异常java.lang.NoSuchMethodError：org.apache.wicket.AttributeModifier.append（Ljava /朗/字符串; Ljava / IO /序列化;） [英] Exception java.lang.NoSuchMethodError: org.apache.wicket.AttributeModifier.append(Ljava/lang/String;Ljava/io/Serializable;)

问题描述

我试图用一个ObjectAutoCompleteBuilder以如下打造ObjectAutoCompleteField：

I tried to use an ObjectAutoCompleteBuilder to build ObjectAutoCompleteField as below:

ObjectAutoCompleteBuilder builder = new ObjectAutoCompleteBuilder(provider);
    builder.autoCompleteRenderer(renderer);

    final ObjectAutoCompleteField autocompleteField = builder.build("searchResource" , new Model());
    final TextField searchResource = autocompleteField.getSearchTextField();
    searchResource.setRequired(true);

但它抛出这个异常：

but it has thrown this exception :

java.lang.NoSuchMethodError: org.apache.wicket.AttributeModifier.append(Ljava/lang/String;Ljava/io/Serializable;)Lorg/apache/wicket/behavior/AttributeAppender;

有没有人有任何想法，为什么？

Does anyone have any idea why?

推荐答案

您正在使用检票的错误版本（1.4.17）为您正在使用的WicketStuff项目（1.5.4）。

You're using the wrong version of Wicket (1.4.17) for the WicketStuff project you're using (1.5.4).

从 WicketStuff维基：

我们的释放过程让最终用户一个简单的方法来跟踪相对检票发布周期的项目。

Our release process allows end users an easy way to track a project relative to the wicket release cycle.

例如，如果用户看到一个org.wicketstuff：someproject工件与版本1.4.16.1他们可以立即知道它是基于便门1.4.16，并且它是第一点释放（在1.4.16版本将是原始版本）。

For example, if a user sees a org.wicketstuff:someproject artifact with a version of 1.4.16.1 they can know immediately that it is based on wicket 1.4.16 and that it is the first point release (the 1.4.16 version would have been the original release).

所以，你需要的Wicket 1.5 - 或者找到基于1.4.17版本的自动完成

So you need Wicket 1.5 - or find a version of autocomplete based on 1.4.17.
