NAME
mvn_alias - add alias(es) for Maven artifact(s) SYNOPSIS
%mvn_alias artifact-coordinates alias [alias ...] DESCRIPTION
mvn_alias macro causes instructions for artifact installation to be added to XMvn reactor configuration. It is used to specify alternative names (aliases) for Maven artifacts. Specified artifact coordinates must match at least one artifact. If not then behavior is unspecified. It is possible to specify artifact coordinates matching multiple artifacts, so one call to mvn_alias can affect installation of more than one artifact. OPERANDS
artifact-coordinates Artifact coordinates specify artifact(s) that this rule applies to. Coordinates are in format groupId:artifactId[:extension[:classifier]][:version]. If extension is specified then version must be specified too. If any part is omitted or equal to empty string then it matches any string. Wildcards and brace expansions are supported in each part. For more information see XMvn Configuration Reference. alias Coordinates specifying artifact alias (alternative name under which matching artifacts will be available). Coordinates are in format groupId:artifactId[:extension[:classifier]][:version]. If extension is specified then version must be specified too. If any part is omitted or equal to empty string then corresponding part from artifact-coordinates will be substituted. Backreferences are supported in form @n, where n is an integer corresponding to brace in artifact-coordinates. AUTHOR
