Build Tools
A One-JAR Archive can be built using only the Java jar tool, if you spend the necessary
effort to create a directory tree that follows the required structure. But it is simpler
and easier to use one of the build-tools that know how to build a One-JAR archive. There are
currently two alternatives.
Ant: The <one-jar> taskdef
The <one-jar> Ant task supports building a One-JAR Archive, creating a main/main.jar
from a <main> section, and adding in libraries from a <lib> section.
See the following sections in this documentation for details.
Maven
There is a one-jar Maven2 SNAPSHOT plugin available at the following repository:
<pluginRepository>
<id>onejar-maven-plugin.googlecode.com</id>
<url>http://onejar-maven-plugin.googlecode.com/svn/mavenrepo-snapshot</url>
</pluginRepository>
There is a one-jar Maven2 release plugin available at the following repository:
<pluginRepository>
<id>onejar-maven-plugin.googlecode.com</id>
<url>http://onejar-maven-plugin.googlecode.com/svn/mavenrepo</url>
</pluginRepository>
The plugin embeds the one-jar-boot-0.97.jar file as a resource. To determine which version of One-JAR
the plugin is using, examine the contents of the ".version" file in the embedded one-jar-boot
file. Or alternatvely, build a One-JAR archive and run it with the --one-jar-version argument.
