How to implement doIndex() method from Jenkins RootAction class

[Cheng Bao]

I create my own implementation of RootAction in Jenkins, instead of default behavior that just render and display index.jelly, I want to do some operations. as states from http://stapler.kohsuke.org/reference.html

Index Action Method This is a slight variation of above. If there's no remaining URL and there's an action method called "doIndex", this method will be invoked. Formally, evaluate(node,[]) := node.doIndex(...)

my code is

@Extension

public class MyRootAction implements RootAction {

   public void doIndex(StaplerRequest req, StaplerResponse rsp) {

        // doing my work when user type /MyRootAction in browser bar

        // this method never executed

   }

   public void doOtherWork(StaplerRequest req, StaplerResponse rsp) {

        // doing my work when user type /MyRootAction/otherWork in browser bar

        // this method works as intended

   }

   //...

}

Any one can help me to point what I did wrong?

That looks to be correct, unless you have added a view called index.jelly or index.groovy because I think those are evaluated before doIndex.

Well taking the stapler response as a parameter is generally considered old-style, better is to return a HttpResponse

Other than that, it should work... What candidate views does it name on the 404 debug output?

It's not in the code you're showing us. I just created a new plugin that consists of just the following (+ imports in the code, and non-code boilerplate from the archetype)…

------

@Extension
public class MyRootAction implements RootAction {

@Override
public String getIconFileName() {
return "document.png";
}

@Override
public String getDisplayName() {
return "My Root Action";
}

@Override
public String getUrlName() {
return "myroot";
}

public void doIndex(StaplerRequest req, StaplerResponse rsp) throws IOException {
rsp.sendError(500, "This message shown by doIndex");
}
}
------

And when clicking the side panel link, the expected happens:

------
HTTP ERROR 500

Problem accessing /jenkins/myroot/. Reason:

This message shown by doIndex
Powered by Jetty://
------

Are you sure it doesn't execute your method?
