android - 任务之间的 Gradle 依赖关系

Question

因此，自从添加了新的 Room android 架构库后，这种情况就开始发生了。我遇到了 AppDatabase_Impl 不存在的问题，我通过将 kapt 添加到注释中来解决这个问题:

• Android Room Persistences library and Kotlin
• Room Persistence lib implementation in Kotlin
• Room Persistence lib implementation in Kotlin(Gradle error)

我怀疑是由 AS、Kotlin 和 Java 8 引起的其他错误，因此我尝试更新到 AS 3.0

我现在在尝试构建时收到以下错误:

Information:Gradle tasks [:app:generateDebugSources,     :app:generateDebugAndroidTestSources, :app:mockableAndroidJar, :app:compileDebugSources, :app:compileDebugAndroidTestSources, :app:compileDebugUnitTestSources, :cryptocurrency-icons:generateDebugSources, :cryptocurrency-icons:mockableAndroidJar, :cryptocurrency-icons:generateDebugAndroidTestSources, :cryptocurrency-icons:compileDebugSources, :cryptocurrency-icons:compileDebugUnitTestSources, :cryptocurrency-icons:compileDebugAndroidTestSources]

请查看this . 看起来这是 Kotlin Gradle 插件 1.1.2-4 中的一个错误
