I am converting an existing Java library to use module-info.java. I use Lombok and generics extensively. When I run "mvn package" I get a ton of errors that follow this pattern:
[ERROR] /projects/app/src/main/java/com/whatever/app/server/handlers/HandlerCreateForumPost.java:[116,13] cannot find symbol
[ERROR] symbol: method <com.whatever.app.common.messages.CreateForumPostResults>builder()
[ERROR] location: class com.whatever.app.common.Response
The statement that causes the error is:
return Response
.<CreateForumPostResults>builder()
.success(true)
.requestID(context.getRequestID())
.results(
CreateForumPostResults
.builder()
.id(forumPostID)
.build()
)
.build();
Line 116 reported in the error is the one that reads ".builder()".
The Response class lives in com.whatever.app.common and is defined as:
package com.whatever.app.common;
import lombok.Getter;
import lombok.Setter;
import lombok.experimental.SuperBuilder;
import lombok.extern.jackson.Jacksonized;
@SuperBuilder
@Jacksonized
@Getter
@Setter
public class Response<T extends Response.Results> {
boolean success;
String message;
String requestID;
T results;
@SuperBuilder
@Jacksonized
@Getter
@Setter
public static class Results {
}
}
The CreateForumPostResults class lives in com.whatever.app.common.messages and extends Response.Results:
package com.whatever.app.common.messages;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.whatever.app.common.AppResponse;
import lombok.Getter;
import lombok.Setter;
import lombok.experimental.SuperBuilder;
import lombok.extern.jackson.Jacksonized;
import java.util.UUID;
@SuperBuilder
@Getter
@Setter
@Jacksonized
public class AppCreateForumPostResults extends AppResponse.Results {
@JsonProperty("id")
UUID id;
}
My module-info.java looks like this:
module com.whatever.app.common {
exports com.whatever.app.common;
exports com.whatever.app.common.messages;
requires com.fasterxml.jackson.annotation;
requires com.fasterxml.jackson.core;
requires com.fasterxml.jackson.databind;
requires com.fasterxml.jackson.datatype.jsr310;
requires com.google.common;
requires lombok;
}

I suspect that there's some magic incantation needed to make Lombok's @Builder annotation (and possibly others) work with module-info.java, or perhaps something related to generics that is causing this to break, but I haven't been able to figure out what it is.
What am I doing wrong?
Any insights are greatly appreciated.
