1、根据Flink 的指导，引用下面的Maven
org.apache.flink:flink-walkthrough-datastream-scala:1.13.5

2、然后执行FraudDetectionJob
3、提示如下的错误：
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/flink/streaming/api/functions/source/SourceFunction
4、查找发现是pom文件的问题，把下面的private屏蔽
<!-- This dependency is provided, because it should not be packaged into the JAR file. -->
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-streaming-java_${scala.binary.version}</artifactId>
<version>${flink.version}</version>
<!-- <scope>provided</scope>-->
</dependency>
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-clients_${scala.binary.version}</artifactId>
<version>${flink.version}</version>

</dependency>
