sorry for the delay, time is missing lately introducing new status, with pseudo-pom property and so on seems irrealistic, at least to me: the concept is interesting, but I doubt it can fit into the actual code Perhaps with Maven 3.2 (precise version and feature definition hypothetical), since decoupling dependency resolution in a work in progress because really needed: started in Maven 3.0 with a first extration into Aether, will continue in 3.1 with some experience in evolutions. An evolution like yours could be imagined only after, IMHO
But looking at your actual pipeline, perhaps we can imagine something with actual Maven features Le dimanche 6 janvier 2013 10:18:18 Gábor Guta a écrit : > Hi Hervé, > > > can you explain the ant/ivy build pipeline implementing promotion you did > > with the help of my team mates? > > Context: we have several modules which are built on top of each other. > The build pipeline: > - developer commits his/her changes to the SVN ok, standard SNAPSHOT source > - the Jenkins server checks out from SVN, compiles and runs the unit > tests; finally, the jar artifacts are created and published with > "integration" status ok, publishing the SNAPSHOT binary to an integration repository > - a Jenkins job retrieves this artifact from an Ivy repository and > checks out secondary tests from the SVN; runs the secondary tests; if > all tests pass, the description of the artifact is re-published with > "milestone" status this one can be done by copying the SNAPSHOT artifact from integration repository to a milestone repository > - other jobs grab only the artifact if it has least "milestone" status other jobs, which refer to the SNAPSHOT with its "-SNAPSHOT" in the version only use the milestone repository, not the integration one: fine > - on the end of the pipeline "milestone" artifacts can be promoted > manually to "release" if the manual tests are successful that's the tricky part: you're changing a SNAPSHOT artifact to a release do you expect build reproducibility of the release? (even if your objective is to promote the pre-built binary, not to deploy a rebuild) what about copying the binary into the same repo, ony changing its version coordinates: of course, its content (META-INF/maven/$gid/$aid/pom.xml) won't be consistent > - other loosely coupled projects reference only to artifacts with > "release" status ok, they reference release versions in the release repo > > Promotion is handled completely by the apache-ivy. It allows you not > only to reference snapshot as maven do, but you can specify > "latest.integration" or "latest.release" as version. without any version? and not "latest.milestone"? with Maven and previous repo, you can write an unbounded range: [minimal,) activating integration consists in adding the integration repo Notice: you might require separate integration or milestone repos to distinguish which dependency can include milestone would that make sense?
