java.lang.NoClassDefFoundError: org/glassfish/jersey/server/spi/Container - maven

Question

I am trying to set up a Jersey 2 servlet application. The goal is to map only some URLs to a Jersey REST API while other URLs serve static content.
I use mvn compile war:war to generate a war and deploy it. When deploying the artifact the following error occurs:
[2016-01-09 02:50:21,617] Artifact Test.war: Artifact is being deployed, please wait...
2016-01-09 14:50:25.823:WARN:oejd.DeploymentManager:Scanner-1: Unable to reach node goal: started

import javax.ws.rs.ApplicationPath;
#ApplicationPath("/api")
public class ApiApplication extends ResourceConfig {
public ApiApplication() {
packages(true, "group.id");
}
}
The test resource Test.java:

import javax.ws.rs.GET;
import javax.ws.rs.Path;
#Path("/test")
public class Test {
#GET
public String get() {
return "Hello world!";
}
}
When I look into the WAR-file the WEB-INF/lib is filled with JAR-files. Why can't Jetty deploy the WAR-file?

Answer 1

These three dependencies
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet</artifactId>
<version>2.22.1</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-server</artifactId>
<version>2.22.1</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.22.1</version>
<scope>provided</scope>
</dependency>
are already pulled in by this dependency
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-jetty-servlet</artifactId>
<version>2.22.1</version>
</dependency>
But when you declare them, you override the fact that it pulls them in. And you are declaring them as provided
<scope>provided</scope>
which means that you are saying the server has those dependencies, which it doesn't. If you look in the WEB-INF/lib, you will see that those three are not there. That's the reason for the error. The best thing to do is just get rid of those three, since they are already pulled in.
You can actually get rid of everything except that last one, as it pulls in everything you declared.
