About Maven3 M2Eclipse Plug-in Versioning Problem
Hi,
At first, thanks for your attention and time to read.
In our enterprise applications we use MyEclipse 8.5 with
M2Eclipse maven3 plug-in support. Before begining to use maven3, with maven2 we
could specify a variable for the application version in the parent pom, so that
in the child poms we could able to specify the version by the same variable.
That helps us saving our time for updating version number in each project
upgrade and for reusability.
I hope I can clearly demonstrate the problem as the
following piece of code for pom.xml’s.
Now the problem is in maven3 (m2eclipse) it gives a warning
that says “version must be a constant instead of a variable”. I have been
trying lots of variations such as moving out the <version> tag or
swapping the expressions between <projectVersion> and <version>
tags or the other suggestions from the different forum sites, etc.. However,
the solution never comes up.. Maybe I am doing something wrong, but could not
find out yet.
Any help would be appreciated,
Many thanks in advance,
Bariscan
BTW, you can check the case from here:

A POM deployed to a repository must be self-contained in the way that
all information required to process it (e.g. calculate the effective
POM) must be present in the POM.
This does not hold for a POM referencing its parent via an external
property. Until Maven provides support to (partly) interpolate
properties before deployment, using properties for POM coordinates is an
anti-pattern that enables deployment of broken POMs, i.e. that can't be
used during dependency resolution as we have already seen in the past
for stuff in central.
Regarding easier version maintenance for multi-module projects, right
now I can only suggest to use the Release Plugin and to vote for MNG-624.

No worries... though I need to call a vote to get a 3.0-beta-1 compatible
version published

Oh, and I likely should have mentioned the
http://mojo.codehaus.org/versions-maven-plugin/
(sorry Stephen ;-) )

//did you try setting the necessary properties in settings.xml or profiles.xml e.g.?

You were relying on a bug.
the following xpath:/project/parent/groupId,
xpath:/project/parent/artifactId, xpath:/project/parent/version,
xpath:/project/groupId, xpath:/project/artifactId, xpath:/project/version
cannot ever reference a property as they are all evaluated before the model
is available.
