A Twitter bot to explore the Awesome Java list

I love making lists. I use them to organize my day, remember important things, and keep track of tools and libraries I want to explore. Lists like Awesome Java are a treat for people like me. Curated content on a technology I like and use everyday? Sign me in!

But the truth is: I am too lazy to actually read the list and select an entry I want to explore. Like many list makers, I end up with piles of lists (and even lists of lists!) that are just collecting dust. I believe these lists are missing one key ingredient to be really useful. I don't want to look at them, I want their content to be pushed directly in front of me.

So I created a Twitter bot that does exactly that. It uses the curated content from the Awesome Java list and posts a daily tweet with a random entry, directly into your feed.

If you are interested you can follow @daily_awsm_java. The list contains more than 500 entries (kudos to @akullpp for the hard work 🙏), so there will be fresh content for quite some time 😉

You can also take a look at the original post on the Xatkit blog if you want to learn more about the technology behind the bot.

And let me know if you'd like to see more Awesome List bots on Twitter! The Awesome list of lists is full of interesting topics to explore!

Configure IntelliJ to show warnings for Lombok's @NonNull

Lombok is a library I like to use in my projects to limit boilerplate code and focus on the core logic of my applications. I am using the IntelliJ plugin to integrate Lombok annotation processing with my IDE, for example to enable auto-completion of methods generated from @Getter/@Setter.

While this works pretty well, I regularly find myself searching resources on how I can configure Intellij to show warnings when I provide a null value to a method argument annotated with @NonNull. Since a picture is worth a thousand words here is what I try to achieve:

Since I spent some time figuring this out today I'll post my solution here in case anyone is wondering how this can be done (and also as an archive I can retrieve later 😅):

Open File -> Settings
Navigate to Editor -> Inspection -> Java -> Probable bugs -> Nullability problems -> @NotNull/@Nullable problems
Click on Configure Annotations in the right panel
Add lombok.NonNull in the NotNull annotations list
Rebuild your project

You should now see the warnings in your editor

You may have noticed the naming error in the warning pop-up ("@NotNull" instead of "@NonNull"). I didn't look into it, let me know if you have a solution for that!
