PicoInitializationException when trying to run custom plugin

Hi,

I'm getting PicoInitializationException when trying to run custom  
plugin with Ant (version 1.6.5) running on Eclipse.
I have tested Beaninfo plugin and it is working fine, but my own  
plugin based on Beaninfo is not working.

Here is my Plugin code (it is simply cut and pasted from Beaninfo):
----
package org.xdoclet.plugin.object2hashmap;

import java.util.HashMap;

import org.generama.QDoxCapableMetadataProvider;
import org.generama.TemplateEngine;
import org.generama.VelocityTemplateEngine;
import org.generama.WriterMapper;
import org.generama.defaults.JavaGeneratingPlugin;

import com.thoughtworks.qdox.model.JavaMethod;
import com.thoughtworks.qdox.model.JavaParameter;
import com.thoughtworks.qdox.model.Type;

public class Object2HashtablePlugin extends JavaGeneratingPlugin {

protected Object2HashtablePlugin(VelocityTemplateEngine templateEngine,
QDoxCapableMetadataProvider metadataProvider,
WriterMapper writerMapper) {
super(templateEngine, metadataProvider, writerMapper);

setMultioutput(true);

setFileregex("\\.java");
setFilereplace("BeanInfo.java");

}

public boolean shouldGenerate(Object metadata) {
return true;
}

public String getParameterTypes(JavaMethod method) {
StringBuffer result = new StringBuffer();
JavaParameter[] params = method.getParameters();
for (int i = 0; i < params.length; i++) {
if (i > 0) {
result.append(", ");
}
result.append(typeToClass(params[i].getType()));
}
return result.toString();
}

private String typeToClass(Type type) {
String result = type.getValue();
if (primitiveMap.get(result) != null) {
return (String) primitiveMap.get(result);
}

return result + ".class";
}

private static final HashMap primitiveMap = new HashMap();
static {
primitiveMap.put("boolean", "Boolean.TYPE");
primitiveMap.put("int", "Integer.TYPE");
primitiveMap.put("long", "Long.TYPE");
primitiveMap.put("short", "Short.TYPE");
primitiveMap.put("float", "Float.TYPE");
primitiveMap.put("double", "Double.TYPE");
primitiveMap.put("byte", "Byte.TYPE");
}

}

And here is my ant build.xml ----
<project default="init" basedir="../">

<property name="build_config" location="config" />
<property file="${build_config}/build.properties" />

<path id="generator.compile.classpath">
<fileset dir="${xdoclet.home}">

</fileset>
</path>

<target name="xdoclet-taskdef" depends="package-generator">

</xdoclet>
</target>

</fileset>
</copy>
</target>

<target name="package-generator" depends="compile-generator">
<jar jarfile="${generator-bin}/generator.jar"  
basedir="${generator-bin}/classes" manifest="${generator.manifest}"
/>
</target>

</project>
----

I get this error (with no message):
----
BUILD FAILED
C:\Documents and Settings\lsoksane\My  
Documents\workspace\xdoclet-workspace\config\build.xml:60:  
org.picocontainer.PicoInitializationException
----
where line number refers to the line:
----
<xdoclet verbose="true">
----

Any suggestions what should I do?
