In this task you will learn how to build the AMP file using the simple Ant
script you created earlier in this tutorial.
An AMP file is simply a Zip
file that has an .amp file extension instead of a .zip
extension, and whose contents is laid out in a particular structure (as you have seen in the
previous tasks).
To create the AMP file you first need to build a Zip file containing the module contents, and with a file extension .zip. The resultant AMP file then needs to be located in the amps directory of the SkyVault installation. The relevant section of the Ant build script is:
<!-- Create AMP -->
<target name="create-amp" depends="mkdirs" description="Creates the AMP file">
<zip destfile="${dist.path}/${module.id}.amp"
basedir="./"
includes="**/*"
excludes="${dist.path}, ${dist.path}/${module.id}, ${ant.file}, build*.xml"/>
</target>
<!-- Install AMP -->
<target name="install-amp" depends="mkdirs, create-amp" description="Copy AMP file to amps directory">
<copy file="${dist.path}/${module.id}.amp"
todir="${amp.path}"/>
</target>
There are two steps here:
- Create the Zip file.
- Copy the AMP to the amps directory of the SkyVault installation.
A copy of the AMP file into the amps directory is performed, rather than a move, for convenience, as it is handy to leave a copy of the AMP file in the dist directory, in case it needs to be reinstalled.
To build the AMP file simply type ant in the project
directory. This will run the default target. The default target will invoke the
mkdirs, create-amp and
install-amp targets.
You have now built the AMP file and located it in the target directory. However, you
must now use the Module Management Tool to complete the installation of the AMP
file.
