Snapshot/integration builds on sbt community repo

[eugene yokota]

Hi all,

I'd like to start a discussion on implementing snapshot/integration build support on sbt community repo,

and potentially other Ivy repositories.

For security and caching reasons, Josh and I are interested in pursuing the unique version approach,

in which the snapshot versions are appended with unique string, like date and/or time.

Here's the idea I have for sbt-ivy-snapshot plugin.

- It defines uniqueVersion key.

- When uniqueVersion is true, it replaces -SNAPSHOT in version with current date and time in UTC e.g 0.8.2-SNAPSHOT => 0.8.2-20120525173400.

- It also changes deliverConfiguration's status to "snapshot" and adds a custom status called snapshot to ivyXML.

When the build user wants to use your snapshot, they would say addSbtPlugin("com.example" % "sbt-foo" % "latest.snapshot").

If they dont' care if it's a release or snapshot they can also say "latest.integration". See [1] for more info.

What do you think?

Many projects have multiple active lines of development. How would you specify which snapshot that you want? 

For example, say sbt-foo has two active lines of development: 0.7.x and 0.8.x. How would you specify that you need an 0.7 snapshot instead of an 0.8 snapshot?

For plugin development, I was thinking single track of snapshot would be ok.

But if I think about it, you probably could embed this information in info.status.

- It also changes deliverConfiguration's status to "0.8.2-SNAPSHOT" and adds a custom status called snapshot to ivyXML.

This way the build user can say:

addSbtPlugin("com.example" % "sbt-foo" % "latest.0.8.2-SNAPSHOT")

Maybe it's just my Maven bias talking, but shouldn't:

  addSbtPlugin("com.example" % "sbt-foo" % "latest.0.8.2-SNAPSHOT")

be identical to:

  addSbtPlugin("com.example" % "sbt-foo" % "0.8.2-SNAPSHOT")

Or is this one of those subtle and tricky ways that Maven and Ivy are different?

"latest.0.8.2-SNAPSHOT" says give me the latest artifact who's status
is 0.8.2-SNAPSHOT, regardless of the version.

"0.8.2-SNAPSHOT" says give me the artifact whose version is 0.8.2-SNAPSHOT.

I am trying to come up with a way that allows plugin authors to
publish snapshots without involving jar overwrites.

So, yes, both tricky and subtle.

Thanks,
