How to use xstream fro xml serialization in eclipse
提问by Daniel
I am having some trouble figuring out how to download and use xstream in eclipse. When I download the binary distribution from the website, I get a zip file. Where should I extract it, and how do I use it?
我在弄清楚如何在 eclipse 中下载和使用 xstream 时遇到了一些麻烦。当我从网站下载二进制发行版时，我得到了一个 zip 文件。我应该在哪里提取它，以及如何使用它？

OK, I have added it to my build path, but now when I try to use XStream to serialize an ArrayList<Earmark>where Earmarkis a class that I have defined, I get the following error message:
好的，我已经将它添加到我的构建路径中，但是现在当我尝试使用 XStream 来序列化我定义的ArrayList<Earmark>whereEarmark是一个类时，我收到以下错误消息：
Exception in thread "main" java.lang.NoClassDefFoundError: org/xmlpull/v1/XmlPullParserException
at com.thoughtworks.xstream.XStream.<init>(XStream.java:334)
at examples.TestEarmarkExtractor.SerializeEarmarks(TestEarmarkExtractor.java:19)

... 3 more
Update: The error is occurring beforeI try the serialization. It occurs on the line
更新：在我尝试序列化之前发生错误。它发生在线路上
XStream xs = new XStream();

- Extract the zip file to a directory (e.g.
C:\Program Files\XStream) - In eclipse, right-click on your project and select
Build Path > Configure Build Path... - Select
Librariestab - Select
Add External Jars.. - Navigate to the
libfolder of your XStream download and select the jar(s) to be added - Select
Open - Select
OK
- 将 zip 文件解压缩到一个目录（例如
C:\Program Files\XStream） - 在 Eclipse 中，右键单击您的项目并选择
Build Path > Configure Build Path... - 选择
Libraries标签 - 选择
Add External Jars.. - 导航到
libXStream 下载的文件夹并选择要添加的 jar - 选择
Open - 选择
OK

Got this exception, then I download kxml2-min-2.3.0.jar and add it as a library and now it works (using xstream 1.4.4.jar)
得到这个异常，然后我下载 kxml2-min-2.3.0.jar 并将其添加为库，现在它可以工作（使用 xstream 1.4.4.jar）

You can add this library:
你可以添加这个库：
<dependency>
<groupId>xmlpull</groupId>
<artifactId>xmlpull</artifactId>
<version>1.1.3.1</version>
</dependency>

You need to unzip the .zip file to get at the .jar file, which you put on your classpath for your project in eclipse (Google if you don't know how to add third party library .jars to your project classpath in Eclipse).
您需要解压缩 .zip 文件以获取 .jar 文件，您将其放在 eclipse 中项目的类路径中（如果您不知道如何将第三方库 .jars 添加到 Eclipse 中的项目类路径，请使用谷歌） .
Once it is added to your project's classpath, you use the classes contained within it as you would any other classes, and the documentation on the XStream website tells you how to use them.
一旦将其添加到项目的类路径中，您就可以像使用任何其他类一样使用其中包含的类，并且 XStream 网站上的文档会告诉您如何使用它们。
Good choice by the way, XStream is great!
顺便说一句不错的选择，XStream很棒！

I had added the two libraries: dom4j-2.0.0-ALPHA-2.jarand xstream-1.4.7.jarand the same issue were displayed. After adding the kxml2-min-2.3.0.jarthe issue is not happening.
我添加了两个库：dom4j-2.0.0-ALPHA-2.jar并且xstream-1.4.7.jar显示了相同的问题。添加后kxml2-min-2.3.0.jar问题没有发生。
