Java、maven、hibernate - 映射问题

Question

我尝试了一个多小时来查找错误，但仍然找不到:

     cd C:\Users\zimnyk\Documents\NetBeansProjects\kwestionariusz; "JAVA_HOME=C:\\Program Files\\Java\\jdk1.8.0_40" cmd /c "\"\"C:\\Program Files\\NetBeans 8.0.2\\java\\maven\\bin\\mvn.bat\" -Dexec.args=\"-classpath %classpath com.mycompany.kwestionariusz.main\" -Dexec.executable=\"C:\\Program Files\\Java\\jdk1.8.0_40\\bin\\java.exe\" -Dmaven.ext.class.path=\"C:\\Program Files\\NetBeans 8.0.2\\java\\maven-nblib\\netbeans-eventspy.jar\" -Dfile.encoding=UTF-8 org.codehaus.mojo:exec-maven-plugin:1.2.1:exec\""
    Running NetBeans Compile On Save execution. Phase execution is skipped and output directories of dependency projects (with Compile on Save turned on) will be used instead of their jar artifacts.

这就是错误的样子，我的映射文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
  <class name="com.mycompany.kwestionariusz.Osoba" table="DaneOsobowe">
        <property name="imie" column="Imie"/>
        <property name="nazwisko" column="Nazwisko"/>
        <property name="telefon" column="Telefon"/>
        <property name="email" column="Email"/>
        <property name="uczelnia" column="Uczelnia"/>
        <property name="doswiadczenie" column="Doswiadczenie"/>
        <property name="zainteresowania" column="Zainteresowania"/>
        <property name="skadSlyszal" column="SkadSlyszal"/>
  </class>
</hibernate-mapping>

这是我的配置文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
    <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
    <property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
    <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/postgres</property>
<property name="hibernate.connection.username">postgres</property>
<property name="hibernate.connection.password">test</property>
<mapping resource="Osoba.hbm.xml"/>


 </session-factory>
</hibernate-configuration>

这是我第一次使用 maven 和 hibernate，所以这个错误对我来说看起来很糟糕，你能帮我吗？

主文件第20行是:

Session session = NewHibernateUtil.getSessionFactory().getCurrentSession();
        session.beginTransaction();

NewJavaUtil 的第 ~31 行是:

}
     catch (Throwable ex) {
                // Log the exception. 
                System.err.println("Initial SessionFactory creation failed." + ex);
                throw new ExceptionInInitializerError(ex);
            }

问题出在新行中，当我在映射文件中的所有内容之间添加新行时，它就开始工作
