Flink Compile Error Static methods in interface require -target:jvm-1.8

Hi, all

I want to upgrade my flink to 1.12.0. I used the new API for watermark.

I got an error when I compiled my jar.

My pom file content is this.

My JDK version is this.

Can anyone help me with this?

Sincerely

You have to configure the scala-maven-plugin to compile to java 8.

Add this to the configuration of the plugin:

<arg>-target:jvm-${target.java.version}</arg>
