ant jsch.jar - 一個錯誤及解決辦法

　　運行build.xml出現異常：

　　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.

　　解決方法: 加入jsch-x.x.x.jar

　　Go to Window > Preferences > Ant > Runtime > Classpath, select 「Ant Home Entries (default)」 and click 「Add External JARs…」. Select the required dependency or dependencies and accept. Now, the selected JAR files will be loaded to the class path and the optional ant task depending on them will work.
