Closest

Represents the selection strategy where the closest version of a dependency is chosen. The closest version (exact or the first lower) to the current IntelliJ Platform version is selected.

This version resolving is expensive as Gradle requests all Maven repositories added to the project to resolve all available dependency versions by obtaining its maven-metadata.xml file, like: https://www.jetbrains.com/intellij-repository/releases/com/jetbrains/intellij/platform/test-framework/maven-metadata.xml
