我正在尝试使用 DBFlow 库进行数据库设计。之后，从网络上设置所有东西，编译时我在 Gradle 中遇到错误。

错误：

我在我的项目中使用 ForeignKeys，但我不知道这是否是问题所在。我放了两张桌子，看看我做得好不好。

卡车实体

@ModelContainer
@Table(database = AppDatabase.class)
public class mTruck extends BaseModel {

    @PrimaryKey(autoincrement = true)
    long _id;

    @Column
    long id;

    @Column
    String license;

    @Column
    @ForeignKey(references = {@ForeignKeyReference(columnType = Long.class, columnName = "creationDate", foreignKeyColumnName = "_id")})
    mDate creationDate;

    @Column
    @ForeignKey(references = {@ForeignKeyReference(columnType = Long.class, columnName = "modificationDate", foreignKeyColumnName = "_id")})
    mDate modificationDate;

    @Column
    @ForeignKey(references = {@ForeignKeyReference(columnType = Long.class, columnName = "vModelo", foreignKeyColumnName = "_id")})
    mModel vModel;

日期实体

ModelContainer
@Table(database = AppDatabase.class)
public class mDate extends BaseModel {

    @PrimaryKey(autoincrement = true)
    long _id;

    @Column
    @ForeignKey(references = {@ForeignKeyReference(columnType = Long.class, columnName = "timezone", foreignKeyColumnName = "_id")})
    mTimezone timezone;

    @Column
    int offset;

    @Column
    long timestamp;

}

我不知道我做错了什么。你能帮我解决这个问题吗？

谢谢。

我刚刚找到了解决方案。显然这是库的 master 分支的问题，它解决了在 Gradle 中更改编译分支的依赖关系：

dependencies {
    apt 'com.github.Raizlabs.DBFlow:dbflow-processor:3.0.0-beta1'
    compile "com.github.Raizlabs.DBFlow:dbflow-core:3.0.0-beta1"
    compile "com.github.Raizlabs.DBFlow:dbflow:3.0.0-beta1"
  }

至

dependencies {
    apt 'com.github.Raizlabs.DBFlow:dbflow-processor:develop-SNAPSHOT'
    compile "com.github.Raizlabs.DBFlow:dbflow-core:develop-SNAPSHOT"
    compile "com.github.Raizlabs.DBFlow:dbflow:develop-SNAPSHOT"
  }
