Learn Groovy

Stay away from Groovy. It’s a horrible language. It’s quick to write but slow and difficult to read. It’s conventions make it a very error prone.

Link to the things you mention e.g. you say to get familiar with Loom. When searching for that all I get is some screen recording software (probably not what you meant).

Scala pays better than Java or Kotlin

According to what research?

They address that bad wording on subscription in the comments in that blog. If you have a fallback license to v. 2024.1 or newer the feature will stay active even if you stop your subscription.

Some comments

• If you’re just starting to develop something you don’t need multiple versions of JDK. Just use the latest LTS version (v. 21 currently).
• Git is always good to have. IntelliJ IDEA has a built in git client so others aren’t strictly needed at first
• Ultimate version of IDEA (paid software) has full support for Spring (inc. Spring initializer)
• If you run Linux podman is a good choice instead of Docker
• For plugins I’d add sonarlint (helps with code quality)
• I’d also add Spotless to the project for automatic formatting

Basically anything above assembly is a high level language. The article is not about making everything from scratch. It’s about thinking about what you’re doing and not just being lazy.

Very true.
