The Maven Central 2022 Dataset

We present the Maven Central 2022 Dataset (MC22), based on a snapshot of Maven Central dated April<br> 4, 2022, for our replication study and future scientific work. The dataset contains metadata on jars in Maven Central and evolution metrics on syntactically SemVer-adhering<br> artifacts. It can be used to answer questions like: How often and when are updates of existing components<br> published? How do version tags look like and how do their syntactical forms change over time? How<br> common is the use of deprecation tags? and many more. The dataset contains three groups of information: Metadata on all jars in the snapshot, metrics on an-<br> alyzed upgrades and metrics on analyzed components. The metrics are calculated seperately regarding<br> three types of elements: public classes, public methods and protected methods.
