Best of Java 2026

• Flavour single-page app framework: Make a full web app without a line of JavaScript! Now faster and better than ever. See lots of short examples in the Tea Sampler, or read the Flavour Book.
• Fray: A Unique Tool for Java concurrency testing
• web-push: Add web push notifications to your Java project.
• BigBone: A Mastodon library for Java.
• mvnd — The Maven Daemon. Type one extra letter, speed up your maven builds by 20-50%! Seriously, try it and see for yourself. mvnd is a drop-in replacement for maven. Once installed, just type mvnd in place of mvn and mvnd runs your builds using an in-memory, always running daemon process. After the first build, cached classes and data ensure markedly faster builds. If your development cycle is code/maven/test/repeat, you can see a significant increase in productivity.
• Picocli: Makes command-line app coding easy, so you can worry about your logic, not parsing and help text.
• Maven Shade Plugin: Create single-jar apps with all dependencies, just by adding one plugin to your POM.
