java - Ant 找不到我的JAR 文件？尝试执行 sshexec 任务

Question

我试图在我的 OSX 机器上使用 ANT 的 sshexec 任务，当我尝试运行它时，我得到下面列出的错误。我已经从以下位置下载了 jsch jar 文件:http://www.jcraft.com/jsch/index.html jsch-0.1.43.jar版本

我将该文件放入/usr/share/ant/lib 中，但仍然出现错误。有什么想法吗？

谢谢

<target name="testme" depends="">
 <sshexec host="myhost1" username="${username}" command="ls -la" keyfile="${user.home}/.ssh/id_rsa" />
</target>

我收到以下错误:

BUILD FAILED
/Users/jim/Code/myapp/deploy.xml:16: Problem: failed to create task or type sshexec
Cause: the class org.apache.tools.ant.taskdefs.optional.ssh.SSHExec was not found.
        This looks like one of Ant's optional components.
Action: Check that the appropriate optional JAR exists in
        -/usr/share/ant/lib
        -/Users/jim/.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.

更新::::我从 apache 安装了一个新版本的 ANT 并将其放入/usr/local 并将 jsch 文件移至/usr/local/ant/lib 并修复了错误，但是现在我运行它时有了一个新版本: ant -f deploy.xml 重启

看起来是版本兼容性问题，检查jsch的版本是否与ant版本支持的版本匹配。
