在今天的会议上，我们将介绍一个项目，该项目将实现以下目标：下载与专业相关的元数据，并在会议纪要中记录错误： 无法解析“”的依赖项：app@debugAndroidTest/compileClasspath'：无法解析com.readystatesoftware.sqliteasset:sqliteassethelper:+。，porém atéontem tudo estava函数异常。我有一个小问题

Acredito que o erro esteja relacionado com o compile com.readystatesoftware.sqliteasset:sqliteassethelper:+

buildscript {

    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

换行

实现'com.readystatesoftware.sqliteasset:sqliteassethelper:+'

到
