Quarkus: Lombok @Builder not producing builder class in submodule of multi-module Gradle project

[mklueh]

Describe the bug

Lombok won´t produce the builder class with the @Builder annotation in the library module, but it works as expected in the application module

Caused by: java.lang.ClassNotFoundException: com.demo.common.model.SharedModel$SharedModelBuilder at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:583) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521) ... 22 more

To Reproduce

I´ve made a demo project to reproduce this issue

[Postremus]

I can reproduce this, or at least the root cause, without much trouble in a maven multi module project.

The problem is, I think at least, that the maven-compiler-plugin is only triggered for the module, where the quarkus-maven-plugin is included.
No compilation is done for librarys. The compiler-plugin is not triggered for them.

@Postremus This sounds like another issue I´ve posted, where the library module is not compiled into the classpath at all https://github.com/quarkusio/quarkus/issues/7365 . In case of the @Builder issue the class with the annotation is compiled, but not Builder class is generated

Appears to be fixed in 1.3.0.Final. Thanks for the report!
