Michael Osipov commented on MNG-7283:
-------------------------------------
Your approach is wrong aka you did not read/try hard enough. What you want to
have an interface where you load your implementations on the fly which reside
on the classpath. You are best to implement the {{ServiceLoader}} and load all
providers dynamically. You can identify your providers by URIs, e.g,
{{mq+aws://...}}, boils down to {{<protocol>+<transport>://...}}, same is done
in Maven SCM. You can either bundle all provider implementations or create POM
module which will create assemblies with whatever you need.
Upshot: There is no need to add dependencies at build time dynamically.

> Key: MNG-7283
> URL: https://issues.apache.org/jira/browse/MNG-7283
> Project: Maven
> Issue Type: Wish
> Components: Dependencies
> Reporter: wangjie
> Priority: Major
> Fix For: wontfix-candidate
>
>
> *1、background*
> as we all kown, each cloud environment has different component
> implementations. For example: The message queue components of AWS and Alibaba
> Cloud are similar in function, but different in implementation.
> we are try to build a unified API specification, developers only need to
> introduce unified standardized APIs for these components when developing.
> When the project is built and deployed on different clouds, we will
> automatically introduce the implementation dependencies of different
> components under different clouds for the project.
> *2、issues*
> Due to the above reason, we hope to add some dependencies when maven starts
> to build the project. After reading the documentation and google related
> issues, I found that maven does not support this feature(I don’t know much
> about maven. If maven supports this feature, please share with me. Thanks in
> advance).
> If maven does not support adding dependencies at the beginning of the build,
> can the community consider supporting this feature?
