I’m excited to announce I'm joining @moderneinc to work on @OpenRewrite!

What started with Open Source Contributions a year ago, and grew into conference speaking, has now ultimately brought me working there full-time.

I can't wait to see where this will go!

Upgraded to Maven 3.10.0 and an untouched pom.xml now fails? 😅 Duplicate dependency and plugin declarations used to warn. Now they stop the build. 🛑

@TimteBeek's new OpenRewrite recipe fixes them in every repo:
buff.ly/iVFhJ5t

Our next #JCON2026 session is live: 'Better #Assertions with #AssertJ' with @timtebeek

Not all #testing libraries are equal. Sure they all run your tests, but what happens when they #fail? “Expected ‘true’, was ‘false’” won’t help you …
