基本上是仿照sdk中的例子做的， Walkthrough: Add a Custom Button to an Existing Group for a Specific Entity） 如果下面描述的不清楚，请联系我，我会尽量详细反映问题的。因为好像不能截图。
下面是我在导出的customizations.xml 中自己添加的代码：new_skillcategories是自定义实体，导入时报的错误是：名称：new_js_sendToOther.js 详细信息： 发生了错误，请重试此操作。
我的资源文件的分别名称为：new_js_sendToOtherjs1C83C81A-7BB7-DF11-840E-00155DBA380F ，SycnIcon16x16pngD5D2EC98-666A-E011-B3F3-00155D011934，SycnIcon32x32pngD5D2EC98-666A-E011-B3F3-00155D011933 。这些id都是我自己写的，不知道是什么作用。
