 [INFO] Generating project in Interactive mode

I am using Maven 3.0.5 version It is taking lot of time about 30 minutes to generate sample projects from the repository..

I dont know why it takes such a long time

Answer 1

After typing mvn archetype:generate maven scans remote repositories for all available archetypes so in case you connection is low it can take a long time.

I've made an experiment. I've occupied the internet channel (by downloading a torrent file) and run the command - and it seemed as it is hanging. But as soon as I paused the download maven listed out 858 available archetypes.

If you know for sure the spelling of the archetypeArtifactId you can use parameter -DinteractiveMode=false (official page).

Example:
mvn archetype:generate
-DgroupId=my.groupid
-DartifactId=my-artifactId
-DarchetypeArtifactId=archetype-artifactId
-DinteractiveMode=false

Answer 2

For the users trying to build using their local archetypes, an alternate way would be to just append -DarchetypeCatalog=local after your command.

This should look like

mvn archetype:generate -DarchetypeCatalog=local

to tell maven just looking type catalog from local instead of remote.
