How to create a repository id in a generated target? [message #1784075]

We define our targlet in Oomph and generate a target definition from it using TargetDefinitionGenerator.

Our build server uses this target definition. In order to access some of the repositories, we need to supply an repository id, so maven can relate this to the correct credentials.

Is there any way to store the ID in Oomph? Currently, we need to adjust the generated target definition manually.

The current generated target definition looks like

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?pde version="3.8"?>
<target name="Generated from My GIT" sequenceNumber="23">
  <locations>
    <location includeAllPlatforms="false" includeConfigurePhase="true" includeMode="planner" includeSource="false" type="InstallableUnit">
      <unit id="org.eclipse.egit.feature.group" version="4.9.2.201712150930-r"/>

      <repository  location="https://some/internal/repo/requiring/authentication/"/>

      <repository location="http://download.eclipse.org/releases/oxygen"/>
    </location>
  </locations>
</target>

We need to supply an id to the first repository location:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?pde version="3.8"?>
<target name="Generated from My GIT" sequenceNumber="23">
  <locations>
    <location includeAllPlatforms="false" includeConfigurePhase="true" includeMode="planner" includeSource="false" type="InstallableUnit">
      <unit id="org.eclipse.egit.feature.group" version="4.9.2.201712150930-r"/>

<!-- ID ADDED-->
      <repository id="myCustomId" location="https://some/internal/repo/requiring/authentication/"/>

      <repository location="http://download.eclipse.org/releases/oxygen"/>
    </location>
  </locations>
</target>

If there was no way to do this, we might develop a patch for Oomph. What do you think would be the best way to store the ID within the oomph file? I could imagine extending the internal model for repositories, or creating an annotation for repositories that's recognized by the TargetDefinitionGenerator.

Is this something the PDE editor allows you to specify? It seems to me this isn't something PDE would ever produce or allow you to specify via the forms, but you can add it by hand and it does no harm, right?

I'd definitely not extend the model for Repository in this regard, but some additional annotation for the target definition generator seems okay. I wonder if it's important to be able to specify exactly the ID, or if it would be sufficient to synthesize an ID from the location value? It would of course be simpler to have a boolean flag asking to generate IDs as opposed to annotations with the specific IDs, but of course either are possible...

It seems the id attribute is specific to Tycho. It is read into this Tycho class: https://github.com/eclipse/tycho/blob/master/tycho-bundles/org.eclipse.tycho.core.shared/src/main/java/org/eclipse/tycho/core/resolver/shared/MavenRepositoryLocation.java

Handling authorization credentials is not an easy task in itself, so I'd rather have no limitations on the id we use.

Feel free to open a Bugzilla. It shouldn't be so hard to implement, as long you're clear on the intended design. I.e., an annotation on the Repository? A annotation specifying mappings between URLs and IDs?
