It sounds to me like you might want to look into more advanced configuration of your CI server (or consider using a different one if yours doesn't provide the needed functionality). Most modern CI servers allow you to configure project dependencies directly within the CI environment. That is, using your example, a successful new build of B will automatically trigger new builds of A and D, which in turn will trigger a new build of E. One project I worked on recently even had the CI server set up (by way of some scripting) to set up and maintain the triggers automatically based on the ivy file for each project. If your dependencies don't change often, that level of automation may be unnecessary, but most CI servers make it very easy to set up cross-build triggers.

Each package is placed in a shared repo once its build from our CI. Our CI build every time someone commits. This of course yields a fair amount of packages - which in itself is not a problem. However, when a new package is build, it may be build with a newer version of its dependencies, whereas another package is still using the old version of the same dependency. for example: A:1.0.0 = (B:1.0.0 & C:1.0.0) D:1.0.1 = (B:1.0.1 & C:1.0.0) E = (A:1.0.0 & D:1.0.1) This will of course mean that we have conflict as we have B in 1.0.0 and 1.0.1 when building E. Since we cannot force E to use B in 1.0.1 (as this may cause problems for A), we are currently forced to validate that A works with B:1.0.1 and then create a new A:1.0.1 which has the same dependency versions of D. This makes sense in many ways - however when you have a lot of packages this gets a bit messy (and tiresome). I am thinking about creating a full-build target in our CI that will update all packages to use all the latest (it just need to build in a specific order). But I was wondering if A) I am doing something wrong, B) there are smarter ways to cope with this /matzon The content of this e-mail, together with any of its attachments, is for the exclusive and confidential use of the named addressee(s) and it may contain legally privileged and confidential information and/or copyrighted material.
