HttpBuilder上传文件没有扩展名

Question

所以我得到了这个gradle脚本，让我上传apx到Nexus。问题是这些文件最终没有服务器上的文件扩展名，如果你想从那里下载应用程序就会出现问题。

似乎我通过了正确的mime类型，但即便如此，我仍然会收到没有扩展名的文件。

以下是代码：

def uploadToRepository(File file, 
    String folder, 
    String url, 
    String userName, 
    String password){

    HTTPBuilder http = new HTTPBuilder(url)
    String basicAuthString = "Basic " + "${userName}:${password}".bytes.encodeBase64().toString()

    http.client.addRequestInterceptor(new HttpRequestInterceptor() {
        void process(HttpRequest httpRequest, HttpContext httpContext) {
            httpRequest.addHeader('Authorization', basicAuthString)
        }
    })
    try {
        http.request(Method.POST, "application/vnd.android.package-archive") { req ->
            uri.path = "/content/repositories/releases/${folder}"

            MultipartEntity entity = new MultipartEntity()
            def fileBody = new FileBody(file, "application/vnd.android.package-archive")
            entity.addPart("file", fileBody)
            req.entity = entity

            response.success = { resp, reader ->
                if(resp.status == 201) {
                    println "File ${file.name} uploaded"
                }
            }
        }

    } catch (Exception e) {
        e.printStackTrace()
    }
}
