I'm definitely not used to reading such array declarations 🙈

@lobaorn.bsky.social and @sormuras.bsky.social helped me figure out that an argument file could bypass the Windows limitation.

Both Maven and the IDE seem happy so far 🙂
Maven POM properties: <properties> <argLine>@${project.basedir}/argFile</argLine> </properties> Text file content with --add-modules, --add-opens, and --add-exports command line options needed for in-module testing

#JPMS In-module testing and Windows.

What could possibly go wrong?
An extremely long command line to execute in-module testing for AssertJ "This is fine meme" with a command line error on top: The command line is too long. [DEBUG] Closing the fork 1 after not saying Good Bye.

On GitHub:
• Create a repository named `<user>.github.io`
• Create a .well-known/atproto-did file with the DID string
• Create a _config.yml file with `include: [".well-known"]`

Go back to Bluesky, hit Verify Text File, and enjoy your new handle!

On Bluesky:
• Go to Settings -> Change Handle
• Select "I have my own domain"
• Type `<user>.github.io` as domain value
• Select "No DNS Panel" and copy the DID string

It's already been five years since I joined AssertJ 🤯

I'm truly grateful for the amazing opportunity that Joel Costigliola has given me, it made me realize how much I enjoy coding in my spare time 😄

And now I'm so excited that I'll be helping shape the next AssertJ major version! 🚀
Screenshot of the email subject I received from Joel Costigliola on 23/07/2019: "Would you like to become an AssertJ commiter?"

🍃 The Spring Framework embraces AssertJ custom assertions for MockMvc!

While only a few developers maintain AssertJ in their spare time (one here 🙋), seeing adoptions by industry-leading frameworks is incredibly motivating and further validates our efforts.

Many thanks for your trust, Spring Team!
AssertJ support for MockMvc We love AssertJ! While Spring Boot has already jumped on that train a while ago and provides several testing facilities using it, the framework team has been more conservative. At the same time, we recognize that our Hamcrest support may not fit everyone’s needs: the use of static imports make the API less discoverable and writing custom assertions is harder. Spring Framework 6.2.0-M1 provides an exhaustive support for testing your web application with MockMvc and AssertJ.

The second thing was the weird config property... I can guess what the first value is, but what about the others?

A Maven plugin could nicely wrap all of these, providing the related description.

I've been looking at how to configure code coverage on Qodana for a Maven project, using the IntelliJ coverage agent.

Compared to the equivalent JaCoCo or Gradle-based solutions, the IntelliJ agent could shine better with a Maven plugin🦉⚙️

Bashing your head against the wall because of `Stream::mapMulti` added in Java 16?

Here's a short and powerful example from @nipafx.bsky.social 👇

nipafx.dev/java-16-stre...
A Java code snippet that shows how `Stream::mapMulti` can work together with `Optional::ifPresent`. --- Stream.of(Optional.of("0"), Optional.of("1"), Optional.empty()) .mapMulti(Optional::ifPresent) // !!! .forEach(System.out::print); }

📢 Spring Batch Notion 0.1.0-M2 is out!

✨ The highlight of this release is the initial support for filtering via a fluent API that mimics the database filter option in Notion's UI.
