build-jar-repository
BUILD-JAR-REPOSITO(1) Java Packages Tools BUILD-JAR-REPOSITO(1)
NAME
build-jar-repository - create a symbolic link to a JAR
SYNOPSIS
build-jar-repository [OPTION]... DIRECTORY JAR|artifact-coordinates
DESCRIPTION
Build a JAR repository in the named directory by copying files or creating symbolic links. The JARs can be identified by their names or
Maven artifact coordinates. Artifact coordinates specify Maven artifact and are in format
groupId:artifactId[:extension[:classifier]]:version. If extension is omitted then "jar" is used. If classifier is omitted then empty
classifier is used. For more information see XMvn Configuration Reference.
OPTIONS
If no option is specified the default action will be to create symbolic links
-c, --copy
Copy files.
-h, --hard
Create hard links.
-p, --preserve-naming Try to preserve the names of the original JAR files (in case of a nested hit the slashes in the path will still be
replaced by underscores). Using this option makes any future automated repository rebuild impossible, and implies -c unless specified
otherwise.
-s, --soft, --symbolic Create symbolic links (default).
--help Display help text
EXAMPLES
build-jar-repository . jndi - This will create a symbolic link to the jndi JAR in the current working directory.
build-jar-repository -h /tmp log4j - This will create a hard link to the log4j JAR in /tmp directory.
build-jar-repository -c . org.apache.commons:commons-io - This will copy commons-io JAR to the current working directory.
