Error executing Maven archetype generate command to create a Opendaylight project structure

Question

When I execute this:

 mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype \
-DarchetypeRepository=http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/ \
-DarchetypeCatalog=http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/archetype-catalog.xml

I got the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.0.1:generate (default-cli) on project standalone-pom: archetypeCatalog 'http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/archetype-catalog.xml' is not supported anymore. Please read the plugin documentation for details. -> [Help 1]

And help1 looks like this:

[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoFailureException

which hasn't been update for a long time.

First, I removed backslash and whitespace, obviously it didn't work. I thought it may be the parameter of archetypeCatalog, so I ran this:

mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype -DarchetypeCatalog=remote -DarchetypeVersion=1.1.2-Beryllium-SR2

I got a error like this:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.0.1:generate (default-cli) on project standalone-pom: The desired archetype does not exist (org.opendaylight.controller:opendaylight-startup-archetype:1.1.2-Beryllium-SR2) -> [Help 1]

The tutorial mentions that OpenDaylight maintains its own repositories outside of Maven Central, which means maven cannot resolve OpenDaylight artifacts by default. So I did as tutorial with following command:

cp -n ~/.m2/settings.xml{,.orig} ; \ wget -q -O - https://raw.githubusercontent.com/opendaylight/odlparent/master/settings.xml > ~/.m2/settings.xml

I even tried this:

cp -n ~/.m2/settings.xml{,.orig} ; \ wget -q -O - https://raw.githubusercontent.com/opendaylight/odlparent/stable/beryllium/settings.xml > ~/.m2/settings.xml

The settings.xml files just look the same. I have seen some similar issues these days. As a noob of both maven and opendaylight, I have no idea about what to do next step? I just want to generate an opendaylight arachetype to start a toaster.

Thank you for your help. Here is my maven inforamtion:

With maven-archetype-plugin 3.x it is not possible anymore to specify the repository as commandline argument (for consistency and security reasons).

So you have 2 options:

• Follow the new instructions
• Lock the version of the plugin to 2.4
