UnmodifiableList while trying to programmactically add a Builder to a Job

[Steve Maring]

I have hundreds of Jobs that I would like to programmatically add an initial build step to using the Build Flow Plugin

When I try something like this ...

        String jobName = "MY_JOB";

List<TopLevelItem> topLevelItems = Jenkins.getInstance().getAllItems(TopLevelItem.class);

Job job;

Iterator<TopLevelItem> topLevelItemsIterator = topLevelItems.iterator();

while (topLevelItemsIterator.hasNext()) {

TopLevelItem topLevelItem = topLevelItemsIterator.next();

Collection<? extends Job> jobs = topLevelItem.getAllJobs();

       job = (jobs.toArray())[0];

if (job.getName().equals(jobName)) {

break;

} else {

job = null;

   }

}

FreeStyleProject project = (FreeStyleProject) job;

List<Builder> builders = project.getBuilders();

Shell propertyVersionsCommand = new Shell("echo 'Hello World'");

builders.add(0, propertyVersionsCommand);

I get ...

ERROR: Failed to run DSL Script

Under "Project-based Matrix Authorization Strategy" I've confirmed that I have EVERY perm possible checked there.

What am I missing?

Use getBuildersList instead. The following works for me in the Script Console:

def i = Jenkins.instance.getItemByFullName("foo") // might be different from yours
def l = i.buildersList
def oldBuilders = l.toList()
l.clear()
l.add(new hudson.tasks.Shell("echo 'Hello World'"))
l.addAll(oldBuilders)
i.save()

Thank you Daniel.  That worked perfectly.

Now I'm trying to figure out how to add a BooleanParameterDefinition and a single step conditional builder, keying off that boolean, to execute the shell script.
