AntBuilder with optional scp task

[Pascal DeMilly (Groovy)]

I am having a problem understanding how to configure AntBuilder with optional
tasks

I am trying to execute this simple task

System.setProperty('ant.home', '/home/user/.ant')
def ant = new AntBuilder ()
scp ant.scp (file:"/tmp/test", todir:'user:pass@host:/tmp', verbose:true)

But I am getting:

Problem: failed to create task or type scp
Cause: the class org.apache.tools.ant.taskdefs.optional.ssh.Scp was not found.
        This looks like one of Ant's optional components.
Action: Check that the appropriate optional JAR exists in
        -/home/guest/.ant/lib
        -/home/guest/.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

Fair enough. My configuration is:

.groovy/lib:
        jsch-0.1.39.jar
.ant/lib:
        ant-jsch.jar

What else do I need?

Obviously calling groovy with "-cp ~/.ant/lib/ant-jsch.jar" works.

But why can't AntBuilder loads those jars for me.

TIA

Hi Pasca,

I had the same issue as well -- you need to install the 'optional' ant
task for SCP. Here's the page:
http://ant.apache.org/manual/OptionalTasks/scp.html
and you have to add the jsch.jar:
jsch.jar 0.1.29 or later  --    sshexec and scp tasks   --  
http://www.jcraft.com/jsch/index.html

I'm using Eclipse, so added the jar to my project and all was happy :-) .

Cheers,
-Chris

Thanks, I already tried this (see end of prior message)

My question was more related to not having to specify  those jars on the
command line but having AntBuilder acts like ant by loading all optional
tasks from home.ant System property when instantiated.

Thanks

Pascal

Sorry Pascal, missed that :-)

Thanks, I already tried this (see end of prior message)

My question was more related to not having to specify  those jars on the 
command line but having AntBuilder acts like ant by loading all optional 
tasks from home.ant System property when instantiated.
