The uninstal.jar file is inside standalone-compiler.jar , so this is not the
problem.
My ant file is like this
<?xml version="1.0" encoding="UTF-8"?>
<project name="Installer Generator" default="default" basedir=".">
<taskdef name="izpack"
classpath="/Users/jacobo/Documents/workspace/Eclipse Installer
Generator/izpack/lib/standalone-compiler.jar" classname="
com.izforge.izpack.ant.IzPackTask" />
<target name="default" description="Main target">
<izpack input="/Users/jacobo/Desktop/export/tmp/installer.xml"
output="/Users/jacobo/Desktop/jacobo-installer.jar"
basedir="/Users/jacobo/Desktop/export/tmp"
izpackdir="/Users/jacobo/Documents/workspace/Eclipse Installer Generator/"
/>
</target>
</project>
Here is the folder structure of the plugin, Eclipse Installer Generator is
root plugin folder
Eclipse Installer Generator/izpack/lib/installer-generator.jar
I've been trying changing last part izpackdir attribute to every combination
of (izpack, izpack/lib, izpack/lib/installer-generator.jar)
Nothing of this worked.
Thanks again for your time.
