我在Ubuntu版本22.04.2上使用VSCode，根据https：//docs.griddb.net/gettingstarted/java/#schema-creation上的GridDB文档实现和运行一些测试，但由于以下错误，我无法运行代码：

“无法解析导入com.toshiba-Java”

我的Java文件是：

import com.toshiba.mwcloud.gs.*;

public class GridDbTests{
    public static void main(String[] args)
    {
        Properties props = new Properties();
        props.setProperty("notificationAddress", "239.0.0.1");
        props.setProperty("notificationPort", "31999");
        props.setProperty("clusterName", "defaultCluster");
        props.setProperty("user", "admin");
        props.setProperty("password", "admin");
        GridStore store = GridStoreFactory.getInstance().getGridStore(props);
    }
}

lauch.json文件是：

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "java",
            "name": "GridDbTests.java",
            "request": "launch",
            "mainClass": "GridDbTests"
        }
    ]
}

我做错了什么？
