Falha ao inserir dados no banco com o Hibernate

Programação Java
#1

Boa tarde pessoal, estou passando por um problema ao fazer a inserção na minha base de dados usando Hibernate. Ao executar o arquivo teste de inserção eu estou recebendo o seguinte erro:

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (default-cli) on project your-artifactid: Command execution failed. Process exited with an error: 1 (Exit value: 1) -> [Help 1]

Faz um bom tempo que estou tentando resolver, porém ainda não consegui. Vou continuar tentando, porém resolvi pedir ajuda a vocês. Se tiverem um tempinho o meu código está aqui: https://github.com/CristianoNicolaFerreira/Web-Agil-Com-VRaptor-Hibernate-e-Ajax.git

Olá,

Veja o seu pom.xml :

<dependency>
        <groupId>unknown.binary</groupId>
        <artifactId>hibernate-jpa-2.1-api-1.0.0.Final</artifactId>
        <version>SNAPSHOT</version>
</dependency>

Bom dia pessoal, estou com o mesmo problema á algumas semana já, foi solucionado?
Estou criando um sistema web no Netbeans utilizando o Maven. Ao executar a classe principal apresenta esse erro:

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (default-cli) on project AcademiaKf: Command execution failed. Process exited with an error: 1 (Exit value: 1) -> [Help 1]
