錯誤：包org.jboss.netty.channel.socket.nio不存在

Question

哪個JAR包含org.jboss.netty.channel.socket.nio？我是而不是使用maven或常春藤，只是螞蟻（從netbeans）。

螞蟻編譯給出：

-do-compile: 
    [javac] Compiling 4 source files to /home/thufir/NetBeansProjects/EchoClient/build/classes 
    [javac] /home/thufir/NetBeansProjects/EchoClient/src/net/bounceme/dur/netty/client/ObjectEchoClient.java:3: error: package org.jboss.netty.channel.socket.nio does not exist 
    [javac] import org.jboss.netty.channel.socket.nio.NioClientSocketChannelFactory; 

在類路徑是：

這是一個從下載：

http://netty.io/downloads.html

網狀，4.0.21.Final.tar .bz2

我將該下載的每個JAR添加到項目中。是的，我意識到它沒有使用CLI javac classpath，但JAR在項目中以及在上面的輸出中都是可見的。

我翻看了一些JAR文件，無法找到這個特定的類。

您似乎在嘗試使用netty 4.0構建針對netty 3.x開發的應用程序。已有API changes，包括頻道創建和引導。此外，軟件包前綴已從org.jboss.netty更改爲反映項目狀態更改的io.netty。

使用API documentation（不再記錄NioClientSocketChannelFactory）與您正在使用的版本相對應，並檢出提供的示例（netty-example-4.0.21.Final-sources.jar）以幫助移植您擁有的任何代碼針對netty 3.x構建。
