when i open openmrs-web and other maven projects in eclipse i get this error :
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
Does anyone know how to go about it .thanks
@mozzy
Given that the maven-resources-plugin is a core component, this sounds like the likely cause is either a corrupted or missing file. First, if you’re behind a proxy, you’ll need to configure Maven to work with your proxy. Second, there are two possible approaches to resolving the issue: the easy way, which requires a good internet connection, and the slightly more complex way that can probably be done with any internet connection.
The Easy Way
Delete the %USERPROFILE%\.m2 directory (I think this is usually where it is but I’m not 100% certain on Windows). Reopen Eclipse and try to build the project.
Slightly more complex way
Go to %USERPROFILE%\.m2\org\apache\maven\plugins\maven-resources-plugin\2.6
Thank you so much @ibacher though ive stumbled on a few new challenges
on downloading the maven-resources-plugin-2.6.jar.sha1, i got this:dd093ff6a4b680eae7ae83b5ab04310249fc6590. its the same withmaven-resources-plugin-2.6.pom.sha1. i am new to maven and would request to know how am i supposed to add it to the repositories .
after deleting the former files and adding the new downloaded files “maven-resources-plugin-2.6.jar”. ive re opened eclipse and tried to build another maven project and i recived these errors ;

Thanks @ibacher for digging deep into this. I like that
However what i can say , Ecllipse maven plugin is always trouble some.
First try to follow the steps @ibacher has outlined ,
another option , would be ,
If you have maven installed on your machine ,
Just ensure you can build your project successfully without any errors in your command line and if that happens , then you may ignore eclipse maven plugin errors.
I always forget that the Eclipse Maven Plugin tries to do it’s own thing… as if Maven wasn’t complex enough already!
At this point you might want to consider clearing out the .m2 directory completely. Or as @mozzy suggested, build from the command line and see if that works.
