小弟不才，去年学习 flutter 的过程中，搞过几个小玩具，其中就有一个将 json 数据转换成 dart class 的 idea 插件。
gayhub 传送门
不想点的朋友可以看一下 gif
半年多来，随着 flutter 的火热，github 上也有了那么几十个 star。后来我也发布到了全家桶插件官网。陆陆续续也有几千个的下载量了。对于我这个小透明来说，还是挺开心的，不管写得有多烂，总归是有人在用，总归是为 flutter 的生态贡献了自己的一点绵薄之力。
然而就在今天，当我想去看看那些下载量更高的同类项目的时候，很不凑巧的就让我发现了这么一个作品：
先上一张他的 gif 吧
敏感的我，一下子就感觉到了有点不对劲，于是我点开了他的源码开始查看，有如下收获：
1.ClassGenerator 类名一样的
2.NameValuePair/NamePair 极其相似，而且讲道理，NamePair 这个命名很不自然
3.Param 类名一样
4.Util/Utils 基本没差别
没耐心的朋友可以不用看代码，我以我的人格担保，最后的结论是没错的

是不是一个模子刻出来的？大量的函数名、属性名都是一致的，换行空行也都是一致的
由于我已经将 NameValuePair 用 kotlin 改写了，下面的代码是从 git 提交记录里找到的
/**
* Created by zhangll on 2018/8/3.
*/
public class NameValuePair {
String name;
String value;
public NameValuePair(String name, String value) {
this.name = name;
this.value = value;
}
}
public class NamePair {
private String camelKey;
private String key;
private String value;
public NamePair(String camelKey, String key, String value) {
this.camelKey = camelKey;
this.key = key;
this.value = value;
}
public String getCamelKey() {
return camelKey;
}
public void setCamelKey(String camelKey) {
this.camelKey = camelKey;
}
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
乍一看似乎不一样，其实他只是多写了 getter setter，又加了一个驼峰命名功能的字段。我怎么看出来一致的呢？因为 NameValuePair 严格来说，就应该给属性命名 name 和 value。而另一个人的类名叫 NamePair，中间偏偏少了个 Value ，属性命名却又是 key（不是理论上的 name）、value，这是为什么呢？明眼人应该一看就知道了。

public static void writeToFile(VirtualFile file, String content) {

}
所以，唯一的不同就是我类头有注释，而他多了一个驼峰命名的方法。
放上另一个人的项目地址，有闲心的朋友可以自己去看
github.com/xlyasdasd/F…
总结一下
如果就 copy 一下我的代码过去用，其实我肯定也没什么，按道理来说作为一个程序猿我还应该觉得开心才是。
但是 copy 了我整个项目，又极其不专业的只改了几个不痛不痒的地方，改得此地无银三百两，留着项目结构、类命名、方法命名、空行、换行这些个人风格浓重的东西不动，我是 Kotlin 写的地方他就是 Kotlin，我用 Java 写的地方他就是 Java， 难道是因为核心逻辑看不懂不敢改动吗？既然能自己加上驼峰命名的功能，想来也不至于。
如果只是 copy 项目也就罢了，他甚至还发布到了全家桶插件的官网，如果不是因为下载量比我自己的插件还高，恐怕这事我到死都不会知道。
当然，他没什么错，是我自己没给开源项目加上 LICENSE。但想来就算我有 LICENSE，按他能去发布插件这个勇气来看，只怕也是不在乎的。
有朋友跟我说，我应该开心，应该有成就感，因为至少这证明我做的东西是有价值的，但我觉得事情不应该这么去看待。我花了心思去写出来的东西，我心肝情愿的开源，我心肝情愿的给别人用，但是拿了我的心血去换个包装贴上他自己的牌子，这谁能接受？
作为一个喜欢 flutter 的开发者，我也不至于因为这事就丧了气，尽管也付出了不少时间，做了不少迭代，但毕竟只是一个小玩具项目而已。只是这次被好好的上了一课，以后不论多小的项目，LICENSE 是一定不能少的。
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持 我们
