Hi all, I've just spent a hugely frustrating 2 hours or so trying to get a simple nested element to work within a task.
-addElementName(ObjectType t) fails (task doesn't support nested element) -addConfiguredElementName(ObjectType t) fails -createElementName works Here's pretty much the exact code from the ant manual import org.apache.tools.ant.Task; import org.apache.tools.ant.BuildException; import java.util.Vector; import java.util.Enumeration; /* from http://ant.apache.org/manual/develop.html#nested-elements * & http://ant.apache.org/manual/tutorial-writing-tasks.html */ public class EchoTest extends Task { private Vector messages = new Vector(); public void execute() throws BuildException { for(Enumeration e = messages.elements(); e.hasMoreElements();) { getProject().log("MSG: "+((Message)e.nextElement()).getMessage()); } } // works // public Message createMessage() { // Message m = new Message(); // messages.add(m); // return m; // } //doesn't public void addMessage(Message m) { messages.add(m); } public class Message { private String message; public Message() {} public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } } } and my build.xml: <?xml version="1.0"?> <project name="test-dpkg" basedir="."> <target name="init"> <taskdef name="my-echo" classname="org.apache.tools.ant.taskdefs.optional.dpkg.EchoTest" /> </target> <target name="test" depends="init"> <my-echo> <message message="1"/> <message message="2"/> </my-echo> </target> </project> output: [EMAIL PROTECTED]:~/IdeaProjects/ant-core-trunk$ ant -debug -f test-control-file.xml test Apache Ant version 1.7.1alpha compiled on May 9 2007 Buildfile: test-control-file.xml Adding reference: ant.PropertyHelper Detected Java version: 1.6 in: /usr/lib/jvm/java-6-sun-1.6.0.00/jre Detected OS: Linux Adding reference: ant.ComponentHelper Setting ro project property: ant.file -> /home/kev/IdeaProjects/ant-core-trunk/test-control-file.xml Adding reference: ant.projectHelper Adding reference: ant.parsing.context Adding reference: ant.targets parsing buildfile /home/kev/IdeaProjects/ant-core-trunk/test-control-file.xml with URI = file:/home/kev/IdeaProjects/ant-core-trunk/test-control-file.xml Setting ro project property: ant.project.name -> test-dpkg Adding reference: test-dpkg Setting ro project property: ant.file.test-dpkg -> /home/kev/IdeaProjects/ant-core-trunk/test-control-file.xml Project base dir set to: /home/kev/IdeaProjects/ant-core-trunk +Target: +Target: init +Target: test Attempting to create object of type org.apache.tools.ant.helper.DefaultExecutor Adding reference: ant.executor Build sequence for target(s) `test' is [init, test] Complete build sequence is [init, test, ] init: [antlib:org.apache.tools.ant] Could not load definitions from resource org/apache/tools/ant/antlib.xml.

Can anyone see what I'm doing wrong here, or indeed reproduce what I'm seeing (and really not being able to believe right now). I know I'm dumb, but this shouldn't be that hard :( Kev --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
