/**
* A command line tool that can be used to index local Maven repository.
*
* The following command line options are supported:
*
*
-repository : required path to repository to be indexed
*
-index : required index folder used to store created index or where previously created index is
* stored
*
-name : required repository name/id
*
-target : optional folder name where to save produced index files
*
-type : optional indexer types
*
-format : optional indexer formats
*
* When index folder contains previously created index, the tool will use it as a base line and will generate chunks for
* the incremental updates.
*
* The indexer types could be one of default, min or full. You can also specify list of comma-separated custom index
* creators. An index creator should be a regular Plexus component, see
* {@link org.apache.maven.index.creator.MinimalArtifactInfoIndexCreator} and
* {@link org.apache.maven.index.creator.JarFileContentsIndexCreator}.
