Android Gradle 问题：原因：groovy.lang.MissingMethodException：没有方法签名

Question

我的项目永远不会建设。 我一直都遇到同样的错误。

我尝试了一天的其他解决方案，但我无法取得进展：/

我搜索了解决方案，我意识到它可能与 maven 有关。

顺便说一句，我的项目很旧。

这里是错误信息；

在此处输入图像描述

Caused by: groovy.lang.MissingMethodException: No signature of method: build_1tiyt7a69ra5smonjfai0v39h.android() is applicable for argument types: (build_1tiyt7a69ra5smonjfai0v39h$_run_closure2) values: [build_1tiyt7a69ra5smonjfai0v39h$_run_closure2@2cca4753]
at build_1tiyt7a69ra5smonjfai0v39h.run

我的build.gradle (app)文件如下。

感谢您的帮助

Answer 1

如果您最近对 proguard 进行了一些更改。 查找设置useProguard false/true 的行并删除它，因为它不再受支持
