get global parameter from other plugin

[Shurik]

Hi,

I have my plugin (A) that need to get global parameter that define by other plugin (B).

I need that "A" descriptor will be able to get parameter of "B" descriptor ( via getter method )

How I can do it ?

Thanks,

Shurik

What do you mean by parameter, and in what context do you want it?

In plugin "B" in global.jelly defined 

<f:entry title="local url" field="localUrl" >

      <f:textbox />

</f:entry>

My plugin is build step and I need ability in my plugin "A" somehow to get the value of localUrl parameter.

I need it in DescriptorImpl inner class.

I suspect what Robert is (also) asking was more actually a use case than /just/ a technical description on what you currently want to do.

At least, I guess we'll need to know more precisely what you're trying to achieve from a high level PoV to be able to help you correctly.

Possibly, you want to have a look at https://wiki.jenkins-ci.org/display/JENKINS/Dependencies+among+plugins as a starting point.

Possibly, also, the right solution and the more common/standard might be to actually define an extension point in B so that A can register something against it. But again, it will depend on your use case.

Cheers

I will try to explain:

I have the below build step code.

public class MyPluginBuilder extends Builder {

private final List<MyFlow> myFlows;

...............

@Override

public boolean perform(AbstractBuild<?, ?> build, Launcher launcher, BuildListener listener)

{

for (MyFlow currentFlow : this.myFlows) {

}

return true;

}

@Override

public DescriptorImpl getDescriptor() {

return (DescriptorImpl) super.getDescriptor();

}

@Extension

public static final class DescriptorImpl extends BuildStepDescriptor<Builder> {

private String localUrls;

public String getDisplayName() {

return "My Flows";

}

public ListBoxModel getLocalUrlsList(String value) {

ListBoxModel listModel = new ListBoxModel();

for (String currentUrl : localUrls.split("\n")) {

listModel.add(new Option(currentUrl, currentUrl, currentUrl.equals(value)));

}

return listModel;

}

}

}

And I have MyFlow class definition as below

public abstract class MyFlow extends AbstractDescribableImpl<MyFlow>

{

public abstract static class MyFlowDescriptor extends Descriptor<MyFlow>

{

public MyFlowDescriptor() 

{

load();

}

}

}

In MyFlow config.jelly I need to have dropdown list with the values from getLocalUrlsList method of MyPluginBuilder class.

<j:jelly xmlns:j="jelly:core" xmlns:st="jelly:stapler" xmlns:f="/lib/form">

<f:entry field="url" title="Urls">

     <f:select />

   </f:entry>

</j:jelly> 

So, I try to find the way how I can fill the dropdown list based on getLocalUrlsList.

Try @RelativePath

Hi Robert,

Thank you for your answer.

Can I find  example how to do it? Do you know if some plugin use this option?

Thanks,
