Affects Version/s: 2.2.1
Fix Version/s: None
[if only this was a later version of JIRA I'd have not lost all of what I just typed, as I could use Mylyn instead of the web UI. here goes again...]
The challenge of using a different artifact instead of the one that is specified in a POM that you are consuming is not an easy one.
Examples where this hits uses is:
- the artifact name and packaging changes that Spring made at 2.5.6A (which was a big improvement)
- wanting to use SLF4J instead of Apache commons logging (i.e. use something that provides the same API, but is an entirely different project)
- wanting to use your own derivation of a public artifact
- wanting to use a woven/instrumented version of a public artifact
The current approach to replacing, say org.springframework : spring-beans with org.springframework : org.springframework.beans is to do ('scuse the shorthand):
to exclude it, and then globally include the replacement using:
This is error prone, and could be made far easier by an extension to dependencies, which would remove the need to know what artifacts (jersey-spring in the above example) use the artifact that you are replacing. Here's how it would look:
- Nothing is specified in <dependencies> so no artifacts are globally added where they may not be needed. This means we can develop a project wide parent pom.xml.
- Artifacts can have been split and merged
- Derived artifacts, such as instrumented ones can easily be substituted, and could be selectively substituted using profiles.
