--------------------------------------
[~lindong] Currently, 1.8 is still good enough to build Flink from source with
Java 8 in my computer [1].

> Set requireJavaVersion in pom.xml to be at least 11

> Flink 1.15 and later versions require at least Java 11 to build from sources
> [1]. However, if users build Flink with Java 1.8 using the following command,
> the build would fail due to org.apache.maven.plugin.MojoExecutionException
> without mentioning the Java version issue.
>
> {code:bash}
> mvn clean install -DskipTests -Pskip-webui-build
> {code}
>
> We should update the required JDK version in pom.xml so that `mvn install`
> will report error directly related to the JDK version if users's JDK version
> is below 11.
