[ARCHETYPE-539] Maven archetype:generate hangs on retrieval of archetype-catalog.xml even on offline mode

[jira-importer]

Franz Allan Valencia See opened ARCHETYPE-539 and commented

Steps to reproduce 

1.a Have slow connection 

1.b.Alternatively, simulate slow connection with crapify

1.b.1. Install crapify - npm install crapify -g

1.b.2. Run crapify - crapify --port=5000 --speed=1 start

1.b.3. Configure ~/.m2/settings.xml to use crapify

<settings>
...
   <proxies>
       <proxy>
           <id>crapify-proxy</id>
           <active>true</active>
           <protocol>http</protocol>
           <host>localhost</host>
           <port>5000</port>
       </proxy>
    </proxies>
...
</settings>

 

2. Execute 

$ mvn archetype:generate -DgroupId=com.example -DartifactId=example -Dversion=1.0-SNAPSHOT -o

  

Expected Behaviour:

The list of available archetypes would be shown to the user. 

Note: I believe in older versions, only the basic archetypes are shown like quickstart

 

Actual Behaviour:

Maven command hangs in this last last line:

[DEBUG] Searching for remote catalog: https://repo.maven.apache.org/maven2/archetype-catalog.xml

This is particular painful when a Nexus mirror is configured; for some reason seems to be much slower, taking ~2m to generate one project from archetype.

I would think that if the GAV are all defined, then this should work offline; and if the GA are defined, and version is set to LATEST or RELEASE, then it should merely need to download maven-metadata.xml for that GA. The full catalog should only be necessary if you are running in interactive mode and browsing available archetypes.
