构建应用程序包保护错误

Question

当我尝试使用 android studio 3.2 Canary 17 构建应用程序捆绑包时，我收到以下错误消息。 我不知道缺少什么尖括号浏览了我所有的ProGuard文件，一切似乎都很好，并且可以在旧版本的Android Studio中工作。 gradle build tools 是 com.android.tools.build：gradle：3.2.0-alpha17，distribution url 是 distributionUrl=https：//services.gradle.org/distributions/gradle-4.6-all.zip

Answer 1

该错误是由于城市飞艇与 Gradle 插件 3.2.0 及更高版本的保护不兼容，并已在城市飞艇 9.1.1 中修复(根据更新日志(。只需将您的依赖项更新到 Urban Airship 9.1.1 或更高版本，错误就会消失：

implementation 'com.urbanairship.android:urbanairship-gcm:9.1.1'

Answer 2

错误可能是由项目依赖项之一中定义的规则引发的。就我而言，罪魁祸首是城市飞艇(v9.1.0，已弃用(;升级到 v9.3.2 解决了该问题。
