Well @insookwa i think this a version problem. Check the version of the package you want to install and check if maven has it’s equivalent. ---

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](https://maven.apache.org/guides/mini/guide-proxies.html). 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** 1. Go to `%USERPROFILE%\.m2\org\apache\maven\plugins\maven-resources-plugin\2.6` 2. Delete all the files there 3. Go [here](https://repo1.maven.org/maven2/org/apache/maven/plugins/maven-resources-plugin/2.6/) and download the following files: - maven-resources-plugin-2.6.jar - maven-resources-plugin-2.6.jar.sha1 - maven-resources-plugin-2.6.pom - maven-resources-plugin-2.6.pom.sha1 4. Move all those files into `%USERPROFILE%\.m2\org\apache\maven\plugins\maven-resources-plugin\2.6` 5. Reopen Eclipse ---

Thank you so much @ibacher though ive stumbled on a few new challenges 1. on downloading the maven-resources-plugin-2.6.jar.sha1, i got this:[dd093ff6a4b680eae7ae83b5ab04310249fc6590](https://repo1.maven.org/maven2/org/apache/maven/plugins/maven-resources-plugin/2.6/maven-resources-plugin-2.6.jar.sha1). 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 . 2. 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 ; Could not calculate build plan: Plugin org.apache.maven.plugins:maven-war-plugin:2.2 or one of its dependencies could not be resolved: Failure to transfer org.apache.maven.plugins:maven-war-plugin:jar:2.2 from [Central Repository:](https://repo.maven.apache.org/maven2) was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced.

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. ---

Or as @mozzy suggested, build from the command line and see if that works. ---

OK let me try that thanks @ibacher @mozzy @joachimjunior
