ANT 找不到特定的库 [英] ANT can't find specific libraries

问题描述

我正在尝试使用 SSHEXEC ANT 任务，它需要 JSCH 库.

I am trying to use the SSHEXEC ANT task, which requires the JSCH library.

当我尝试使用 SSHEXEC 任务时，我得到以下信息:

When I try to use an SSHEXEC task, I get the following:

BUILD FAILED
/home/www/test/build/build.xml:140: 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
        -/root/.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

我已经把jsch-0.1.50.jar(最新的)放在/usr/share/ant/lib，/root/.ant/lib 甚至尝试了以下操作:

I have placed jsch-0.1.50.jar (the latest) in /usr/share/ant/lib, /root/.ant/lib and even tried the following:

ant my-sshexec-target-name -lib /path/to/jsch-0.1.50.jar

而且我不断收到同样的错误.我还尝试在所有相同位置将文件重命名为 jsch.jar.结果一样.我在这里做错了什么?

And I keep getting the same error. I have also tried renaming the file to simply jsch.jar in all the same locations. Same result. What am I doing wrong here?

更新

我还运行了 ant -diagnostics 并看到了这个:

Also I ran ant -diagnostics and see this:

注意:sshexec:不可用(不存在实现类)

这是什么意思?

推荐答案

将 ANT_HOME 设置为/usr/share/ant/

Set ANT_HOME to /usr/share/ant/

export ANT_HOME=/usr/share/ant/
