问题原因

1. 这个错误表示项目引入的依赖 FingerPaintView 无法从当前的配置的仓库中找到，即无法从阿里云 Maven 仓库、Google Maven 仓库、Maven Central 仓库中找到

2. FingerPaintView 是一个 GitHub 上的依赖，需要在项目中添加 JitPack 仓库

3. JitPack 是专门用来拉取 GitHub（以及 GitLab、Bitbucket 等）上开源项目作为依赖的仓库服务

处理策略

• 在 settings.gradle 文件中添加 JitPack 仓库

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        ...

        maven { url 'https://jitpack.io' }
    }
}
