Self-contained applications include everything that an application needs to run. If your application requires an external library, that library can be added to the bundle for the application. Adding the library can be done in different ways.
The File Association Demo described in
Using File Associations downloads the Groovy library as part of the build process. The library is placed in the /lib directory in the project for the application. This directory is then copied to the /dist directory from which the self-contained application bundle is generated.
The following code in the -pre-init task in the build.xml file shows how the library is downloaded:
<!-- download and copy groovy library -->
<copy toFile="lib/groovy-all-2.3.8.jar">
<resources>
<url url="http://central.maven.org/maven2/org/codehaus/groovy/groovy-all/2.3.8/groovy-all-2.3.8.jar"/>
</resources>
</copy>
See
build.xml for the complete build code.
