Failed to resolve version for org.apache.maven.archetypes

I have configured maven3.0.3 in my local machine. Have installed m2e eclipse plugin. But when i try to create a new maven project using maven-archetype-webapp, i get the following exception.

 Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:RELEASE    from any of the configured repositories.
 Could not resolve artifact org.apache.maven.archetypes:maven-archetype- webapp:pom:RELEASE
 Failed to resolve version for org.apache.maven.archetypes:maven-archetype- webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype- webapp/maven-metadata.xml in local ([HOME]/.m2/repository)
 Failed to resolve version for org.apache.maven.archetypes:maven-archetype-  webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype-  webapp/maven-metadata.xml in local ([HOME]/.m2/repository)

I do some processing behind a proxy and the proxy configurations are updated in {HOME}/.m2/settings.xml and M2_HOME/conf/settings.xml.

The archetype generate command works fine in command line. It downloaded the dependencies through proxy.

Any help is greatly appreciated.

Edit 05-10-2012 While creating a new Maven Web project in eclipse, the archetype "maven-archetype-webapp" version is displayed as RELEASE. Is this in anyway linked?

I had the same problem. I fixed it by adding the maven archetype catalog to eclipse. Steps are provided below:

1. Open Window > Preferences
2. Open Maven > Archetypes
3. Click 'Add Remote Catalog' and add the following:
   • Catalog File: http://repo1.maven.org/maven2/archetype-catalog.xml
   • Description: maven catalog

I found the following tutorial very useful.

Step1: The maven command used to create the web app: mvn archetype:generate -DgroupId=test.aasweb -DartifactId=TestWebApp -DarchetypeArtifactId=maven-archetype-webapp

Step2: The following entry was added onto the project's pom.xml.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.0.2</version>
    <configuration>
    <source>1.6</source>
    <target>1.6</target>
    </configuration>
</plugin>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-eclipse-plugin</artifactId>
    <configuration>
    <wtpapplicationxml>true</wtpapplicationxml>
    <wtpversion>1.5</wtpversion>
    <downloadSources>true</downloadSources>
    <downloadJavadocs>true</downloadJavadocs>
        <classpathContainers>
            <classpathContainer>
                org.eclipse.jst.j2ee.internal.web.container
            </classpathContainer>
            <classpathContainer>
                org.eclipse.jst.j2ee.internal.module.container
            </classpathContainer>
        /classpathContainers>
        <additionalProjectFacets>
            <jst.web>2.5</jst.web>
            <jst.jsf>1.2</jst.jsf>
        </additionalProjectFacets>
    </configuration>
</plugin>

Step3: Run the maven command to convert into eclipse project format. mvn eclipse:clean eclipse:eclipse

Step4: Import the project onto eclipse as Existing Maven project.

If you are using eclipse, you can follow the steps here (maven in 5 min not working) for getting your proxy information. Once done follow the steps below:

1. Go to Maven installation folder C:\apache-maven-3.1.0\conf\
2. Copy settings.xml to C:\Users\[UserFolder]\.m2

3. Modify the proxy in settings.xml based on the info that you get from the above link.

   <proxy>
     <active>true</active>
     <protocol>http</protocol>
     <host>your proxy</host>
     <port>your port</port>
   </proxy>
   

4. Open eclipse

5. Go to: Windows > Preferences > Maven > User Settings

6. Browse the settings.xml from .m2 folder

7. Click Update Settings

8. Click Reindex

9. Apply the changes and Click OK

You can now try to create Maven Project in Eclipse

Read carefully about the reason.

"Failed to resolve version for org.apache.maven.archetypes:maven-archetype- webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype- webapp/maven-metadata.xml in local"

So all you need to do is download the maven-metadata.xml to your {HOME}.m2\repository

That's it.
