Jersey RESTful web service gradle setup
提问by ruabmbua
I am stuck with creating a gradle project for a RESTful web service using the jersey library. The project configuration should be capable of launching the service inside a jetty application server. I already found a resource: https://github.com/ziroby/jetty-gradle-hello-world
我坚持使用 jersey 库为 RESTful Web 服务创建一个 gradle 项目。项目配置应该能够在 jetty 应用服务器内启动服务。我已经找到了一个资源：https: //github.com/ziroby/jetty-gradle-hello-world
My problem with that solution is, that it uses an outdated version of jersey. I need at least version 2(preferred latest 2.14). I tried to search for new versions on maven central, but in version 2 a lot of artifact names changed, and I am not able to configure it correctly.
我对该解决方案的问题是，它使用了过时的球衣版本。我至少需要版本 2（最好是最新的 2.14）。我试图在 maven central 上搜索新版本，但在版本 2 中，很多工件名称发生了变化，我无法正确配置它。
Edit: I do not specifically need a jetty server in my project. It can be any application server, which is suitable for testing and debugging my app. I am using jetty also in production, so it would be nice to use jetty.
编辑：我的项目中并不特别需要码头服务器。它可以是任何适用于测试和调试我的应用程序的应用程序服务器。我也在生产中使用码头，所以使用码头会很好。

第一的
Get rid of all the Jersey dependencies you currently have
摆脱您目前拥有的所有 Jersey 依赖项
dependencies {
testCompile 'junit:junit:4.11'
testCompile 'org.hamcrest:hamcrest-all:1.3'
+------------- ======= JUNK ======= ----------------+
| testCompile 'com.sun.jersey:jersey-client:1.17.1' |
| compile 'com.sun.jersey:jersey-core:1.17.1' |
| compile 'com.sun.jersey:jersey-server:1.17.1' |
| compile 'com.sun.jersey:jersey-servlet:1.17.1' |
