Is there an Update Site for Lyo? [message #1077825]

Is there an update site that can be used to provision a target platform
with all the dependencies needed to work with Lyo? The downloads on
http://eclipse.org/lyo/download.php aren't in a form that's consumable
as bundles so it's unclear how one is expected to develop an
Eclipse-based application against the Lyo, or even how to exploit PDE to
easily manage the classpath/dependencies...

Hi Ed,

Eclipse Lyo doesn't include any PDE (plugins or features) as it doesn't contribute to the UI or Workbench. Instead it is a set SDKs, reference apps and samples to assist with OSLC development. We rely on Maven (m2eclipse) to pull in dependencies.

See http://wiki.eclipse.org/Lyo#Building_and_running_the_code

Hope that helps,
Steve

Steve,

So you don't expect anyone would ever use Lyo to develop Eclipse-based
(neither IDE nor RCP) applications? What kind of user interface would
you expect to be developed using Lyo? Only web-based ones?

Ed,

Actually I know of some people who have already used Lyo in this way (to develop Eclipse-based applications. It is just that the primary goal isn't to give developers features/plugins that provide contributions such as editors, validators, wizards, etc to assist with building OSLC-compliant tools. The primary needs we see are Java client and server based SDKs, that developers can easily leverage.

I have heard of a development team looking to contribute a tool that would help generate/provide the right client code based on introspecting an OSLC running server. Not sure when or if that will happen.

Ed,

As Steve has said, the Lyo project currently uses Maven, and we have builds published to repo.eclipse.org. I have to admit I'm not as familiar with Eclipse plugin development, but would something like Tycho help?

They'd need to convert all what's provided including all the libraries
Lyo relies on to bundles themselves...

Well yes, but if you expect those clients to be Eclipse applications,
providing the SDK in the form of bundles that can be used to build
editors and other tools in Eclipse seems essential, otherwise each
client is doing that themselves, which seems odd for a project hosted at
Eclipse...

Mostly I was just expecting bundles to be provided so I could build a
tool easily, without trying to bundlize everything Lyo provides and to
figure out which things are needed by the client code for that purpose...

A great many projects at Eclipse use Maven/Tycho for their builds,
almost of of them using it to build p2 update sites that provide bundled
frameworks directly useable in Eclipse applications.

It's mostly an issue of actually providing bundles which generally
amounts to little more than specifying in the MANIFEST.MF the
appropriate OSGi attributes.

Thanks, Ed. I opened an enhancement against Lyo:
