从（Eclipse）项目创建Maven工件，并从中生成新项目

Question

I have an Maven (eclipse) Project, which i want to convert to an Maven Artifact - so that others can generate new Project from it.

To create Artifact i did:
cd to my proj dir where pom.xml exists

mvn install

After this i can see that
.m2\\repository has my project added.
But <user_home>\\.m2\\archetype-catalog.xml - did not have the archetype added.
So, i added manually as follows:

<archetype>
      <groupId>com.whatever</groupId>
      <artifactId>myapp</artifactId>
      <version>1.0.0-BUILD-SNAPSHOT</version>
      <repository></repository>
</archetype>

Now, i am not sure what to give in tag, as this is a local repository.

But, i am unable to generate a new project using:

mvn archetype:generate -DarchetypeCatalog=local

It asks me to choose the archetype, but after that i get error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:2 .2:generate (default-cli) on project standalone-pom: The desired archetype does not exist (com.whatever:myapp:1.0.0-BUILD-SNAPSHOT) -> [Help 1]

What step am i missing?

Answer 1

You need to run the archetype plugin from within your original project to generate an archetype descriptor.

Here is an example of how to do this.
