apache flink not able to resolve imports
问题
嗨，我正在学习 Flink 的介绍，但是我无法正确导入以下这些包：
import org.apache.flink.streaming.api.datastream.DataStream;
import org.apache.flink.streaming.api.environment.StreamExecutionEnvironment;
import org.apache.flink.walkthrough.common.sink.AlertSink;
import org.apache.flink.walkthrough.common.entity.Alert;
import org.apache.flink.walkthrough.common.entity.Transaction;
import org.apache.flink.walkthrough.common.source.TransactionSource;
上述的这些包无法导入。
我是从这个链接 [1] 上获取的信息。
在这个链接中，我通过 mvn 命令导入了项目。
请帮我解决这个问题。

在我的IDE（IntelliJ）中尝试后，我发现要想运行该应用程序，我必须在“Run / Edit Configurations”下选择“包括具有“Provided”范围的依赖项”选项。一旦我这样做了，一切都正常工作了。
我能够在命令行中构建该应用程序（通过“mvn clean package”）而不需要进行任何更改。
英文:
I just tried this myself, and found that in order to run the application in my IDE (IntelliJ) I had to select the option under Run / Edit Configurations to 'Include dependencies with "Provided" scope'. Once I did that, everything worked fine.
I was able to build the application from the command line (via "mvn clean package") without making any changes.
