Maven build shows compilation error but Eclipse doesn't

I am facing a strange issue with Maven, looking for some help. My maven pom looks like this:

<dependency>
   <groupId>org.eclipse.californium</groupId>
   <artifactId>californium-core</artifactId>
   <version>1.0.0-SNAPSHOT</version>
   <scope>test</scope>
</dependency>

And added repository like this:

<repositories>
    <repository>
        <id>repo.eclipse.org</id>
        <name>Californium Repository</name>
        <url>https://repo.eclipse.org/content/repositories/californium/</url>
    </repository>
</repositories>

And Java class looks like this:

import org.eclipse.californium.core.CoapResource;
import org.eclipse.californium.core.CoapServer;
import org.eclipse.californium.core.server.resources.CoapExchange;

public class Hello extends CoapServer {
   //Code here
}

Problem is Eclipse doesn't throw any error, but when I try to run maven build from eclipse, I keep on getting many compilation errors like this:

[ERROR] D:\Pradeep\Workspaces\coap\CoapServer\src\main\java\com\pradeep\coap\server\CoapServer\CoapProxyServer.java:[3,35] error: package org.eclipse.californium.core does not exist

I verified if dependencies downloaded correctly by removing dependency tag, then even eclipse throws error, so I assume it means dependencies are downloaded correctly (I also see the jar files in Maven dependencies in eclipse). I am facing this issue while running build. Can anyone please guide me in this?

Your Hello class is in your source folder whereas you defined the dependency in scope test. Either move your class to src/test/java our change your dependency not to be a test dependency.

Eclipse cannot distinguish between the scopes and puts everything on the classpath for the whole module, regardless of the defined scope.
