This includes work such as compiling, testing and documenting software, plus sharing that software via publishing and dependency management.
This platform is agnostic to what kind of software is being developed.
It might be Java or Kotlin libraries running on the JVM, Gradle plugins, Android or iOS applications, C++ libraries, and so on.

This platform does not provide special support for a particular language or ecosystem.
