As you can see from output console. I have made some progress by updating
the remote raspberry pi operating system.
I am not sure what parameter is required to resolve this error message
*com.jcraft.jsch.JSchException:
reject HostKey: 192.168.0.22 *.
I am pretty sure it is this code
<sshexec host="${raspberrypi}"
username="${username}"
password="${password}"
failonerror="true"
usepty="true"
verbose="true"
command="java -Xdebug
-Xrunjdwp:server=y,transport=dt_socket,address=4000,suspend=y -jar
${jar.filename}" />

I think the error is earlier while <scp>ing the jar to the PI.
It seems that an sshd is running on the pi.
Are you sure you have the right credentials? Could you login with this
username+password?
Also you could run Ant with -verbose or -debug to get more details.
The error
com.jcraft.jsch.JSchException: SSH_MSG_DISCONNECT: 2 Too many
authentication failures
comes from the underlying ssh library (jsch). But a little bit
Googling shows that the most
common problem is a wrong username/password.

Betreff: sshexec defaults to port 22
Hi,
I am trying to setup Eclipse Remote development on raspberry pi for
Java as per this page
. http://www.raspirecipes.org/archives/218
Unfortunately something has changed since he did . I have managed to
correct one of the errors.
I suspect this second error is due to the sshexec command in the
remotedebug.xml ant build script.
For me the error message is indicating that it defaults to ssh port 22.
I hope somebody here who has an in depth understanding of sshexec
ant command can give me
the information needed to complete my project.
my eclipse console error message is :
*Buildfile: /home/zahid/Eclipse Java
