How Can I Work with Transitive Dependencies?
The Spring Cloud Contract plugins add the tasks that create the stubs jar for you. One
problem that arises is that, when reusing the stubs, you can mistakenly import all of
that stub’s dependencies. When building a Maven artifact, even though you have a couple
of different jars, all of them share one pom.xml file, as the following listing shows:
├── producer-0.0.1.BUILD-20160903.075506-1-stubs.jar
├── producer-0.0.1.BUILD-20160903.075506-1-stubs.jar.sha1
├── producer-0.0.1.BUILD-20160903.075655-2-stubs.jar
├── producer-0.0.1.BUILD-20160903.075655-2-stubs.jar.sha1
├── producer-0.0.1.BUILD-SNAPSHOT.jar
├── producer-0.0.1.BUILD-SNAPSHOT.pom
├── producer-0.0.1.BUILD-SNAPSHOT-stubs.jar
├── ...
└── ...There are three possibilities of working with those dependencies so as not to have any issues with transitive dependencies:
-
Mark all application dependencies as optional
-
Create a separate
artifactidfor the stubs -
Exclude dependencies on the consumer side
How Can I Mark All Application Dependencies as Optional?
If, in the producer application, you mark all of your dependencies as optional,
when you include the producer stubs in another application (or when that
dependency gets downloaded by Stub Runner), then, since all of the dependencies are
optional, they do not get downloaded.
How can I Create a Separate artifactid for the Stubs?
If you create a separate artifactid, you can set it up in whatever way you wish.
For example, you might decide to have no dependencies at all.
How can I Exclude Dependencies on the Consumer Side?
As a consumer, if you add the stub dependency to your classpath, you can explicitly exclude the unwanted dependencies.
