Thanks Curtis and everyone.
I have a follow up question around the same thing build.
The command line I am using: maven clean install
Our 3.1.1 maven build is having issues finding the plugins in our .m2 directory
unless I specify on the command line -Pmavencentral which is defined in our
.m2/settings.xml as such:
<profile>
<id>mavencentral</id>
<repositories>
<repository>
<id>mcentral</id>
<url>http://sd-repo-2.eng.qpass.net:8081/nexus/content/repositories/central</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>mcentral</id>
<url>http://sd-repo-2.eng.qpass.net:8081/nexus/content/repositories/central</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
Which is our proxy to the public internet mavencentral server.
I have tried using the -o and -U switches at the command line when executing
without the -Pmavencentral and I receive the following:
[ERROR] Plugin org.apache.maven.plugins:maven-shade-plugin:2.1 or one of its
dependencies could not be resolved: Cannot
access qpass-nexus-hosted-releases
(http://pd-repo2.eng.qpass.net:8081/nexus/content/repositories/releases) in
offline
mode and the artifact org.apache.maven.plugins:maven-shade-plugin:jar:2.1 has not
been downloaded from it before. -> [Help 1]
I want it to look only in the .m2 repository. Is there another -D setting I
need to speciy? Is there some place I should be looking to see for conflicting
settings?

Hi John,
You might be able to use profiles to define a different version of
maven-shade-plugin depending on the version of Maven being used. However, some
caveats:
1) There is no explicit profile activation for Maven version. The hack people
use is to activate based on the existence of a property known only to e.g.
Maven 3.x. I am not sure what a good property would be for Maven
3.1 specifically (i.e., not known to 3.0.x), but one probably exists.
2) When it comes to profiles, as Stephen Connolly likes to say: "that way madness
lies." This hack will get your build done for you, but it is a hack, and you should
never forget that it is a hack. Or to put another way:
it's technical debt. When the debt must be paid is unclear, but e.g. if the
maven-shade-plugin produces a different binary result depending on which
version you use, then you may run into apparently bizarre problems with users
who built using Maven 3.1.1 rather than an older version, or vice versa, and it
may take you some time to diagnose *why* it's happening
(surprise: it's because a different version of maven-shade-plugin got
selected!), and so on.
Such problems are why the other posters in this thread are encouraging you to
just choose a version of maven-shade-plugin that works for you. You
*can* put into your POM that it requires a certain minimum Maven version [1],
and Maven will (IIRC) just fail fast if the version is too old. That is a lot
less mysterious than some subtle inconsistency in shaded artifact build
results. And you'll get truly repeatable builds which are one of the fabulous
benefits of a well-structured build system.
Regards,
Curtis

We are getting build failures when using 3.1.1 and the 2.0 shade plugin.
It seems to be a documented issue:
https://issues.apache.org/jira/browse/STANBOL-1212
So I wanted to be able to have the same parent pom for our builds that
still require 3.0.5 which currently sets it to 2.0 and does not run
into this error.

Agreed however I need to support two builds in our environment one
that uses Maven 3.0.5 and one that does 3.1.1 without having to
change
the file every time.
Sorry for asking the obvious question, but what prevents you from
specifying version [2.0] or whatever and using that with both 3.0.5
and 3.1.1? Is there some incompatibility I am unaware of presently?
