Example

Create a text file with some dependencies in it. Lets call it build.dependencies

# This is a comment
mvn:org.hamcrest:hamcrest-core:jar:1.2.1
mvn://repo.bodar.com/com.googlecode.totallylazy:totallylazy:pack|sources:1125
s3://repo.bodar.com/com.googlecode.yadic:yadic:jar:151
http://jarjar.googlecode.com/files/jarjar-1.1.jar
file:///home/dan/Project/foo.jar

ShavenMaven uses an extended form of the BuildR mvn url. (This means when you use sites like http://mvnrepository.com/ you can click on the BuildR tab and just prefix it with "mvn:")

• The first line after the comment will download hamcrest-core jar from the central repository.
• The second line will download totallylazy pack200 file (and unpack it to a jar) and sources from a custom repository repo.bodar.com.
• The third line will download 'yadic' jar from 'repo.bodar.com.s3.amazonaws.com'
• The fourth line will do a plain HTTP GET request to non mavenised jar.
• The last line will look for a local file called foo.jar

You can also specify an alternative default repo for mvn urls with -Dshavenmaven.default-repository=http://uk.maven.org/maven2/

Command line usage

To actually download the jars, run the following:

java -jar shavenmaven.jar build.dependencies lib/build

Where lib/build is a directory where you want to download the jars to.

You can also update multiple dependencies files and directories at the same time by providing 2 directories:

java -jar shavenmaven.jar build lib

This will find all ".dependencies" files in "build" and create a directory with a matching name in "lib" so:

• build
  • build.dependencies
  • runtime.dependencies
  • optional.dependencies

Would create the following structure:

• lib
  • build
  • runtime
  • optional

ANT usage

To make life easy in ANT, ShavenMaven provides a macro file. Obviously ANT is xml based but it's all just syntactic sugar over the command line interface.

Importing this macro file will allow you to install ShavenMaven with a single line:

<install version="37"/>

You can then update a directory just like in the command line version

<update dependencies="build.dependencies" directory="lib/build"/>

or to do multiple files and directories in one go

<update dependencies="build" directory="lib"/>

You can also generate a maven pom from the dependencies file with something like:

<generate.pom artifact.uri="mvn:${groupid}:${artifactid}:jar:${version}"
 dependencies="lib/runtime.dependencies" directory="${artifacts}"/>
