Question

我正在尝试创建一个与BigTable的简单连接，但我认为我的依赖项是不正确的。据我了解，如果我有一个独立的Java应用程序，我唯一需要导入的是bigtable-hbase-1.x，如下所示，但是，似乎不包括一些所需的hbase类。任何援助将不胜感激。

Exception in thread "main" java.lang.IllegalStateException: Could not find an appropriate constructor for com.google.cloud.bigtable.hbase1_x.BigtableConnection
    at com.google.cloud.bigtable.hbase.BigtableConfiguration.connect(BigtableConfiguration.java:114)
    at com.google.cloud.bigtable.hbase.BigtableConfiguration.connect(BigtableConfiguration.java:99)
    at com.example.cloud.bigtable.helloworld.HelloWorld.connect(HelloWorld.java:14)
    at com.example.cloud.bigtable.helloworld.HelloWorld.main(HelloWorld.java:19)

CODE

package com.example.cloud.bigtable.helloworld;

import com.google.cloud.bigtable.hbase.BigtableConfiguration;
import java.io.IOException;

public class HelloWorld {
    private static final String PROJECT_ID = "______";
    private static final String INSTANCE_ID = "_______";

    //private static Connection connection = null;

    public static void connect() throws IOException {
        BigtableConfiguration.connect(PROJECT_ID, INSTANCE_ID);
    }

    public static void main(String[] args) {
        try {
            connect();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
