Questions tagged [maven-indexer]

Apache Maven Indexer (former Sonatype Nexus Indexer) is the de facto standard for producing indexes of Maven repositories. The indexes are produced and consumed by all major tools in the ecosystem.

The Maven Indexer is a library created by Sonatype Inc. and contributed to the Apache Maven team. It can produce a Lucene Index and carry out queries against it. This packed index can be downloaded from the repository and be used by:

  • Artifact repository managers
    • Check if a remote host contains an artifact, class, etc
    • Check what versions of an artifact exist
    • Resolve dependencies
  • IDE-s
    • To find out which packages contain the class you would like to import
  • Custom tools
