flink_根据官网搭建项目_DataStream API

1 遇到的错误

• 运行时会报类找不到:将pom.xml中的<scope>provided</scope>注释掉即可,还有一种办法,见官方说明

• 构建时报错: Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.1.2:generate

使用 mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate 替换   mvn archetype:generate

• 在github中删掉之前创建失败的仓库,进入仓库的settings,拉到最底部

 

•  重新提交项目到github
