During yesterday’s @bejug.bsky.social event, I got the idea to create an @intellijidea.com extension that reminds everyone to use mvn verify instead of clean install. Inspired by @andresalmiray.com and @tomcools.be . Here’s a sneak peek:

There is another use case for mvn dependency:analyze It can show you the dependencies you use in your code but have not declared in your pom.xml. This works because you have a transitive dependency on your classpath. Either don't use the dependency or declare it.

Using Spring Boot with Testcontainers? We've improved support so that your test setup is more lean. `@AutoConfigureTestDatabase` now detects containers and will automatically use that! If you need to revert to the old behavior, set `replace=Replace.AUTO_CONFIGURED)` on the annotation.

All this, plus: having made the switch some time ago, scripts are so much better to read when coming back after a while. Bonus points for more convenient writing on dead-keys keyboard layouts imho

🗣️ "Why would you want to use long-lived refresh tokens that generate short-lived access tokens as commonly seen in OAuth 2.0, versus long-lived access tokens? Aren’t you simply replacing one long-lived token with another?" Enjoyed reading this post by @april.social. 👉 grayduck.mn/2023/04/17/r...
A flow chart showing the interaction between a client, an authorization server, and several APIs. Using the refresh token, the client retrieves short-lived access tokens for the APIs. One of the APIs is shown as compromised, but impact is limited as the access token presented to it will expire quickly.

If you are not sure what is happening in your Apache Maven build, then run the following command to find out: mvn buildplan:list-phase You will get a nice list of plugins/goals and in which phase they are running.

Extra bonus points for using a canonical file layout for the rendered YAML files and using a single resource per file. Its then even easier to review/compare the history of a single resource in particular environment in git via the GitHub website
