Here is a task that does some like that:

package task;

import org.apache.tools.ant.taskdefs.Sequential;


public class NoFail extends Sequential {
    private String failureProperty;
    public void setFailureProperty(String name) {
        this.failureProperty =3D name;
    }
    public void execute() {
        try {
            super.execute();
        } catch (Throwable t) {
            if (failureProperty !=3D null) {
                getProject().setNewProperty(
                    failureProperty, "true");
            }
        }
    }
}

Usage:
<project>
  <mkdir dir=3D"classes"/>
  <javac srcdir=3D"src" destdir=3D"classes"/>
  <taskdef name=3D"nofail" classname=3D"task.NoFail"
           classpath=3D"classes"/>

  <target name=3D"test">
    <nofail failureproperty=3D"failed">
      <fail>This should fail</fail>
      <echo>This will not be reached</echo>
    </nofail>
    <echo>failed is ${failed}</echo>
  </target>
</project>
