Introduction into C++ Builds with Gradle

Shadow plugin: "Shadow is a Gradle plugin for combining a project's dependency classes and resources into a single output Jar. The combined Jar is often referred to a fat-jar or uber-jar. ... Shadowing a project output has 2 major use cases: (1) Creating an executable JAR distribution, and Bundling and relocating common dependencies in libraries to avoid classpath conflicts."

Notes

Gradle uses a 1:1 relationship of a build script to a Project instance. Most "magic" comes from the use of plugins (listed below). Thus, the world's simplest Gradle build:

// build.gradle.kts
println("Hello Gradle")

... when run with gradle -b build.gradle.kts:

~/Projects/Exploration.git/Gradle % gradle -b build.gradle.kts 

> Configure project :
Hello Gradle

> Task :help

Welcome to Gradle 8.10.

To run a build, run gradle <task> ...

To see a list of available tasks, run gradle tasks

To see more detail about a task, run gradle help --task <task>

To see a list of command-line options, run gradle --help

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.10/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.
