I found my problem. As expected, it was a simple one. The constructor
for PreBuildCleanup requires two arguments; the list of patterns and a
boolean determining whether or not to apply the patterns to directories.
Somehow I must have been looking at an old version of the javadoc for
hudson.plugins.ws_cleanup, before the directories option was added.
Here's the working script, which I ran from the Groovy console in
Jenkins 1.466.2.

======================================
import hudson.tasks.*
import hudson.plugins.ws_cleanup.*
List<Pattern> lp = new ArrayList<Pattern>();
for(item in Hudson.instance.items) {
if (item.name == "my_example_jenkins_job") {
hasPreClean = false;
item.buildWrappers.values().each{
if (it instanceof hudson.plugins.ws_cleanup.PreBuildCleanup){
hasPreClean = true;
}
}
if (!hasPreClean) {
println("Adding PreClean to $item.name");
item.getBuildWrappersList().add(new PreBuildCleanup(lp, false) );
item.save();
}
else {
println("$item.name already has pre-build cleanup enabled");
}
}
}
=========================================

I've been working on a Groovy script to add PreBuildCleanup to certain
jobs. I followed the example of the Groovy script to add timestamper
to all jobs [1]. The problem is, I can't come up with the right
constructor for the PreBuildCleanup. I know it must be simple, but I'm
just learning to poke around in the Jenkins classes. Here's what I
try, running from the Script Console.
Thanks,

import hudson.model.*
import hudson.maven.*
import hudson.tasks.*
for(item in Hudson.instance.items) {
if (item.name == "my_example_jenkins_job") {
hasPreClean = false;
item.buildWrappers.values().each{
if (it instanceof hudson.plugins.ws_cleanup.PreBuildCleanup){

if(!hasPreClean)
{
println(">>>>>>>> Adding PreClean to $item.name")
item.getBuildWrappersList().add(new
hudson.plugins.ws_cleanup.PreBuildCleanup() );
item.save()
}
}
}
And the output:
