Android Room 2.1.0-alpha03 @DatabaseView缺少语法检查和视图名称

Question

我在AndroidX分支上使用roomVersion ='2.1.0-alpha03'

// Room (androidx)
implementation "androidx.room:room-runtime:$rootProject.roomVersion"
implementation "androidx.room:room-rxjava2:$rootProject.roomVersion"
implementation "androidx.room:room-guava:$rootProject.roomVersion"
testImplementation "androidx.room:room-testing:$rootProject.roomVersion"
annotationProcessor "androidx.room:room-compiler:$rootProject.roomVersion"

这是我的@DatabaseView查询：

@DatabaseView("SELECT * FROM DataPointJoin " +
    "INNER JOIN Device ON Device.device_uid = DataPointJoin.device_uid " +
    "INNER JOIN Measurement ON Measurement.measurement_uid = DataPointJoin.measurement_uid " +
    "INNER JOIN Location ON Location.location_uid = DataPointJoin.location_uid " +
    "INNER JOIN User ON User.user_uid = DataPointJoin.user_uid " +
    "INNER JOIN SyncRecord ON SyncRecord.sync_uid = DataPointJoin.uid ")

这是我的用法示例：

@Query("SELECT * FROM DataPoint WHERE DataPoint.uid = :uid")
Flowable<Optional<DataPoint>> get(String uid);

在使用@DatabaseView（）将联接封装到View中时，以及在清理并重建后：

1. 我的@DatabaseView查询没有像在@Query（）中那样被检查或突出显示，只是一个普通的长字符串。
2. 已编译，但是IDE无法解析View符号。
