Hi, all.
Will the new 1.5 zipfileset let me specify a src as a collection of
jars, rather than needing one zipfileset per jar file?
I am planning our migration to ant 1.5 beta. One of the motivators is
better jar bundling. (Here, I mean taking half a dozen jar files and
copying their contents into the output jar.)
We currently have constructs like:
<target name="bundle" depends="bundle-zip1, bundle-zip2,
bundle-zip3" />
<target name="bundle-zip1" depends="init" if="jar.extra.zip1"
description="unzip any zips to be bundled in the result">
<unjar src="${jar.extra.zip1}" dest="${compile.classes}"/>
</target>
<target name="bundle-zip2" depends="init" if="jar.extra.zip2"
description="unzip any zips to be bundled in the result">
<unjar src="${jar.extra.zip2}" dest="${compile.classes}"/>
</target>
<target name="bundle-zip3" depends="init" if="jar.extra.zip3"
description="unzip any zips to be bundled in the result">
<unjar src="${jar.extra.zip3}" dest="${compile.classes}"/>
</target>
<target name="jar-manifest" depends="bundle">
<mkdir dir="${jar.dist}"/>
<jar
jarfile="${jar.dist}/${jar.baseName}-${DSTAMP}.jar"
basedir="${compile.classes}"
compress="${jar.compress}" >
</jar>
</target>
and a project might have
bundle-zip1="../foodir/foo.jar"
bundle-zip2="../bardir/bar.jar"
So, we might have up to 25 "bundle-zip##" variables and targets, and it
is a tad confusing and hard to maintain.
As I understand it, I will soon be able to change the above to:
<target name="jar-manifest" depends="bundle">
<mkdir dir="${jar.dist}"/>
<jar
jarfile="${jar.dist}/${jar.baseName}-${DSTAMP}.jar"
basedir="${compile.classes}"
compress="${jar.compress}" >
<zipfileset src="${bundle-zip1}">
<zipfileset src="${bundle-zip2}">
<zipfileset src="${bundle-zip3}">
</jar>
</target>
and will get exactly the same results. This still requires an explicit
list of bundle-zip properties. I am pretty happy about getting rid of
the extra targets, but it would be nice to get rid of a bunch of
properties as well.
Is there any planned syntax for a zipfileset like:
<zipfileset src="${bundle-zip}">
where
bundle-zip="../foodir/foo.jar:../bardir/bar.jar"
I am not that concerned with syntax, more that I will be able to specify
a list of jars whose contents are to be extracted as a single property,
much like a classpath.
Includes and excludes will not work for this, as they related to files
_inside_ the zip/jar files.
