New project created with Flex Mojo's archetype throws Cannot Find Parent Project-Maven Exception

Question

This is probably a silly question but I just cant seem to figure out. I'm completely new to flex and maven.

Maven 2.2.1: Maven 2.2.1 unzipped,M2_HOME set and repository altered to point to different drive location in settings.xml

Flex 4.0: Installed

Created a multi-modular webapp project using flexmojo:

mvn archetype:generate
-DarchetypeRepository=http://repository.sonatype.org/content/groups/flexgroup 
-DarchetypeGroupId=org.sonatype.flexmojos 
-DarchetypeArtifactId=flexmojos-archetypes-modular-webapp 
-DarchetypeVersion=RELEASE

with following options

groupId=com.test
artifactId=test
version=1.0-snapshot
package=com.tests

* Creates *

test
|-- pom.xml
|--swc -pom.xml
|--swf -pom.xml
`--war -pom.xml

Parent pom has swc, swf, war as modules.

Dependency is war->swf->swc.

With parent artifactId of swf, swc, war set to swf, swc, test respectively.

On executing mvn on test folder(for that matter clean or anything) I get this following error.

G:\Projects\test>mvn -e

Looks like its trying to download the project from maven's central repository instead of building it.

What am I missing?

Answer 1

It is a bit difficult to see without all the POM's.

However he parent relationship should not follow the dependencies.

All war,swf and swc should have the same parent, namely the pom.xml in the test directory.

Answer 2

What happens if you run mvn install from the root directory:

G:\Projects\test>mvn install
