ejb-javaee6 with error when generated by eclipse

When I create an ejb project through ejb-javaee6 archetype in Eclipse I get the following errors:

Description Resource Path Location Type Endorsed directory '/home/hfluz/workspace/maven-test/web2/target/endorsed' is missing. You may need to a perform a Maven command line build in order to create it. pom.xml /web2 line 28 Maven Configuration Problem

Description Resource Path Location Type Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-dependency-plugin:2.1:copy (execution: default, phase: validate) pom.xml /web2 line 53 Maven Project Build Lifecycle Mapping Problem

There is already an /target/endorsed/javaee-endorsed-api-6.0.jar file.
IDE: JBoss Developer Studio 7 Beta 1 (tried with embedded 3.0.4 maven version and also with 3.0.5).
When I generate this same archetype through command line (maven 3.0.4) and import the project to eclipse, these errors are not displayed.
I just tried and the same happens with webapp-javaee6 archetype (also from org.codehaus.mojo.archetypes).

Anyone have any idea about what is causing this issue?

Solution

Try refreshing the target folder in eclipse (workspace seems out of sync).
