>PROBLEM
Maven fails to load spring references

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6
Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6

Failure to transfer org.apache.maven.plugins:maven-resources-plugin:pom:2.6 from http://maven.repository.redhat.com/ga/ was cached in the local repository, resolution will not be reattempted until the update 
 interval of redhat-ga-repository has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.6 from/to redhat-ga-repository (http://
 maven.repository.redhat.com/ga/): maven.repository.redhat.com

>SOLUTION
Check the repository location into ".m2\settings.xml".

For instance:
C:\Users\YourLogin\.m2\settings.xml

In this case the localRepository was configured with linux's location and not windows as it was supposed to be:

***WRONG:
/home/portables_d/mvnlibs

+++RIGHT:
${env.LOCAL}\portables_d\mvnlibs



>ENV
windows
eclipse
