我一直在努力解决Android Room组件的问题，
我所做的就是将Android Studio从3.3升级到3.4.1，同时完成了gradle等更改。
我什至尝试回到3.3，但没有任何效果。
我已经使用Run with --info or --debug option来尝试查看更多详细信息，但是没有任何信息可以为我提供更多信息。请帮助

从最初的查找中，您的某些依赖项很旧。请尝试由我运行并测试的以下设置。
Android Studio：3.4.1
build.gradle（项目）
dependencies {
classpath 'com.android.tools.build:gradle:3.4.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.31"
classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.1.0-alpha05"
classpath 'com.google.gms:google-services:4.2.0'
}

}

答案 1 :(得分：1)
您已注释掉room-ktx依赖性，但是我认为您没有更改实际的实现。该依赖关系并未删除，而是重命名为implementation 'androidx.room:room-ktx:' + room_version
。因此，只需添加它以启用对 Room 的 Coroutine 支持。
ALG(m,n)
1. if m > n then
2. return ALG(m - n, n)
3. else if n > m then
4. return ALG(n, m)
5. else
6. return n
答案 2 :(得分：1)
让我们考虑尝试以下方法：
使用以下内容删除与房间相关的所有依赖关系，这些依赖关系是最新的：The Room Documentation
implementation 'androidx.room:room-common:2.1.0'
implementation 'androidx.room:room-compiler:2.1.0'
implementation 'androidx.room:room-runtime:2.1.0'
要考虑的第二件事是您正在复制具有不同版本的依赖项，当构建系统尝试执行其依赖项解析并导致误导性错误时，您可能会遇到问题，例如：
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0-alpha01'
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.0.0'
一个就足够了，最好是稳定的。
如果您需要有关依赖项的信息，并将它们也迁移到androidx here is the migrating to androidx guide

对于所有无法在此处编译的用户来说，这是一个小工作（希望是临时的）。
如果您将gradle版本切换回3.3.2，则android studio应该会像平常一样编译，您可以保留所有其他依赖关系，也可以对其进行更新。
该设置对我有用：
dependencies {
classpath 'com.android.tools.build:gradle:3.3.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:4.3.0'
classpath "org.jfrog.buildinfo:build-info-extractor-gradle:4.9.0"
classpath 'io.fabric.tools:gradle:1.+'
}

我遇到了同样的问题，将OP的gradle文件与我的gradle文件进行比较，发现两者都包含
configurations {
cleanedAnnotations
compile.exclude group: 'org.jetbrains', module: 'annotations'
}
通过删除它，Room的注释处理开始工作。

尝试将会议室版本更新为“ 2.1.0-rc01”。
def room_version = "2.1.0-rc01"
答案 6 :(得分：0)
我遇到了同样的问题，我可以通过更新数据库版本来解决它：
@Database(
entities = [...],
version = 4, exportSchema = true
)
问题是因为自动生成的架构是另一个解决方案，它可能是删除项目中schemas文件夹中的旧架构，但是如果您的应用正在生产中，可能会造成一些麻烦。
答案 7 :(得分：0)
存在相同的问题，并且在依赖项下存在以下注释排除项（不知道为什么）
configurations {
compile.exclude group: 'org.jetbrains', module: 'annotations'
}
将其删除并成功运行。也许对您有帮助？
答案 8 :(得分：0)
有同样的问题。
从我的github上获取项目后发生。
依赖项/版本更改无效。
我所做的是删除了GitHub上除主要分支之外的所有分支，并从其余分支创建了新项目。
问题开箱即用。
答案 9 :(得分：0)
您必须包括该库：
implementation org.jetbrains:annotations-java5:19.0.0
由于通过kapt插件通过注释生成的代码，因此使用org.jetbrains.annotations.NotNull注释。
如果您将生成的Java类复制粘贴到您的类路径中，则会看到编译错误。
