android - 无法加载类 'com.android.build.gradle.managed.BuildType_Impl

Question

我正在尝试使用 android studio 进行基本的 ndk 实现。现在我无法同步 gradle 我认为 buid.gradle 中缺少一些配置

我收到这个错误

错误:无法加载类“com.android.build.gradle.managed.BuildType_Impl”。此意外错误的可能原因包括:

• Gradle 的依赖项缓存可能已损坏(这有时会在网络连接超时后发生。)重新下载依赖项并同步项目(需要网络)
• Gradle 构建过程(守护进程)的状态可能已损坏。停止所有 Gradle 守护进程可能会解决此问题。停止 Gradle 构建过程(需要重新启动)
• 您的项目可能正在使用第三方插件，该插件与项目中的其他插件或项目请求的 Gradle 版本不兼容。

如果 Gradle 进程损坏，您还可以尝试关闭 IDE，然后杀死所有 Java 进程。

Answer 1

我的问题已解决，解决方案是将“依赖项”置于模型之外{}

proGuard 规则变为

proguardFiles.add(file("proguard-rules.txt"))

代替

proguardFiles += file('proguard-rules.txt')
