Is there anything wrong I did?

If the downloading was interrupted, some files may be corrupted or incomplete, and currently Maven is not smart enough to re-download those files, so you just need to delete the cached dependencies and force Maven to re-download: 1. Make sure you have a reliable internet connection. 2. Delete the `${USER}/.m2` folder. 3. Right click on the project and select Maven -> Update Project 4. Wait until all background operations are finished. In Eclipse you can see the background operations in the Progress view.

Also I noticed that when I added the dependency of org.springframework:spring-webmvc, I start to get these errrors on pom.xml Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5 Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5 Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5 Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5 Attachments: error1.jpg error2.jpg Last edited by agedam at 13:24 Apr 12, 2013.

Also check the .m2 folder and see if the resources plugin was downloaded correctly. It should be under the folder ${USER}\.m2\repository\org\apache\maven\plugins\maven-resources-plugin\2.5. Check if you have both the .jar file and .pom file. The .jar file should be about 26KB and the .pom file should be about 7KB.

You should have a file with the .pom suffix but you don't, which means the previous download failed. Just delete the folder (i.e. 2.5/) and do a Maven update project again in Eclipse to force Maven to re-download the plugin.

I am getting the same errors when I add the spring dependency Project build error: 'dependencies.dependency.version' for org.springframework:spring-webmvc:jar is missing. Also in the pom file the error I'm getting is null (org.apache.maven.plugins:maven-war-plugin:2.1.1:war:default-war:package) null (org.apache.maven.plugins:maven-resources-plugin:2.5:testResources:default-testResources:process-test-resources) null (org.apache.maven.plugins:maven-resources-plugin:2.5:resources:default-resources:process-resources)

You need to specify a version for the dependency. In the guide I didn't say which version because I want you to use the latest version. So for example, if it asks you to add a dependency "org.springframework:spring-webmvc", it means you should add the latest version of the dependency whose artifact id is spring-mvc and group id is org.springframework. You can easily find the dependencies if you use the GUI in Eclipse.
jrodriguez Posts: 33	Posted 14:42 Apr 16, 2013 \| When I use the GUI on eclipse it does not give me any results for spring-webmvc. Am I missing something else? I have all the plugins installed.
jrodriguez Posts: 33	Posted 14:45 Apr 16, 2013 \| I have it working already. It was 3.2.2.RELEASE for version
