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.

Consuming and Testing third party API's using Spring Webclient
The above class maps the json data to a java object we can work with. We use Lombok to generate constructors, getters and setters for our code and the Jackson Project to handle serialization and deserialization of json to pojo . We know the response is an array of objects representing the coffee and so above data structure is fit for this.

💻 7 Open-Source DevTools That Save Time You Didn't Know to Exist ⌛🚀
Almost a decade ago, I started reducing my boilerplate (and saving time with Lombok. It made my life much easier, simple as that. Ever since I've been looking into finding the smoothest solutions for saving time rather than handling all of it myself.

Feedback on a new annotation processor api
I gotta agree with /u/rzwitserloot I don't see anything in the lombok repo that indicates they have their "own compiler". I see the "reaching into javac internals" but that's it.

Does any tooling exist for Java to add @NotNull to every parameter, return type, field, etc. by default?
i looked into that and found this: https://github.com/projectlombok/lombok/issues/2310

X-Pipe - A connection manager and remote file explorer. Let me know what you think!
I get the main criticisms of Java, i.e. its verbosity and the requirement for a lot of boilerplate code, and understand why some people switched to Kotlin. But by using libraries such as lombok you can get rid of most of it and suddenly the incentives for switching aren't that big anymore. And in the end it's all JVM bytecode anyways.

John Carmack on Functional Programming in C++ (2018)
While you're not wrong RE: object references, Java does have the `final` keyword that you can apply to fields, local variables, method parameters, etc. This prevents the value from being re-assigned short of going out of your way to do reflection hacks and such. You can also apply it to classes themselves and prevent them from being inherited and modified that way.
The only real 'gotcha' there is that, while it prevents whatever it is applied to from being reassigned, if the value is a mutable object of some sort (e.g., an array, mutable collection, etc), it, of course, does not prevent you from modifying the contents of the array, etc.
It's been a while since I've written modern Java, but I want to say JDK 14 also brought records, which I believe are basically the equivalent of having `final` and `public` on everything as well as overriding the equality and hashcode functions on everything by default so that comparisons are done based on the contents of the object rather than the reference.
And while I am sure many people are scared of the bytecode manipulation that it performs, Lombok [1] provides a lot of little utilities that make using immutable objects totally painless - e.g., applying `@Value` to the class generates all of the necessary boilerplate at compile time, or my favorite, `@With`, which generates methods for copying an immutable object with one of the fields changed (e.g., `val newUser = olduser.withName("Nayeon");`

Build a Simple CRUD App with Spring Boot and Vue.js
Project Lombok saves a lot of clutter and ceremony code. However, if you're using an IDE, you'll need to install a plugin for Lombok. See the project's installation docs for more information.

It is becoming difficult for me to be productive in Python
Java's verbosity can even be reduced of you are able to use lombok

Should you still be using Lombok?
I wish they had a way to call a method after an annotation-generated constructor. There is an open issue from 2016 with 161 thumbs up.

Any library you would like to recommend to others as it helps you a lot? For me, mapstruct is one of them. Hopefully I would hear some other nice libraries I never try.
error-prone is good for some extra static analysis.

How to use Java Records
A special kind of validation is enforcing that record fields are not null. (Un)fortunately, records do not have any special behavior regarding nullability. You can use tools like NullAway or Error Prone to prevent null in your code in general, or you can add checks to your records:

Why is `suspend` a language keyword, but @Composable and @Serializable are annotations
I am all in favour to more third side libraries adding functionalities, like Lombok, Manifold and error prone. As well as smaller projects like this shameless plug and what appears in this list

What does the future hold for Project Amber?
I haven't used it. I use Google's ErrorProne + Lombok to prevent NPEs in java.

Is there a tool to track CVEs for the software that we use?
While at it you could also point them to static code analyzers such as error_prone, spotbugs and pmd (use all 3 at once - they complement each other in detecting different issues).

Top 5 Java Linters
5. Error Prone
- Break backward compatibility
What are some alternatives?
Spotbugs - SpotBugs is FindBugs' successor. A tool for static analysis to look for bugs in Java code.
SonarQube - Continuous Inspection
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."
Immutables - Annotation processor to create immutable objects and builders. Feels like Guava's immutable collections but for regular value objects. JSON, Jackson, Gson, JAX-RS integrations included
PMD - An extensible multilanguage static code analyzer.
Checkstyle - Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard. By default it supports the Google Java Style Guide and Sun Code Conventions, but is highly configurable. It can be invoked with an ANT task and a command line program.
manifold - Manifold is a Java compiler plugin, its features include Metaprogramming, Properties, Extension Methods, Operator Overloading, Templates, a Preprocessor, and more.
FindBugs - The new home of the FindBugs project
Auto - A collection of source code generators for Java.
record-builder - Record builder generator for Java records
AspectJ
JavaParser - Java 1-17 Parser and Abstract Syntax Tree for Java with advanced analysis functionalities.
