I want to build my project using ant
but I have a small problem. My problem is that I need the output jar
have all my .class
and all my jar
dependencies extracted not zipped.
<project name="ivy example" default="compress" xmlns:ivy="antlib:org.apache.ivy.ant">
<target name="resolve" description="Resolve and retrieve with ivy">
<ivy:resolve />
<ivy:cachepath pathid="compile.path" />
</target>
<target name="compile" depends="resolve" description="compilation">
<mkdir dir="build/classes" />
<javac srcdir="src" destdir="build/classes">
<classpath refid="compile.path" />
</javac>
</target>
<target name="compress" depends="compile">
<jar destfile="output/engine.jar" filesonly="true" update="true">
<fileset dir="build/classes" />
<fileset dir="lib"/>
<manifest>
<attribute name="Created-By" value="vireton"/>
<attribute name="Main-Class" value="HelloIvy"/>
</manifest>
</jar>
<echo>Building .jar file completed successfully!</echo>
</target>
</project>
That code generates my engine.jar
with the output classes
+ dependencies.jar
.
I want it to generate my classes and the dependencies extracted.
Can anyone help?

You have your dependency jar files available as a path thanks to
<ivy:cachepath pathid="compile.path" />
so the simplest way to bundle them all into your final jar would be (assuming Ant 1.8 or later)
<jar destfile="output/engine.jar" filesonly="true" update="true">
<fileset dir="build/classes" />
<archives>
<zips>
<path refid="compile.path"/>
</zips>
</archives>
<manifest>
<attribute name="Created-By" value="vireton"/>
<attribute name="Main-Class" value="HelloIvy"/>
</manifest>
</jar>
This will read the jars directly from your ivy cache, you don't need to retrieve
them into a local lib
directory first.

i did it by extracting the dependencies to a tmp directory then make a jar of both directories (src & tmp)
<target name="compress" depends="compile">
<delete file="output/engine.jar" />
<mkdir dir="tmp" />
<unzip dest="tmp">
<fileset dir="lib">
<include name="*.jar" />
</fileset>
</unzip>
<delete dir="tmp/META-INF" />
<jar destfile="output/engine.jar" update="true">
<fileset dir="build/classes" />
<fileset dir="tmp"/>
<manifest>
<attribute name="Created-By" value="vireton"/>
<attribute name="Main-Class" value="HelloIvy"/>
</manifest>
</jar>
</target>
and i found an even better way to do it using
<target name="compress" depends="compile">
<delete file="output/engine.jar" />
<jar destfile="output/engine.jar" update="true">
<zipgroupfileset dir="lib" includes="*.jar"/>
<zipfileset dir="build/classes" />
</jar>
</target>

Extract all the jars of the lib folder to some temporary folder (using the unjar task), then create the engine.jar by adding this temporary folder as a fileset.
Just like you would do it by hand.
