每当我在eclipse中部署liferayportlet的war文件时，我都会遇到以下错误。有人能帮我知道为什么会发生这种情况以及如何解决它吗。

java.lang.LinkageError: loader constraint violation: when resolving overridden method "com.liferay.portal.spring.extender.internal.context.ModuleBeanFactoryPostProcessor.postProcessBeanFactory(Lorg/springframework/beans/factory/config/ConfigurableListableBeanFactory;)V" the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) of the current class, com/liferay/portal/spring/extender/internal/context/ModuleBeanFactoryPostProcessor, and its superclass loader (instance of org/apache/catalina/loader/WebappClassLoader), have different Class objects for the type org/springframework/beans/factory/config/ConfigurableListableBeanFactory used in the signature

java.lang.linkageerror发生在使用依赖版本（如v1）编译代码，然后使用依赖版本（如v2）运行代码时。
示例说明：编译时使用的是v1的父类（假设它来自liferay）

class Parent {
    public void method(String s) {
        s = "Hello " + s;
        System.out.println(s);
    }
}

// this is your project class
class Child extends Parent {
    @Overridden
    public void method(String s) {
        super.method(s);
        System.out.println("Hello from child : " + s);
    } 
}

因此，在构建项目jar时可以很好地进行编译。
但是，在运行时，您使用的是版本v2的父类，其方法定义如下 public void method(String s, int i) . 因此，它无法将您的类链接到父类，因此出现错误。
这里是包含类的库的运行时版本和编译时版本 com.liferay.portal.spring.extender.internal.context.ModuleBeanFactoryPostProcessor 它们是不同的。保持两个版本与编译时相同，一切都会很好。
