jpa类方法抛出的java.lang.NoSuchMethodError异常

Question

所以这里有三个类 ElConditionEntity ， AlertTemplateEntity 和 AlertEntitiesAssertions

AlertTemplateEntity与数据库中的表对应。 ElConditionEntity是AlertTemplateEntity类中的嵌入文件。

AlertEntitiesAssertions是一个辅助类，用于为测试用例类设置对象实例。

每当我在 Eclipse 中运行测试用例时，测试用例都可以毫无例外地传递。

但是，如果我在命令行中以build.xml 开始运行测试用例，则会出现由 setExpression方法引起的java.lang。 NoSuchMethodError 异常在ElConditionEntity 类中。此外，跟踪错误堆栈，上面的setExpression方法有一些我甚至没有在我的项目中定义的方法。那些错误堆栈没有行号。

由此引起的一系列失败的测试用例。

简化代码如下：

@Entity
@Table(name="alert_templates")
public class AlertTemplateEntity {

         @Column(name="type",nullable=false)
         @Basic(optional=false)
         private GgsObjectType objectType;

         @Basic(optional=false)
         private Severity severity;

         private ELConditionEntity condition;

         @OneToMany(cascade=CascadeType.ALL,mappedBy="alertTemplate")
         private List<AlertEntity> alerts = new ArrayList<AlertEntity>();

         @Basic(optional=false)
         @Column(name="suppression_time")
         private int suppressionTime;

         @Column(name="message_template", length=4000)
         private String messageTemplate;

         ..................
} 

 @Embeddable
 public class ELConditionEntity  {

   @Basic(optional=false)
   @Column(length=4000)
   private String expression;

   @Column(name="expression_template",length=4000)
   private String template;

   public String getExpression() {
     return expression;
   }

   public String getStringTemplate() {
     return template;
   }

   public void setExpression(String expression) {
     this.expression = expression;
   }
   ...........

 }

public class AlertEntitiesAssertions{

     public static final String EL_EXPRESSION = "${value==111}";
     public static final String EL_STRING_TEMPLATE = "${value} == 111";

    public static AlertTemplateEntity newTemplate(boolean withSubscription) {

        final AlertTemplateEntity template = new AlertTemplateEntity();
        template.setObjectType(TYPE);
        template.setName(NAME);
        template.setSeverity(SEVERITY);
        template.setSuppressionTime(SUPPRESSION_TIME);
        final ELConditionEntity condition = newCondition();
        template.setCondition(condition);
        ..........................
      }


   public static ELConditionEntity newCondition() {

         final ELConditionEntity condition = new ELConditionEntity();
         condition.setExpression(EL_EXPRESSION);
         condition.setStringTemplate(EL_STRING_TEMPLATE);
         return condition;
      }

    }

错误堆栈：
