Re: Checking whether a step from a plugin is in actual use in an instance

[Tim Van Holder]

Daniel offered a similar suggestion off-list. I'll have a look once I get a
release out with what I have now.

One question though - what would the migration path be like?
Can a plugin include code that will update a freestyle project that uses
the DotNetFoo builder to use the DotNet builder with a Foo argument instead?
I would assume I'd normally have read-only access to the freestyle jobs.

I suppose I could just keep both around, with isApplicable() for the old
ones returning false (so that existing uses remain valid, but only the new
builder could be used for new steps), but an automatic upgrade would be
nice too.

I'd have to keep them around for pipeline use anyway; is there anything in
Jenkins that will report warnings for use of deprecated steps in a pipeline
job? There's no isApplicable() there to keep them from being written in
scripts, so if I can at least have the build report that the new steps
should be used instead, that's something. I wouldn't want to keep the old
builders around in perpetuity (even if they can become simple wrappers
around the new one).

It is possible with an `@Initializer`.

Correct.

is there anything in Jenkins that will report warnings for use of

No, but you could print a message to a `TaskListener` in case the user is
paying attention. If you want to be more aggressive, there is always
`AdministrativeMonitor`.

Potentially doable via readResolve as well.

Unfortunately you cannot do this sort of thing via `readResolve` so far as
I know.

Ideally there would be some API which you could call from `readResolve` or
otherwise mark a class which, if loaded in the context of some top-level
model object (in this case `Project`), would trigger a callback after the
top-level load completes, which you could use to immediately rewrite the
reference, add to `OldDataMonitor`, etc.

In the absence of that, your only option is to add a global initialization
hook which scans all build steps in all projects. Obviously this adds
startup overhead for everyone who installs your plugin, even if it is
unused. You could use a `GlobalConfiguration` (or simple `FileBoolean`) to
track whether the translation has been run before.

Another common use case is migrating `Secret` to `credentialsId`.
