Ant can't find my JAR file? Trying to do an sshexec task
提问by James
I'm trying to use the sshexec task for ANT on my OSX box, when I try to run it I get the error listed below. I've downloaded the jsch jar file from: http://www.jcraft.com/jsch/index.htmlversion jsch-0.1.43.jar
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版本 jsch-0.1.43.jar
I placed that file into /usr/share/ant/lib and still the error occurs. any ideas?
我将该文件放入 /usr/share/ant/lib 中，但仍然发生错误。有任何想法吗？
thanks
谢谢
<target name="testme" depends="">
<sshexec host="myhost1" username="${username}" command="ls -la" keyfile="${user.home}/.ssh/id_rsa" />
</target>
I get the following error:
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.
UPDATE:::: I installed a new version of ANT from apache and put it in /usr/local and moved the jsch file into /usr/local/ant/lib and it fixes the error, however now I have a new one when I run it with: ant -f deploy.xml restart
更新:::: 我从 apache 安装了一个新版本的 ANT 并将其放在 /usr/local 并将 jsch 文件移动到 /usr/local/ant/lib 并修复了错误，但是现在我有了一个新版本我运行它： ant -f deploy.xml restart

looks like a version compatibility issue, check the version of jsch matches the one supported by the ant version.
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。

Found the problem, when trying to fix the old ant version I had this file left over from my debugging attempts: /Library/Java/Extensions/jsch-0.1.8.jar
发现问题，当我尝试修复旧的 ant 版本时，我的调试尝试留下了这个文件：/Library/Java/Extensions/jsch-0.1.8.jar
I removed that guy and all is well

<sshexec trust="true"
