我创建了一个本机脚本应用程序并尝试使用tns命令构建（tns build android）并面临以下问题：
项目成功准备（android）
Building project...
Gradle build...
+ setting applicationId
+ applying user-defined configuration from C:\project_repo\helper_mobile_app\helper\app\App_Resources\Android\app.gradle
Applying settings from C:\project_repo\helper_mobile_app\helper\app\App_Resources\Android\settings.json
+ adding nativescript runtime package dependency: nativescript-optimized-with-inspector

任务执行失败＆＃39;：app：runSbg＆＃39;。
答案 0 :(得分：0)
我与calander插件的java类未找到错误有相同的问题， 这对我来说很好。
删除node_modules，platforms，hooks文件夹和package-lock.json文件
运行
npm i
重建项目->
tns run android
或
tns build android
