Ant运行build.xml执行服务器scp，异常解决jsch.jar

公司ant打包上线 一直出现这个问题。

Ant运行build.xml执行服务器scp，异常解决jsch.jar

BUILD FAILED
D:\eclipse\eclipse-jee-luna-SR2-win32-x86_64\hexindev\eservice\build.xml:95: Problem: failed to create task or type scp
Cause: Could not load a dependent class com/jcraft/jsch/Logger
It is not enough to have Ant's optional JARs
you need the JAR files that the optional tasks depend upon.
Ant's optional task dependencies are listed in the manual.
Action: Determine what extra JAR files are needed, and place them in one of:
-D:\eclipse\eclipse-jee-luna-SR2-win32-x86_64\eclipse\plugins\org.apache.ant_1.9.2.v201404171502\lib
-C:\Users\123456\.ant\lib
-a directory added on the command line with the -lib argument

Do not panic, this is a common problem.
The commonest cause is a missing JAR.

This is not a bug; it is a configuration problem

解决方法: 加入jsch-x.x.x.jar ，网上可以下载

打开 Eclipse->window->preferences->ant->runtime->classpath
select “Ant Home Entries (default)” and click “Add External JAR

选择下载好的jsch.jar

click Apply->OK
