And a sample:

<project>
    <javac srcdir="." destdir="." includeantruntime="true"/>
    <taskdef name="my" classname="MyTask" classpath="."/>
    <my normal="normal" with-dash="with-dash" unknown="unknown"
unknown2="two"/>
</project>

import org.apache.tools.ant.Task;
import org.apache.tools.ant.DynamicAttribute;
import java.util.*;

public class MyTask extends Task implements DynamicAttribute {
    String normal;
    String withDash;
    Map<String,String> otherData = new HashMap<String,String>();
    
    public void setNormal(String s) {
        this.normal = s;
    }
    
    public void setDynamicAttribute(String name, String value) {
        if (name.equals("with-dash")) {
            this.withDash = value;
        } else {
            otherData.put(name, value);
        }
    }

    public void execute() {
        log("normal   : " + normal);
        log("with-dash: " + withDash);
        if (!otherData.isEmpty()) {
            for(String key : otherData.keySet()) {
                log("- " + key + "=" + otherData.get(key));
            }
        }
    }
}
