Adding comments to dependencies in POM
I have in the past wasted hours of effort trying to weed out dependency issues where something has been added for reasons unknown. Removal leads to breakage. It would be helpful if, inside a POM, it were possible to add a comment element to a dependency. I realise this is possible as an XML comment, however having a POM field would let documentation engines record the comment. The same could be said for dependencies inside dependencyManagement. It would of course have the side effect of auto completion within IDEs showing authors how to officially comment on the reason for that work. An idea. James
Re: Adding comments to dependencies in POM
A very good idea I think. Please add it as an improvement in JIRA and it could be implemented in a future pom model version. /Anders (mobile) Den 27 aug 2014 09:13 skrev James Green james.mk.gr...@gmail.com: I have in the past wasted hours of effort trying to weed out dependency issues where something has been added for reasons unknown.

Did you try increasing memory for maven through MAVEN_OPTS, maybe something like -Xmx1024m or more ?

Re: Adding comments to dependencies in POM
I think it should be solved with a separate namespace, so the model parsing stays pure without metadata irrelevant for Maven. And it should already work right now, no need for the pom xsd to change, since the Maven pom-parser should ignore these kinds of elements/attributes.

Atomic deploy at end to repo manager like Nexus
