The maven support in NetBeans 7 have bean moved to Maven 3...if user opened a maven 2 project, it should help user to upgrade the deprecated configraution in pom....

Would be useful. There are a number of different things to do, though; most are handled best by e.g. versions-maven-plugin.
Comment 2 lmorissette 2010-11-07 01:13:01 UTC
I also agree that we need such feature. plus doing a quick search of Maven migration show a couple of tips about I think maybe the first step (as you may have figured out :) ) migh be to see if there is a migration guide out there somewhere that we could use

well i'll be interested in this question and will try to do some research

This would be a great place to contribute patches - is largely self-contained. It should also be possible to create hints in an external plugin, which could be integrated into the official IDE builds when stabilized.

Rather than adding hints to the pom.xml editor, another approach is to create an org.netbeans.modules.maven.api.output.OutputProcessorFactory which would take note of an actual warning reported during the build, and create a hyperlink offering to fix it. This would be more appropriate for a misconfiguration which cannot clearly be identified with a particular line in the POM.

First I would be interested in hearing what sorts of compatibility issues users are actually running into, and how much work it is understand the issue and find the fix.

I have made a couple of improvements in 7.1 relating to model building problems, which would be helpful for compatibility issues relating to that, which seem common - e.g. <plugin> without <version>.

1. Warnings in the Maven output about model building problems now hyperlink to the POM.

2. The POM editor now shows warnings (and errors) from Maven validation, refreshed after you save changes.

Integrated into 'main-golden'
User: Jesse Glick <>
Log: Hyperlink model building problems, so you can at least see where in the source POM the problem lies.
Does not currently attempt to map repository model IDs to known source projects, though it could.
(Maven itself will report the source POM only if there are suitable <parent> links.)
Mentioned in bug #191116 comment #3.
Comment 7 Milos Kleint 2012-02-17 14:14:59 UTC
reading the MavenProject instance with ModelBuildingRequest.VALIDATION_LEVEL_MAVEN_3_0 should be able to collect all model related warnings, along with line and column numbers I think..
Comment 8 Jesse Glick 2012-02-20 20:29:58 UTC
We already show warnings in the POM editor as of 7.1 (a5580fffe252 for comment #5 item #2). But there are no hints to help solve those issues.
