构建失败的android room&eventbus

我接管了一个android项目，我需要修改数据库（至少添加实体和dao）。问题是，只要代码有一点变化，项目就不再“编译”，我就会得到以下错误。


***\app\src\main\java\fr\***\***\syxs\core\App.java:25: error: cannot find symbol

import fr.***.***.syxs.EventBusIndex;
                                ^
  symbol:   class EventBusIndex
  location: package fr.***.***.syxs

eventbusindex类没有生成，因此，我的应用程序不会编译。我想当我在appdatabase类中更改某些内容时，什么都不会失效/更新？
示例：此代码编译（默认代码）

@Database(entities = {
        MessageInbox.class,
        MessageOutbox.class,
        MessagePredefined.class},
        version = 12)
public abstract class AppDatabase extends RoomDatabase {

    public abstract MessageOutboxDao messageOutboxDao();

    public abstract MessageInboxDao messageInboxDao();

    public abstract MessagePredefinedDao messagePredefinedDao();

    ...

这个不行

@Database(entities = {
        MessageInbox.class,
        MessageOutbox.class,
        MessagePredefined.class},
        version = 12)
public abstract class AppDatabase extends RoomDatabase {

    public abstract MessageOutboxDao messageOutboxDao();

    public abstract MessageInboxDao messageInboxDao();

    public abstract MessagePredefinedDao messagePredefinedDao();

    public abstract OtherClassDao foo();

    ...

无论我多么努力地改变数据库的版本，它都不会改变任何东西。我从我的项目中删除了所有的示意图，我试图清理这里和那里。我还在androidstudio上尝试了著名的“失效缓存&重启”，当然没有结果。我在网上到处找，但找不到任何确凿的证据。

我错过了什么？
编辑12/04：
在我的代码中进行了几次更改之后，我注意到问题是根据dao的内容出现的。当它为空时，所有的东西都会编译，但是如果我添加一个方法，编译就会失败。最后，我认为问题更多的是在实体/dao的层次上，但我不知道问题在哪里。
应用程序数据库：

...
public abstract FooDao fooDao();
...

福岛：

import androidx.room.Dao;
import androidx.room.Insert;
import androidx.room.Update;
import androidx.room.Delete;
import androidx.room.Query;

@Dao
public interface FooDao {

    @Insert
    void insert(Foo foo);

    @Update
    void update(Foo foo);

    @Delete
    void delete(Foo foo);

    @Query("SELECT * FROM foo_table WHERE id=:id")
    Foo getFooById(int id);
}

foo公司：

import androidx.room.Entity;
import androidx.room.PrimaryKey;

@Entity(tableName = "foo_table")
public class Foo {

    @PrimaryKey(autoGenerate = true)
    private long id;
    private boolean yes;

    public Foo() {}

    public Foo(long id, boolean no) {
        this.id = id;
        this.yes = no;
    }

    public Foo(boolean no) {
        this.yes = no;
    }

    public boolean getYes() {
        return yes;
    }

    public void setYes(boolean yes) {
        this.yes = yes;
    }
}
