Have you provided the Pope with a list of the bugs that have been fixed
since the 2.1 shade plug-in?
Do they understand the great risk and horrible problems to which they
are exposing your organization by using a plug-in and an old Maven with
known bugs?
Good luck.
It is hard enough to fight the bugs that one creates without a corporate
structure making progress more difficult.

Sorry, I meant we do not have Shade 2.1 plugin. 2.0 is in our repository.

with Maven 3.1.1)
Unfortunately I don't believe that solves the problem. We actually do not have
the Shade plugin in our repositories and so I manually place it into our .m2
repository into the right place. The reason this is happening because our
organization is big and adding anything to our repository takes a papal bull
and a month of testing. I am trying to build an argument for our architects to
upgrade to Maven 3.1.1 which solves several bugs we're running into.
That is why I am doing all of this.
Now, I want to force it to look in .m2 before going anywhere else. I thought if
I used the -o flag to tell I to work offline it would do this, however it isn't.
Is there a way to force it to look in the .m2 for what it needs rather than
having to go to mavencentral?

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/release
s) 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?
