IDEA学习Flink源码

一、git下载源码

?

1	git clone https://github.com/apache/flink.git

二、编译Flink

1.修改maven setting.xml, 便于尽量下载依赖包和插件

https://github.com/PanicJaw/FlinkConf/blob/master/settings.xml

2.编译

?

1	mvn clean install -DskipTests

3.出现问题

?

1 2	[ERROR] Failed to execute goal org.apache.rat:apache-rat-plugin:0.12:check (default) on project flink-parent: Too many files with unapproved license: 1793 See RAT report in: /Users/zhuangzebo/IdeaProjects/flink/target/rat.txt -> [Help 1] [ERROR]

原因：新加的文件没有添加license头

解决：添加-Drat.skip=true参数，跳过license检测
