Re: [cross-project-issues-dev] Anyone out there using Tycho? 
Orbit produces p2 repositories for their builds. To consume them from
Tycho, you need to add <repository/> element with layout=p2 and
appropriate repository url to the parent pom.

Thanks. I see the message "Using compile source roots from
build.properties", guess my trouble was that the old ant files weren't
being parsed properly. have renamed them to antbuild.*, and copied a
basic PDE build.properties file in it's place. That took care of the "no
code to compile" issue.

Now I just need to figure out getting Orbit bundles recognized and
compiled against.

Eric,

Tycho uses the build.properties file and the MANIFEST.MF files
produced by the PDE plugins.  If you have items setup there, it will
use the information from the build.properties files to identify where
the source folders are.

Chris,

Sorry about the delay replying. I didn't see your reply until I got
back from vacation, and have just got back into the swing of things
with this particular project.

What do you mean "auto-generate" ?

I believe most projects at eclipse.org <http://eclipse.org> are
using the manifest-first approach with Tycho... so things just work.
Are you expecting your MANIFEST.MF's to be generated also?


by "auto-generate" I was referring to the automatic generation of the
POM files. For multiple (some as yet unidentified) reasons, Tycho was
only generating a minimal POM file.  It specified the Tycho plugin,
modules, and basic project tags, however could not build because
maven found no source, test source, or manifest.

After further experimentation it seems that the project files are
parsed for some of the metadata for POM generation (manifest location
for instance, but not the source tree), however, I'm still having to
walk through the POM syntax and manually modify the POM in order to
get maven to compile the code (This was NOT the case in the example).
It appears that this is the result of our project not using PDE to
build, and relying upon an external Ant process for the production
build. I am surmising that my troubles are the result of the PDE
project files not containing key pieces of metadata.

Furthermore, the documentation for Maven 3.0/Tycho is fairly sparse,
so I've had to rely upon examples and experimentation to make
progress. These were the initial reasons for my query... so I could
look at the POM files generated for other projects and thereby cobble
together something that would work with our existing project structure.

The purpose of this exercise is to evaluate whether we could utilize
Tycho to generate our OSGi bundles with a "manifest-first" approach
with minimal impact upon our overall build process, and to identify
what will need to change in our project structure and processes.
Secondary to the above is to determine the feasibility, and
desirability for incrementally migrating the rest of our processes
over to Maven.

I appear to have a build functioning well enough that I am now
failing due to missing dependencies (which are all local to the
target platform, but many are not in any P2, or Maven repository).
I'm working on putting them into a local P2 to make headway. In
general I am confident that we could use Tycho, the question now is
what will it take to do so.
