我收到此错误消息：构建：构建失败 --> 运行构建 --> 运行任务 --> :app:processDebugResources --> executeTaskAction。下面显示的代码顺序为：错误消息，然后 build.gradle(Project)，然后 build.gradle(app)。
其他 StackOverflow 用户之前已多次回答过此错误消息，但他们提出的解决方案均不适合我。主要是因为他们使用的版本建议我修复 build.gradle(Project:app) 中的“com.android.support:appcompat-v7:28.0.0”设置，但他们有不同的版本，因为这些帖子来自 2+几年前。我尝试过清理项目、清理构建、重建构建和项目、添加“Maven”存储库、重新安装所有 Sdks...在过去三个小时内没有任何效果。
这是错误消息：
