Hi,
Teiid Designer (TD) comprises part of jboss tools and provides an eclipse UI client
interface for
modelling and deploying virtual databases (vdbs) to a teiid server, which in turn is
deployed in jboss.
I have begun a discussion with mistria this afternoon on the possibility of a 3rd party P2
plugin
repository that would serve as part of the Teiid Designer target platform.
Background:
TD (unreleased version 8) uses a target platform of:
* http://download.jboss.org/jbosstools/updates/development/juno (JBT milestone build)
* http://download.jboss.org/jbosstools/updates/juno/SR0/ (Eclipse Juno Target Platform)
Thus, TD is a consumer of both the jbosstools TP and jbosstools features.
However, contained in the current TD codebase are the following wrapped plugins, ie.
wrapping
3rd-party built/released jars:
* net.jcip.annotations - jcip-annotations.jar
* net.sf.saxon - saxon9he.jar
* org.apache.poi - poi.jar, poi-scratchpad.jar, poi-contrib.jar
* org.jaxen - jaxen-core.jar, jaxen-jdom.jar, saxpath.jar
* org.mockito - com.springsource.org.objensis.jar, mockito-core.jar
* org.wsdl4j - wsdl4j.jar
* teiid_embedded_query - commons-cli.jar jansi.jar jline.jar
staxmapper.jar
jboss-as-cli.jar jta.jar teiid-api.jar teiid-engine.jar
teiid-client.jar teiid-admin.jar teiid-common-core.jar
All of these jars are obtained from external websites, including the teiid jars
(sf.net/projects/teiid).
Problem:
Everytime, an update of these jars is required, the new set of jars must be downloaded,
included in
the TD codebase and committed to the TD repository.
Since we fetch the jbosstools and eclipse plugins from the target platform, it would be
advantageous
if these wrapped-plugins could be broken out into their own repository, ideally with no
jars
actually in the code repository then automatically built and served as features in a P2
repository.
This P2 repository is then used by TD developers and TD build infrastructure.
For example, with the teiid jars, a new release is uploaded to sf.net by the teiid team,
downloaded
by TD dev, fully wrapped as plugin/plugins and added to the P2 repository.
Discussion so far:
* Mistria introduced me to the maven-dependency-plugin:get goal that could be executed
during the
generate-resources phase to download release jars build-time
* Mistria also pointed out his new maven plugin that can take several platforms as input
and produce
a single target file
* We agreed that this sounds very much like a jboss version of Eclipse Orbit and
considered the use
of this repository across all jboss projects rather than just TD (an external deps +
JBoss.org stuff
packaged as OSGi bundle in a p2 repo)
* Unlike Eclipse Orbit, we would wrap existing release jars rather than rebuild project
from source
* So a suggestion was made that given a project X normally has additional X.tools and/or
X.designer
projects, the latter should be responsible for shipping X as OSGI bundles
* Need approval since this represents an independent project. However, I would like to
limit it at
first to being a TD focused project until either other's find a use for it and/or it
proves itself
useful
* Consider a small independent P2 update site that is built manually and locally at first
then move
to automation when that is working
Questions for getting started:
* The hosting location for this P2 update site. Do I / Is it possible to have access to
download.jboss.org to upload such a site?
I would be interested to hear comments / opinions on any of the above and if it is
possible to host
such an update site please.
Many thanks for reading.
Regards
PGR
