Eclipse project can't find "org.joda"

Question

I'm using Eclipse Kepler, and Apache Maven 3.1.1. I just installed both and did so properly as far as I know.

I'm trying to install Joda Time from the Maven repository. I added the dependencies to the pom.xml, but my project can't resolve the joda libraries even with a maven clean install.

My repository is located at USER_FOLDER/.m2/repository/. The joda-time folder and its contents are present there after I navigate to my project folder in a prompt and run "mvn clean", then "mvn install".

I haven't changed any build paths or other project settings in my Eclipse project.

Eclipse Maven integration is installed.

I followed this tutorial found on the Spring website: http://spring.io/guides/gs/maven/

My file structure is as follows:

USER
|____ .m2
|    |____ repository
|         |____ joda-time [and other folders such as org]
|              |____ joda-time
|                   |____ 2.3
|                        |____ _remote.repositories
|                        |____ joda-time-2.3.jar
|                        |____ joda-time-2.3.jar.sha1
|                        |____ joda-time-2.3.pom
|                        |____ joda-time-2.3.pom.sha1
|____ workspace
|    |____ hello
|    |    |____ [project files]
|    |    |____ pom.xml
|    |    |____ dependency-reduced-pom.xml
|    |    |____ target
|    |         |____ [compiled files. Nothing related to Joda, though]
|    |____ .metadata [with .plugins folder and others]

Here is my pom.xml:

            </executions>

    </plugins>

</project>

Here is my HelloWorld.java main file. On the import line, I get the error message "The import org.joda cannot be resolved".

package main.java.hello;

import org.joda.time.LocalTime;

public class HelloWorld {
    public static void main(String[] args) {
        LocalTime currentTime = new LocalTime();
    }
}

Answer 1

mvn eclipse:eclipse

Is also required to generate project files which includes .classpath for eclipse.

Answer 2

Right click the project and click on Configure> Convert Project to Maven Project
