I am using the maven dependency plugin get goal to download an artefact from nexus. I can use it to download jar as per below
mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -DrepoUrl=http://nexus.url/nexus/content/groups/public-all/ -Dartifact=groupId:artifactId:version:jar -Dtransitive=false -Ddestination=/my/path
To download a war I can use
mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -DrepoUrl=http://nexus.url/nexus/content/groups/public-all/ -Dartifact=groupId:artifactId:version:war -Dtransitive=false -Ddestination=/my/path
I am however failing to download an ear using the following
mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -DrepoUrl=http://nexus.url/nexus/content/groups/public-all/ -Dartifact=groupId:artifactId:version:ear -Dtransitive=false -Ddestination=/my/path
The output of the above command is as per below

I have confirmed that the ear is indeed present in Nexus. The above command runs successfully but the ear is not actually downloaded.
What is wrong with the above command to download the ear? How can I download an ear file from Nexus using the mvn command?
Do note that I have replaced the actual groupId, artifactId and versions in the code above with their respective words.

TL;DR: How does one build a Gluon app that's part of a larger multi-module project?
I have a multi-module Mave project (that is, my top-level POM has "<packaging>pom</packaging>"). The project contains a bunch of libraries and related sub-projects, one of which is a Gluon app that will be what my actual users install. (The rest of the project is all the cloud-hosted plumbing that the client app connects to.)
When I try to build the Gluon app, per the Gluon documentation, I am getting the following error:
mvn gluonfx:build

If I run Maven so that it only builds the Gluon application instead, like this:
mvn gluonfx:build --projects "app-gluon" --also-make
I get basically the same error. If I cd to app-gluon first, I get a different error (and I didn't expect this to work anyhow):

So my question is: how does one build a Gluon app that's part of a larger multi-module project?
If you have a multi module project, and your app module depends on other modules, you need to publish those modules to a repository, so the app module finds them, like any other third party dependency.
Typically, for local development, you can simply use mvn install from the root folder to deploy your project locally. Of course, for distribution, you should consider publishing them to a reachable repository.
Make sure all your modules are deployed to your ~/.m2 repository.
Then you can run from the root:
mvn gluonfx:build -f app-gluon
or enter in the app-gluon folder:
cd app-gluon
mvn gluonfx:build
And remember that every time you make any change to the other modules, you will need to publish them again before building the native image.
Also, since you can run your app on the JVM, before building the native image (which takes a couple of minutes), you can simply run and test:
mvn gluonfx:run
and if that works fine, do the native image build.
I am trying to build Metasfresh ERP backend (server-side) suite https://github.com/metasfresh/metasfresh/tree/master/backend and my maven build stops at the project https://github.com/metasfresh/metasfresh/tree/master/backend/de.metas.adempiere.adempiere/migration because of missing resrouces required by the maven-assembly-plugin.

So - this is very strange thing with this project. Maybe there are some administrative/commercial/organizational issues in this open source project and they are keeping forbidden some necessary files intentionally.
My question is - how can I ask maven plugins to skip missing resources? And just see what is happening?
Maybe I can download maven-metadata.xml, remove the entries for which there are no versions and then hope that maven-assembly-plugin will use local (handcrafted) mave-metadata.xml?
de.metas:metasfresh-assemblies:jar:5.159.1-21669+master's POM contains:
...
<parent>
<groupId>de.metas</groupId>
<artifactId>de.metas.parent.general</artifactId>
<version>5.159.1-21669+master</version>
...
</parent>
...
but, as you found, there is no such artifact.
This is also not a resource (as in src/[main|test]/resources), but a parent POM. You can't "skip" parent POMs, i.e. you can't build child POMs if the parent is not available. This is like trying to compile a sub-class if the super-class isn't available in the classpath.

It looks like this is more of a Maven issue than it is a Camel issue. I put in the default .m2/settings.xml file (before I had a mirror configured for my companies Nexus repository. I thought that might be messing things up so I took it all out). Out of desperation I even tried adding in the plugin repository from here http://camel.apache.org/maven-2-snapshot-repository-in-pom.html but that did not work.
Read the readme file how to run the examples.
Some examples run using mvn camel:run and others using mvn exec:java and what else.
And you run from the master branch in the source code. Instead you should download a version of Camel such as the latest 2.16.2 and use that. It ships the examples in the examples directory: http://camel.apache.org/download
If you run from master branch in the source code. You need to rebuild Camel first, see building: http://camel.apache.org/building.html
I've tested myself, and putting the plugin 2.16 don't solve it neither.
But in readme, I found this :
We have described this in more details at the Camel twitter documentation:
http://camel.apache.org/twitter
You will need to compile this example first:
mvn compile
To run the example type
mvn exec:java
Then open a browser to see live twitter updates in the web page
http://localhost:9090
Worked for me, I hope it will work for you too. I'll investigate the problem with the plugin that doesn't seems to export the prefix latter.
