Gradle VS Apache Ant

A ("shared") build service is kind of like a singleton, in that when you register one in any project, it's available in all projects as a single instance. (This unfortunately turns out not to be true, in some cases, when using composite builds, but can be worked around.) An actual singleton (global static instance) doesn't work at all, for the record—try it if you want to lose some sanity. Anyway, use a build service whenever you need global mutable state in your build.

When using build tools like Maven or Gradle, you can configure environment variables in the build scripts or configuration files.

For large projects, purpose-made build tools such as Gradle and Maven are preferred for managing the directory structure since they introduce additional semantics for managing test code and other programming languages (among lots of other things). Most IDEs can integrate with these build tools easily. If you're just starting out though, I wouldn't worry too much about these, you can visit them later.

Project Build and Management: Apache Maven 3 (3.9.5), Gradle 8 (8.3)

Ktor, a powerful web framework built with Kotlin, offers a lightweight and flexible solution for building web applications. In this article, we will guide you through the process of creating a Ktor project manually using Gradle and SDKMAN!. By following the steps below, you'll have a basic Ktor project up and running in no time.

The details regarding the code compiling would vary from one project to another. For that project, it seems that it uses Gradle (a helper tool) for compiling. Check Gradle's documentation for more information.

At the moment, Java 20 is the latest version, but Java 17 is the latest LTS release. It's usually best to use an LTS release, because the latest releases won't be widely supported. And that's true of Gradle too. You're using Gradle 8.0, but not even the latest version of Gradle (8.2) fully supports Java 20. You'll have to wait for Gradle 8.3 to use Java 20.

I will not suggest truly old-school Java programming. When I started in Java, we built Java classes with the javac command. This led to writing shell scripts to build complex projects and finally, Makefiles using the Unix and Windows commands make and nmake respectively. I remember being thrilled when the Ant utility came out and we had a pure Java build tool.

Didn't know that people still use Ant for building their source code.

A build system is a program that orchestrates the execution of underlying tools such as compilers, code generators, test runners, linters and so on. Examples of build systems include the venerable Make, the JVM-centric Ant, Maven and Gradle, and newer systems such as Pants and Bazel (full disclosure: I am one of the maintainers of Pants).

You are missing a dependency: antlr. You have ant instead, which is something completely different.

make has many detractors, but I've shipped some fairly large projects using nothing but it as the build system. Once you've settled on a particular implementation of make, you can get a lot done with it. The pain comes in when you want to do even modestly interesting things and you need it to work on both GNU make and SysV (or BSD) make. Its syntax also speaks loudly as to the era which it's from, but the same could be (unfavorably) said of things like Visual Studio project files and Ant.
