Install Maven Archetype

Question

I have created a Maven archetype from an existing project. I have even installed the archetype in my local repository and used it to create a new project. Everything went pe

Answer 1

Few clarifications here:

// installs the project to your local repository (jar, archetype, etc.)
mvn install
// AND updates archetype catalog
mvn install archetype:update-local-catalog
// calls plugin archetype goal crawl
mvn archetype:crawl

Crawl goes through Maven repo and CREATES catalog.

If you wish to use archetype interactively, you either need to call if with full coordinates or have it listed in the catalog.

// use local catalog
mvn archetype:generate -DarchetypeCatalog=local
// full coordinate set, my example
mvn archetype:generate -DarchetypeGroupId=pl.lafk -DarchetypeArtifactId=simple-testng-quickstart -DarchetypeVersion=1.0 -DgroupId=pl.lafk -DartifactId=sample-app

When you call mvn deploy you do all that install does plus push the package to remote repository - if you have it configured.

Link I used was Maven site for plugin: https://maven.apache.org/archetype/archetype-packaging/index.html

Additionally: mvn archetype:help

Answer 2

Hi it is a late response, but I had the same problem that I didn't find a clear instruction how to share an archetype. So I hope that the following will help someone who struggles as lot as I did:

• Develop your archetype: Either alone or with mvn archetype:create-from-project. There are enough instructions in the internet which explain how to do that.
• Enter the distribution-management element in your pom.xml where the nexus-repository you want to publish/share your archetype must be defined. The link with the maven/settings.xml for the connection properties and so on is made with the id element and not with the url element.
• call "mvn clean install" with all options you want to install the archetype in your local maven repository
• call "mvn deploy" and maven will do the rest and update your remote archetype-catalog.xml by itself!
• to test that the archetype is really recognized call "mvn archetype:generate -Dfilter=[your archetype artifactid]" and it should be in the list.

For those looking for more recent info: The way to use an archetype catalog in a custom repository for the current version of the plugin (see date of this comment), is defining in your setting (~.m2/setting.xml in Mac) the repository with id "archetype":

<repository>
    <id>archetype</id>
    <name>archetype_company_repo</name>
    <url>http://your.company.com/nexus/content/repositories/releases/</url>
</repository>

Maven archetypes are artifacts just like any other project build artifact. You deploy them to your repository with the Maven deploy command.
