Dependency

Syntax

org:name:version

Bill Of Material

One can pass a Bill-Of-Material, or BOM, via dependencies, like

com.google.protobuf:protobuf-java-util,bom=com.google.protobuf%protobuf-bom%4.28.1

Note the use of % rather than : to separate the components of the BOM coordinates.

Gradle Module Variant

One can add Gradle Module attributes to a dependency, so that it checks if a Gradle Module file exists for that dependency, and uses it to pick a "variant" of that dependency:

org.jetbrains.kotlinx:kotlinx-html-js:0.11.0,variant.org.gradle.usage=kotlin-runtime,variant.org.jetbrains.kotlin.platform.type=js,variant.org.jetbrains.kotlin.js.compiler=ir,variant.org.gradle.category=library

If we split / indent that dependency for readability, we get

org.jetbrains.kotlinx:kotlinx-html-js:0.11.0,
  variant.org.gradle.usage=kotlin-runtime,
  variant.org.jetbrains.kotlin.platform.type=js,
  variant.org.jetbrains.kotlin.js.compiler=ir,
  variant.org.gradle.category=library

Gradle Module attributes are key-value pairs. These are added as parameters to dependencies. variant. is added as prefix to the key of the attribute, and the parameter value is the attribute value.
