Maven Archetype
类似Spring project initializer ，根据配置向导可以生成maven的project sketch，这个模版中定义了pom文件和项目结构，java 代码的demo， 和编译运行所需要的基本的依赖等。
Flink Maven Archetype
https://ci.apache.org/projects/flink/flink-docs-release-1.12/try-flink/datastream_api.html
Flink 官方文档的例子中介绍了使用例子的Flink Maven Archetype 生成工程结构的模版如下：
mvn archetype:generate \
-DarchetypeGroupId=org.apache.flink \
-DarchetypeArtifactId=flink-walkthrough-datastream-java \
-DarchetypeVersion=1.12.0 \
-DgroupId=group \
-DartifactId=arti \
-Dversion=0.1 \
-Dpackage=demo \
-DinteractiveMode=false
生成的项目结构如下
./
├── pom.xml
└── src
└── main
├── java
│ └── demo
│ ├── FraudDetectionJob.java
│ └── FraudDetector.java
└── resources
└── log4j2.properties

记得Spark也有这种制作好的 maven archetype，官网上没搜到，可以看看这个
