Spring maven error

Question

I'm using spring MVC with maven to develop a web application, but when I update my dependencies I get this message:

5/6/10 10:09:50 AM CEST: Build errors for amundsen.web; org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:2.4.1:resources (default-resources) on project amundsen.web: Execution default-resources of goal org.apache.maven.plugins:maven-resources-plugin:2.4.1:resources failed: Plugin org.apache.maven.plugins:maven-resources-plugin:2.4.1 or one of its dependencies could not be resolved: Unable to get dependency information for org.apache.maven.plugins:maven-resources-plugin:maven-plugin:2.4.1: Failed to process POM for org.apache.maven.plugins:maven-resources-plugin:maven-plugin:2.4.1: Non-resolvable parent POM org.apache:apache:6 for org.apache.maven:maven-parent:13: Failed to resolve POM for org.apache:apache:6 due to The repository system is offline and the requested artifact is not locally available at /home/waleed/.m2/repository/org/apache/apache/6/apache-6.pom

Any idea?

Answer 1

The build is not failing because of one of your dependencies, it's failing because of one of the dependencies of the maven-resources-plugin. More precisely, Maven is not able to resolve org.apache:apache:pom:6 which is available in central though:

http://repo1.maven.org/maven2/org/apache/apache/6/apache-6.pom

Are you using m2eclipse? Is it configured to run offline (as the trace seems to suggest)? Or could this be related to MNGECLIPSE-1802?

Try to run maven on the command line, it should work and allow to workaround the issue with m2eclipse.

Answer 2

Maven is not able to resolve org.apache:apache:pom:6 as it's working offline. When working in offline mode, the dependencies not already in the local repository will be inaccessible.

Try to run maven from command prompt and examine the current configurations
