Error generating code from an entity by extending Pojotype

In the project a Pojo class was created that receives the type of the serializable variable for indexing and treats the generic conversion:

Pojo.java:
    {...}
    public abstract class Pojo<T extends Serializable> implements Serializable {
      private static final long serialVersionUID = -519803732136444707L;
      public abstract T getId();          
      public abstract void setId(T id);
    }

When creating a class in the package domain and extending it, the declaration line looks like this:

Empresa.java:
    {...}
    public class Empresa extends Pojo<Long> implements Serializable{
    {...}

Then the nimble is run for the crud generation of it, I'm using a custom template, based on JSF2 (primefaces 3) CRUD.   When manipulating the class for code generation, groovy displays the following error:

        java.io.FileNotFoundException: C:[...]\src\main\java\br\com\djsystem\

The same error occurs when I use in my entity a composite attribute whose class also extends the Pojo, under ManyToMany, ManyToOne, etc.  In this second case the error occurs in the generation of the select / picklist.  I also checked that it only occurs when using groovy commands, since .vm files are generated normally.

Can anyone who has ever had this problem help me find a solution?

Standard class

    @Entity
    @Table(name = "Cliente", uniqueConstraints = {
        @UniqueConstraint(columnNames = {"cnpj"})})
    public class Cliente extends Pojo<Long> implements Serializable {

        private static final long serialVersionUID = 1654193767247607000L;

        @Id
        @Column(name = "id", columnDefinition = "serial")
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        private Long id;

        @Column(name = "razao_social", nullable = false, length = 80)
        private String razaoSocial;

        @Column(name = "cnpj", nullable = false, length = 14)
        private Long cnpj;

        @Column(name = "fantasia", nullable = false, length = 60)
        private String fantasia;

        public Cliente() {
            super();
        }

        public Long getId() {
            return id;
        }

        public void setId(Long id) {
            this.id = id;
        }

        public String getRazaoSocial() {
            return razaoSocial;
        }

        public void setRazaoSocial(String razaoSocial) {
            this.razaoSocial = razaoSocial;
        }

        public Long getCnpj() {
            return cnpj;
        }

        public void setCnpj(Long cnpj) {
            this.cnpj = cnpj;
        }

        public String getFantasia() {
            return fantasia;
        }

        public void setFantasia(String fantasia) {
            this.fantasia = fantasia;
        }

    }
