使用mvn命令创建Flink Maven项目和”胖JAR“打包

1.使用命令行工具cd到你要创建项目的目录下，然后使用命令行创建Flink Maven Quickstart Scala项目

mvn archetype:generate  \
    -DarchetypeGroupId=org.apache.flink \
    -DarchetypeArtifactId=flink-quickstart-scala    \
    -DarchetypeVersion=1.10.0   \
    -DgroupId=org.apache.flink.quickstart   \
    -DartifactId=flink-scala-project   \
    -Dversion=0.1   \
    -Dpackage=org.apache.flink.quickstart   \
    -DinteractiveMode=false

2.pom.xml文件内容

    4.0.0

    org.apache.flink.quickstart
    flink-scala-project
    0.1

3.这里在本地测试的时候可能会报错

java.lang.NoClassDefFoundError: scala/collection/Seq

需要把pom.xml中的

provided

注释掉，因为provide将不会被打包到lib目录下，所以发生找不到的错误。
4.使用”胖jar“打包

mvn clean package -Pbuild-jar

4.在target文件夹可以看到flink-scala-project-0.1.jar文件，现在可以将jar上传到http://localhost:8081 Submit New job进行测试啦！
