codegen project is incomplete / non-functional

[Marcono1234]

It looks like the codegen project is incomplete. The only thing it does is write an empty class, see:

gson/codegen/src/main/java/com/google/gson/codegen/GeneratedTypeAdapterProcessor.java

Lines 56 to 58 in a92bbf8

	writer.addPackage(CodeGen.getPackage(type).getQualifiedName().toString());
	writer.beginType(typeAdapterName, "class", FINAL, null);
	writer.endType();

For example, the output for the Order test class is just:

package com.google.gson.codegen.functional;
final class Order$TypeAdapter {
}

Should the project be removed, or should its functionality be implemented eventually?

I think I would be in favour of deleting it. The code is 9 years old. It seems very half-baked, has no documentation, and has what appears to be a copy of a very old version of JavaPoet. There might be interest in some sort of code-generating solution, but if so I think it would be better built with modern tools, including the latest JavaPoet.

Perhaps @inder123 wants to weigh in, though?

proto has users. May be best to leave it as is?

[eamonnmcmanus]

Yes, sorry, the question was about the codegen project, not the proto project.
