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.

Apache Maven JaCoCo Configuration
The tool to measure code coverage in Java is JaCoCo, but that is not the only one. There are existing things like OpenClover or in Kotlin things like Kover and so on (just to mention some).
-
Kover is a Gradle plugin for Kotlin code coverage tools (by Jetbrains IntelliJ). Does anyone try it? Is it ready for production in Android development?
Kover is still lacking basic Android support and in our Android projects we were not able to replace Jacoco yet (due to errors): https://github.com/Kotlin/kotlinx-kover/issues/18
-
Did anyone find a way to exclude compose previews from Jacoco code coverage?
Kover 0.6.1 now supports this: https://github.com/Kotlin/kotlinx-kover/issues/121

Ask HN: What is a modern Java environment?
- Language: Java 17 or Kotlin
- API Layer: For tiny projects, Vert.x API directly, for larger projects Quarkus
- DB: Postgres, in-memory H2 for simple stuff
- Testing: JUnit 5, Testcontainers to automatically start + stop DB Docker containers with tests, Mockito or Mockk (Kotlin) for mocks
- Dependency Injection: CDI (built into Quarkus, for Vert.x you can initalize Weld when the app starts)
- Build tool: Gradle with Kotlin DSL
- Other tools:
Kover: automatic code-coverage reports from JaCoCo/IntelliJ (https://github.com/Kotlin/kotlinx-kover)

Spark – A web micro framework for Java and Kotlin
https://vertx.io/
It's actively maintained with full time developers, performant, supports Kotlin out of the box, and has more features?
-
Reactive database access on the JVM
Hibernate Reactive integrates with Vert.x, but an extension allows to bridge to Project Reactor if wanted
-
Looking for a coroutine-based message broker implementation for inter-app communication.
Have you looked at Vert.x?
-
What's the state of server-side frameworks with Kotlin support today for small teams?
Explicitly so:
-
Anything close beam/otp for other languages?
I really like Eclipse Vert.x... As both an Erlang dev and Java dev, it's a great synergy and soon to have support for Virtual Threads similar to BEAM.
-
Go doesn’t do any magical stuff and I love that
There are many lean, popular, non-magical libraries in Java land. (https://quarkus.io/, https://vertx.io/, etc). Spring is a monster 😱. Its like comparing Kubernetes (written in Go) with some lean framework in another lang.

Quarkus fundamentals
In fact, it builds on top of proven standards such as Eclipse MicroProfile or frameworks such as Vert.x or JAX‑RS.
