Question

我正在尝试在我的OSX盒子上使用sshexec任务进行ANT，当我尝试运行它时，我得到下面列出的错误。我从以下版本下载了jsch jar文件：http://www.jcraft.com/jsch/index.html版本jsch-0.1.43.jar

我将该文件放入/ usr / share / ant / lib中，但仍然发生错误。任何想法？

感谢

<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.

UPDATE :::: 我从apache安装了一个新版本的ANT并将它放在/ usr / local中并将jsch文件移动到/ usr / local / ant / lib中它修复了错误，但是现在我运行它时有一个新的： ant -f deploy.xml restart

Answer 1

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

也许

Answer 2

发现问题，当我尝试修复旧的ant版本时，我的调试尝试遗留了这个文件： /Library/Java/Extensions/jsch-0.1.8.jar

我删除了那个人，一切都很好

Answer 3

下载jsch-0.1.44.jar并确保trust="true"已设置。

Answer 4

确保您给予trust =“true”

<sshexec trust="true"
           host="host_ip"        
           verbose="true/false"
           username="UserName"
           keyfile="KeyFile_location"                     
           command="some_command">
</sshexec>

Ant无法找到我的JAR文件？试图做一个sshexec任务
