| Re: [tycho-user] Build Features separately |
Hi Jeff,
yes of course.
I created for every Feature a own Jenkins-job and a Parent-POM which contains the Modules (Feature + Plugin(s)).
So i'm using the Maven2/3 Job-type in Jenkins and using the Jenkins-SVN-Plugin for automatic checkout/update.
I'm using "mvn install" to install the artifact into the local-repository. Not deploy, we don't have a maven-artifact-manager.
All jobs sharing the same local maven-repository.
You're right, that the previous version is available.
When i re-build Feature1, the Feature2 is still available. Yes, but: Not the plugin he depends on!
There is a mistake im my exmaple. Not the Feature is the problem. It is the Plugin, that the Feature can't resolve.
I'm trying to give a better example:
The Jenkins-Job called "Basic" builds the Feature Basic with the Plugin XYZ-1.0.0.qualifier (let's say qualifier == 1220)
After the "mvn install" Maven will install the Plugin XYZ-1.0.0.1220 into the local repository.
Now the Jenkins-Job will build the Feature "Advanced" which depends on the same Plugin XYZ.
(Only depends, this Job will not build XYZ!)
Tycho/Maven will see that Plugin XYZ-1.0.0.1220 is available in the local-repository and will resolve it.
Again: After "mvn install" the Feature "Advanced-1.0.0.qualifier" (let's say 1230) is getting deployed too!
So far so good.
Now anyone re-builds Feature "Basic" which will re-build the Plugin XYZ!!
Tycho/Maven will change the qualifier to e.g. XYZ-1.0.0.1235 and will deploy it again! (and overwrite the old one)
Here it comes:
The Feature "Special" depends on Feature "Advanced". Maven/Tycho trying to resolve it and will see
that the Feature is in the local-repository. So he will trying resolve Feature Advanced-1.0.0.1230.
But he can't resolve it! Feature Advanced had the Plugin XYZ-1.0.0.1220 which is already overwritten by 1235!!
Resolve FAILED!
So yes, the Feature "Advanced" is still available. But not the Plugins that are declared in his feature.xml!
Hope this make it a bit clearer.
Thanks
MfG,
Timo L.

Can you describe your archictecture, do you deploy the artifacts, do you work with multiple Jenkins jobs ?

Hi all tycho-users,
my project contains several features, each of them has his own maven-build/jenkins-job.
I want to build separately because otherwise the build will take a long time to build but i want a fast feedback.
That's what jenkins/hudson (CI-Server) made for!!
The problem i'm facing is that i'm not able to build them separately, because of the Qualifier/SNAPSHOT.
For example:
I'm building Feature1 which contains Plugin1. Tycho will generate the qualifier "1219" for instance.
Now i'm building Feature2 which depends on Feature1! So tycho will generate a new qualifier (e.g. 1220) for Feature2 with the Qualifier of Feature1 (1219) in the feature.xml.
Now somebody change code in Plugin1 from Feature1. Feature1 will re-build -> new Qualifier -> 1921
Here it comes: I'm building Feature3 which uses Feature2! But Feature2 can't resolve his dependencies, because Feature1 has a new Qualifier! So the build fail!
So i'm always need to build in the right order (or remove the qualifier) but this can't be the solution. Do you guys making all full-builds? How do you deal with it?
Thanks alot in advance!
MfG,
Timo L.

"Legacy code" often differs from its suggested alternative by actually working and scaling.
