Iterate over ... just one item

[JeromeRauline]

Hi,

I can't implement my use case with the plugin right now. My use case =>
I want to install my WebApp on multiple environnements, let say : dev, test, prod.
In test there are 2 Tomcat instances, prod 3 isntance, and just one in dev.

So I want my build to auto adjust the number of times I invoke the tomcat plugin to install my WAR file. My idea was to declare some properties in profiles.

So for 1 instance I want to set a property tomcatUrl
For 2 instances : tomcatUrl, tomcatUrl2
For n instances : tomcatUrl, tomcatUrl2, ... tomcatUrlN

I'm trying to use the plugin to iterate over a list, calculated at runtime by another Mojo that check how many properties starting with tomcatUrl are set.
Then I create a content with ,2,...N, and configure tomcat install mojo with ${tomcatUrl@item@}
It works great !

BUT, if only the first one is set, my content looks like so the plugin invoke nothing.
That's because, in AbstractIteratorMojo the getItems() methods check with isContentSet() there is a non empty value.
And in my case, I don't want to rename my first var as tomcatUrl1 ....

So i'd like

Prop 1) a new property to allow empty item ==> no trim() in isContentSet().
Prop 2) change the getItems() to not check if the content is set

protected List<String> getItems() throws MojoExecutionException {
    List<String> result = new ArrayList<String>();
    if (isItemsSet()) {
        result = items;
    } else {
        result = getContentAsList();
    } 

    return result;
}

Can you create a simple project which reproduces the problem. Best might be to create a github project or make a attachment to the issue.
