Quarkus 2.0.0.Final released - Vert.x 4, MicroProfile 4, Continuous Testing and much more
The Quarkus team is proud to announce the availability of the Final release of Quarkus 2.0.
This version has been a gigantic effort to bring Quarkus to a whole new level, while keeping its roots: fast boot, low memory usage and developer joy.
A big thank you to everyone involved in the community, contributors, testers… This version is a team effort and wouldn’t be as great without all of you.
Migration Guide
The good news is that upgrading to Quarkus 2.0 will be very low effort and, as usual, we have a migration guide to help you.
If you encounter any issue upgrading to this new version, please report it so that we can either fix it or add the information to the guide.
What’s new?
We already presented the novelties of this version in the Alphas/CRs announcements but here is a summary of what’s new in this version.
You can also have a look at this week’s Quarkus Insights Quarkus 2.0 Launch Party, with several Quarkus contributors talking about the new features.
JDK 11 as minimal version
JDK 11 is the minimal version to use Quarkus 2.0.
JDK 8 is not supported anymore (but you can keep using 1.13.x if you are stuck with it!).
Vert.x 4
Vert.x is at the core of Quarkus.
Quarkus 2.0 brings Vert.x 4. You can learn more about it in the announcement and the What’s new blog post.
Eclipse MicroProfile 4
MicroProfile 4 is the latest evolution of the MicroProfile specifications.
All the SmallRye components in Quarkus have been updated to the latest and greatest and, apart from implementing MicroProfile 4, they also come with additional new features.
持续测试
I’ll let the stage to Stuart Douglas for that one as he’s the author of this amazing new feature.
This release contains a brand new feature improving developer productivity: Continuous Testing.
This allows tests to be run automatically in development mode,
and can be enabled by pressing r in the console (or through the Dev UI). If you enable testing, your test suite will be run
once at the start, and then continuous testing will run your tests as you are coding,
and tell you if your changes will break any tests. This will give you instant feedback on your changes, without having to
switch to a browser. As much as possible we only run tests that are relevant to the code that has been changed.
This feature has also introduced some changes that may affect your application:
-
The Class Loading model for testing is now the same as development mode (as tests need to be hot reloaded), if this causes issues for your application you can set
quarkus.test.flat-class-path=trueto revert to the old model, but it will disable continuous testing. -
If a compatible terminal is detected Quarkus will display status messages at the bottom of the console window, and react to input without the need to press enter. If this interferes with your application it can be disabled via
quarkus.test.basic-console=true(note that gradle will always use the basic console at this time). -
If you don’t want any test output in the console and just want to interact through the Dev UI you can set
quarkus.test.console=false.
Continuous Testing is part of a long tradition of developer-targeted innovation in Quarkus. As such, we are eager to hear about your feedback on it and how we can make it even better.
Here is a video presenting Continuous Testing in motion:
Quarkus CLI
Historically, you interacted with your Quarkus projects using Maven or Gradle commands. This will soon be over as Quarkus 2.0 introduces a brand new and improved Quarkus CLI.
We are still working on publishing it everywhere for easy consumption on all systems but you can already use JBang to run it.
More details in the dedicated CLI guide.
