apache flink 无法解析导入 [英] apache flink not able to resolve imports

问题描述

我正在研究 flink 介绍，但我无法正确导入

import org.apache.flink.streaming.api.datastream.DataStream;导入 org.apache.flink.streaming.api.environment.StreamExecutionEnvironment；导入 org.apache.flink.walkthrough.common.sink.AlertSink;导入 org.apache.flink.walkthrough.common.entity.Alert;导入 org.apache.flink.walkthrough.common.entity.Transaction;导入 org.apache.flink.walkthrough.common.source.TransactionSource;

以上这些包无法导入我使用了以下网站

我能够从命令行(通过mvn clean package")构建应用程序，而无需进行任何更改.

解决方案

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.
