JacksonParser数据绑定和核心原因和QUOT;找到重复文件APK＆QUOT;？ [英] JacksonParser databind and core cause "Found duplicate file for APK"?

问题描述

我想学习如何使用杰克逊解析器，以获得更有效的分析对JSON数据。我有这些jar文件： 下载此页面

I'm trying to learn how to use jackson parser, to get more effective parsing on json data. I have these jar files: Downloaded from this page

 jackson-core-2.2.0.jar
 jackson-annotations-2.2.0.jar
 jackson-databind-2.2.0.jar

而在code，我只是尝试解析JSON到一个对象数组：

And in code, i just try to parse a json into an objects array:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    String json = ReadFromRaw(this, R.raw.json);
    ArrayList<Category> categories = null;
    try {
        ObjectMapper mapper = new ObjectMapper(); 
        categories = mapper.readValue(json, mapper.getTypeFactory().constructCollectionType(List.class, Category.class));
        // categories = mapper.readValue(json, new TypeReference<List<Category>>() {});
    } catch (Exception e) {
        Log.e("MainActivity", "Error: " + e.getMessage());
    }

    SimpleListView myList = (SimpleListView) findViewById(R.id.myList);
    myList.setAdapterWithItems(GetAdapter(categories));
} 

不知道是否有必要，但这里是我的范畴类，以及：

Not sure if necessary, but here is my Category class as well:

@JsonIgnoreProperties({ "DisplayPriority" })
public class Category {

    @JsonProperty("Id")
    private String categoryId;

    @JsonProperty("name")
    private String categoryName;

    public String getCategoryId() {
        return categoryId;
    }

    public void setCategoryId(String categoryId) {
        this.categoryId = categoryId;
    }

    public String getCategoryName() {
        return categoryName;
    }

    public void setCategoryName(String categoryName) {
        this.categoryName = categoryName;
    }

}

一切似乎都正常，没有错误或警告。但是，当我尝试编译，它给这个错误：

Everything seems ok, there is no error or warnings. But when i try to compile, it gives this error:

[2013-04-25 09:32:08 - Training - JacksonParser] Error generating final archive: Found duplicate file for APK: LICENSE
Origin 1: C:\~\workspace\Training - JacksonParser\libs\jackson-core-2.2.0.jar
Origin 2: C:\~\workspace\Training - JacksonParser\libs\jackson-databind-2.2.0.jar

正如我搜索在谷歌这个错误，它说有一些类常见的这些jar文件。而且我没有做什么，所以任何想法？有什么我做错了什么？否则我缺什么吗？

As i search for this error on google, it says there is some class in common on these jar files. And i do not have any idea about what to do so... Is there something that i do wrong? Or i do something missing?

由于提前，任何帮助是AP preciated。

Thanks in advance, any help is appreciated.

推荐答案

我有同样的问题。 所以，我用的是旧版本。

I have the same problem. So, I use the old version.

杰克逊核心ASL-1.9.12.jar

jackson-core-asl-1.9.12.jar

杰克逊映射器-ASL-1.9.12.jar

jackson-mapper-asl-1.9.12.jar

您可以从最新稳定版本1.x中在同一页面中下载。

You can download from "Latest stable 1.x version" of the same page.
