Upstream and downstream projects like Jenkins


If this question overlaps with an already asked question please can you back link them to this query.

I would like to know if someone has implemented their builds that immitates the Upstream/downsteam feature in Jenkins (see - where you can have the project dependencies build first and then their builds trigger the dependent modules/projects to be built.

Just now the build execution might not be efficient as all projects and subprojects are built per git push / PR creation.

I’m also interested in an example that shows how a multi-module Maven project is implemented in this way, any links to documentation or already answered query on this topic will also be appreciated.

Is this possible using CircleCI 2.0 features?


I also want to set something like this up and am looking through the CircleCI discussion boards.

There is another thread on the same issue:

I’m working on setting something like this up. See my post at the end of the other thread.
