

        release {

            minifyEnabled false

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

            debuggable true

        }

    }

    productFlavors {

    }

}


dependencies {

    compile fileTree(include: ['*.jar'], dir: 'libs')

    // You must install or update the Support Repository through the SDK manager to use this dependency.

    // You must install or update the Support Repository through the SDK manager to use this dependency.

    compile 'com.google.android.gms:play-services-wearable:6.5.87'

    compile 'com.google.android.support:wearable:1.1.0'

    compile 'com.android.support:support-v13:21.0.3'

}

就剩50分了。。。
