Flutter run报错如何解决 Could not find apksig.jar

Question

flutter运行报错，完整提示如下：
（build.gradle和flutter.gradle都改成阿里云了，这个文件在阿里云镜像也能找到）

* Error running Gradle:
ProcessException: Process "C:\Users\Andy\Documents\VSCode\myapp\android\gradlew.bat" exited abnormally:

* What went wrong:
A problem occurred configuring root project 'android'.
> Could not resolve all artifacts for configuration ':classpath'.
   > Could not find apksig.jar (com.android.tools.build:apksig:3.2.1).
     Searched in the following locations:
         https://maven.aliyun.com/repository/google/com/android/tools/build/apksig/3.2.1/apksig-3.2.1.jar

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
