override the classpath given in the build file and cause ant to be confused.
So just use:
<antlib>
<taskdef name="renamepackages" classname="org.appfuse.ant.RenamePackages"/>
</antlib>
For example: src/testing/UseSpring.java: package testing; import org.springframework.beans.PropertyValue; import org.apache.tools.ant.Task;
public class UseSpring extends Task {
private PropertyValue pv = new PropertyValue("hello", "world");
public void execute() {
log("pv is " + pv);
}
}
src/testing/antlib.xml:
<antlib>
<taskdef name="usespring" classname="testing.UseSpring"/>
</antlib>build.xml:
<project name="testspring" default="use">
<target name="jar">
<mkdir dir="classes"/>
<javac srcdir="src" destdir="classes" classpath="lib/spring.jar"/>
<copy todir="classes">
<fileset dir="src" includes="**/*.xml"/>
</copy>
<jar destfile="usespring.jar">
<fileset dir="classes"/>
</jar>
</target><target name="use" depends="jar">
<typedef resource="testing/antlib.xml" classpath="usespring.jar:lib/spring.jar"/>
<usespring/>
</target>
</project>
Outputs: Searching for build.xml ... Buildfile: /home/preilly/learning/a/spring/build.xml
jar:
[mkdir] Created dir: /home/preilly/learning/a/spring/classes
[javac] Compiling 1 source file to /home/preilly/learning/a/spring/classes
[copy] Copying 1 file to /home/preilly/learning/a/spring/classes
[jar] Building jar: /home/preilly/learning/a/spring/usespring.jar
use: [usespring] pv is PropertyValue: name='hello'; value=[world]

Hi ,
Yes I have tried that (well a variety of this type of thing) and it is not working for me...
In my 'main' build.xml file I do this:
<typedef resource="org/appfuse/ant/appfuse-contrib.xml" classpath="spring.jar;rename-packages-1.0.jar" uri="appfuse:/org.appfuse.ant"/>
Then, in my appfuse-contrib.xml file I do:
<?xml version="1.0"?> <antlib>
<taskdef name="renamepackages" classname="org.appfuse.ant.RenamePackages" classpath="spring.jar" onerror="fail"/>
</antlib>
But whatever I try setting either classpath to (or even if I use inline classpath, or classpathref), my custom ant task cannot find the spring classes..
Is it possible what I am trying to do? Eric's article + other postings I have read seem to suggest, the only two ways of using 3rd party classes from wthin a custom task is to ether a) kick off a new JVM task or b) put the jars in the System classpath (ie. ANT_HOME/lib)..
Can anyone confirm either way??
