我試圖下載Netty Source Code並運行包含的示例。如何使Netty示例工作
我安裝的jdk版本是1.8.0_65。
我試圖將示例（在示例文件夾...\netty-4.1\example）轉換爲eclipse項目與maven（mvn eclipse:eclipse）。
但得到構建錯誤下面說。

而且我遵循了消息中提到的線索。我發現this solution哪個鏈接到http://netty.io/wiki/forked-tomcat-native.html#wiki-h3-6。
我認爲這可能不是我的目的（我只是想運行這些例子）。
所以我想知道任何Netty開發庫被下載到獲取啓動Netty應用程序開發。或者任何Pom.xml共享鏈接可以很容易地包含在示例項目中？謝謝。
你是否試過[Force maven update]中的指示（https://stackoverflow.com/questions/4701532/force-maven -Update？RQ = 1）？它有助於緩存在本地存儲庫中，直到中央的更新時間間隔或更新被強制解決爲止，分辨率纔會被重新嘗試。 – Ferrybig
是的。我已經嘗試過'mvn clean install -U'。錯誤仍然存在。 –
我很困惑，它試圖下載「io.netty：netty-tcnative：jar：windows-x86 _ ** 32 **：1.1.33.Fork11」。你的設置像32位maven或類似的東西的任何奇怪的事情？ – Ferrybig
