Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Unchecked Java: Say Goodbye to Checked Exceptions Forever
This is every Lombok lover's favorite strawman argument I've run into.
I've been coding in Java professionally for ~20 years. I can count with zero hands the number of times I've been burned by a getter or setter getting changed into something surprising.
If you really need auto-generated getters/setters/builders - Immutables [1] is a library that does it using bog standard annotation processing rules that don't require hacking your build process.

[ANN] RecordBuilder v33 Released

ExpressiveJava: Re-implementing a simple Scala interpreter in JDK 8/15/17. JDK 17 code nearly identical with use of Records + Pattern Matching + Sealed Types.
That's good, but I prefer this : https://github.com/immutables/immutables It has all sorts of neat stuff like lazy, defered, cached, defaults etc. Just needs updating to use records.

Stop using noargsconstructors and setters (and builders)
Not bad :) I like using Immutables (which is backed by the style of implementation referenced in the link in https://github.com/immutables/immutables/issues/450)

If you could change one thing in the Java and one thing in the JVM, what would you change?
Annotation processors? Like Immutables? Those already exists, but the major difference is that an annotation processor cannot change the processed class, but has to create another one.

Popular technologies for a full-stack Java developer
While you’re looking into this I would highly recommend checking out immutables. https://github.com/immutables/immutables It is pretty popular in the industry and very nice!

Searching a specific annotation processing library
I like to use Magic Bean for this kind of stuff if I can't use records for some reason.

Java is your preferred language, but if you could press a button...
I recently stumbled upon https://github.com/bowbahdoe/magic-bean . This would be an example of solving developer needs - compatibly with the jdk way but currently ugly. Maybe we can make it nicer in the future somehow?

Should you still be using Lombok?
I think Hibernate / cases where real getters and setters are desired are the remaining usecase. The code generator I published however long ago handles specifically that boilerplate, but its Java 17+ only. https://github.com/bowbahdoe/magic-bean
- Any suggestions for good open source Java codebases to study(With below criteria)?
- has anyone written custom annotations using Lombok ?

[ANN] RecordBuilder v33 Released
And if you want non-magic getters and setters there is this: https://github.com/bowbahdoe/magic-bean
- Do you think Java will some day finally remove the need of Lombok's @Data annotation?
- Magic Beans - automatic get/set, equals, hashCode, toString without any compiler hacks
What are some alternatives?
Lombok - Very spicy additions to the Java programming language.
record-builder - Record builder generator for Java records
Auto - A collection of source code generators for Java.
MFL - A Java library for reading and writing MATLAB's MAT File format
AspectJ
leftright-map-java - A (hopefully) Fast, (hopefully) Thread safe map inspired by evmap
jsonschema2pojo - Generate Java types from JSON or JSON Schema and annotate those types for data-binding with Jackson, Gson, etc
manifold - Manifold is a Java compiler plugin, its features include Metaprogramming, Properties, Extension Methods, Operator Overloading, Templates, a Preprocessor, and more.
Spring Loaded - Java agent that enables class reloading in a running JVM

JHipster - JHipster, much like Spring initializr, is a generator to create a boilerplate backend application, but also with an integrated front end implementation in React, Vue or Angular. In their own words, it "Is a development platform to quickly generate, develop, & deploy modern web applications & microservice architectures."
