Error: The apk for your currently selected variant (app-release.apk) is not sign

签名配置：

 signingConfigs {
        debug {
            storeFile file('sign.jks')
            storePassword 'pwd'
            keyAlias 'keyAlias'            keyPassword 'pwd'        }
        release {
            storeFile file('sign.jks')
            storePassword 'pwd'            keyAlias 'keyAlias'            keyPassword 'pwd'        }

    }

问题来了，签名配置是写的好好，但依然提示 Error: The apk for your currently selected variant (app-release.apk) is not sign

就是这里，Android studio 没有给自动配置。
