Answer 1

我在 app/build.gradle 中做了以下更改

已删除

# 'clean' is already a git command, so we'll use another alias :
$ git config --global alias.clean-repo '! git fetch -p origin && git branch -r ...'

# with this alias on, you can invoke it using :
$ git clean-repo

# this will also work from within 'find ... -exec <command>' :
$ find ... -exec git clean-repo

另外，需要在 pubspec.yaml 中匹配您的依赖项

任务“:app:checkReleaseDuplicateClasses”执行失败。颤动
