----------------------------------------------
Summary: Generate snapshot packages through Jenkins
Key: CASSANDRA-13487
URL: https://issues.apache.org/jira/browse/CASSANDRA-13487
Project: Cassandra
Issue Type: New Feature
Components: Build
Reporter: Stefan Podkowinski
Assignee: Stefan Podkowinski
Creating packages through the new docker based build scripts now work pretty
much independent from any local environment, as long as docker is available,
e.g. also on Jenkins. Having daily snapshots available for deb/rpm artifacts
would enable us to provide users dev-releases for testing and validating fixes.
I've created a branch for the Jenkins integration, which can be found here:
https://github.com/spodkowinski/cassandra-builds/tree/jenkins_debrpm
The major issue I'm currently struggling with is the handling of the actual
version value. We need to find a way to have Jenkins recognize the correct
version for the branch being build. Also we must create $version-SNAPSHOT
packages, as builds are not official releases and we should not have any
packages for versions that aren't published yet.
The Debian build process will use the version defined in {{debian/changelog}}.
Adding a -SNAPSHOT suffix for the version should work, but this has to be
handled manually and care must be taken to change the value back again for a
regular release.
With RPMs, the version must be set for {{cassandra.spec}}, which is currently
done by running {noformat}rpmbuild --define="version ${CASSANDRA_VERSION}" -ba
./redhat/cassandra.spec{noformat}, where the version is passed as a parameter
by {{build-scripts/cassandra-rpm-packaging.sh}}. Maybe we could grep the
version from build.xml here?
So I wonder if there any way we can keep track of the version in a single
place, such as build.xml or CHANGES. Afterwards we also need to enable a
SNAPSHOT mode, maybe by setting a Jenkins environment value.
