Hudson - remote builds strange behaviour

[sebb <se...@gmail.com>]

There seem to be some odd happenings when JMeter tries to build remotely.

See the forwarded message, which says that the build failed because it
could not find:

java.io.IOException: Cannot run program "ant" (in directory
"<http://hudson.zones.apache.org/hudson/job/JMeter-trunk/ws/trunk")>:
java.io.IOException: error=2, No such file or directory

However, the Console output for the job says:

java.io.IOException: Cannot run program "ant" (in directory
"/home/hudson/hudson-slave/workspace/JMeter-trunk/trunk"):
java.io.IOException: error=2, No such file or directory

Is it possible to login to the slave to see what is really going on here?
