build gms failed in jdk1.8

[LittleBird0616]

When I try to build the gms service in the jdk1.8 environment, I get the following error message：
D:\0Code\99.openSource\datahub-0.12.0\buildSrc\src\main\java\io\datahubproject\OpenApiEntities.java:281: error: incompatible types: inference variable T has incompatible bounds .collect(Collectors.toSet()); ^ equality constraints: String lower bounds: Object where T is a type-variable: T extends Object declared in method <T>toSet()
This error is not reported in JDK11.

But，according to https://github.com/datahub-project/datahub/tree/master/metadata-service#pre-requisites
JDK 1.8 is supposed to work properly.

@LittleBird0616 looks like those docs are outdated. We require Java 17.

I'll fix the docs shortly.

It seems that gms cannot be built using jdk17 until version 0.12.1. (The lombok version is earlier and does not adapt to the JDK of a later version.) Will the new version support JDK17? When will the new version be released?

The next release (0.13.0) will require JDK 17. I can't give a hard timeline, but we'll probably be releasing it in the next few weeks.
