@Builder annotation causes compile error with Java 11

[jrmyr]

Hello!

My code using the @Builder annotation does not compile with Java 11 (or Java 10) while it compiles properly with Java 8.
As issue #1896 was closed and I could not reopen it, I create this issue to provide the code; please see here: https://github.com/jrmyr/lombokbuilder.

To reproduce the problem, just clone the repo and execute a simple gradle compileJava in it. Depending on the Java version in use, it will pass (8) or fail (10, 11). Tested on Mac.

Please tell me if you need more info.
Thanks.

Can you try to assign the result of the build method to a local variable first?

I don't know if we can configure the issue tracker to allow reopening by the reporter.

I just found out that even the reporter cannot open an issues that they didn't close themselves.

No problem. Creating a new one and linking the old one is not an issue for me.

I tried this but the behavior did not change. I updated the github repo with my changes.
Please tell me should I miss and/or misunderstand something.

It seems this issue is similar to #1877.
I checked with maven and with maven the project compiles under Java 8, 10 and 11.
So, seems gradle-specific.

EDIT: Sorry, I tried again with the project as a clean new maven project: I get the same error as well. So, maven is also affected and it's not gradle specific.
Sorry again for this misinformation and all this confusion.

Here's a real simple test case for it:

class BuilderOnConstructor {
	@lombok.Builder
	BuilderOnConstructor(int a, boolean b) {}

	static class BuilderOnConstructorBuilder {
		void from() {
			a(x()).b(y());
		}
	}

	static int x() {
		return 0;
	}

	static boolean y() {
		return true;
	}
}

confirmed failure with error: BuilderOnConstructor.java:2: error: incompatible types: boolean cannot be converted to int on java9, 10, and 11. Not on 8.

NB: Just plain 'javac' is enough, you don't need gradle or maven to be involved. The chaining is key; if you write var x = a(x()); x.b(y()); it compiles fine.

Great! Thanks!
