Erro ao tentar chamar a classe produtos

Oi Flavia,

Posta o seu pom.xml e as classes ContatoServlet.java e Produto.java por favor

Oi! Eu refiz umas vezes... mas continua com erro. Seguem as classes e o pom: pom.xml:

ContatoServlet

package br.com.alura.maven.lojaweb;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import br.com.alura.maven.Produto;

@WebServlet(urlPatterns = { "/contato" })
public class ContatoServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        //Produto c = new Produto("TESTE PROD", 1.0); 
        PrintWriter writer = resp.getWriter();
        writer.println("<html><h2> Entre em Contato </h2></html>");
        writer.close();
    }

}

Produto

package br.com.alura.maven;

public class Produto {
    private final String nome;
    private final double preco;


    public String getNome() {
        return nome;
    }

    public double getPreco() {
        return preco;
    }

    public Produto(String nome, double preco) {
        super();
        this.nome = nome;
        this.preco = preco;
    }

    public double getPrecoComImposto() {
        // TODO Auto-generated method stub
        return preco * 1.1;
    }

}

Deixei a chamada da classe Produto comentada... se eu descomento, ele pára de funcionar. Entretanto, a importação da classe não dá problema. Só ao instanciar mesmo.

Erro: HTTP ERROR 500 Problem accessing /contato. Reason:

Server Error

Caused by: java.lang.Error: Unresolved compilation problems: Produto cannot be resolved to a type Produto cannot be resolved to a type
