sshexec with keyfile
i'm trying to use sshexec with a keyfile. i generated a key on the remote
server using the ssh-keygen -t dsa. this gave me a ~/.ssh/id_dsa and
~/.ssh/id_dsa.pub. i pulled the id_dsa.pub file to the remote machine from
where i want to run the sshexec task. i put the file into the
<property name="remote.host" value="remoteserver" />
<property name="remote.user" value="username" />
<property name="remote.key" value="id_dsa.pub" />
<sshexec host="${remote.host}" username="${remote.user}" keyfile="${
remote.key}" passphrase="" command="ls -lt"/>
and ant fails with the following message:
buildfile: D:\dev\workspace\autodeploy\build.xml
test.key:
[esshexec] Identity: java.io.FileNotFoundException: id_dsa (The system
cannot find the file specified)
BUILD FAILED
D:\dev\workspace\autodeploy\build.xml:687: com.jcraft.jsch.JSchException:
java.io.FileNotFoundException: id_dsa (The system cannot find the file
specified)
Total time: 1 second
any ideas would be most appreciated.

before you try and get SSH to work with ant, make sure it works on the
command line (or putty, on windows). That way you can be sure that
everything works.
-you dont need the private key on the remote box (consider removing it
for security)
-try using <property location="path to id_dsa" > not property value.
Then echo it, to make sure it is really what you think

RE: CVS failure notification..
Posted by Rizwan Merchant <ri...@alpha-it.com>.
Well, my intention is not to email each developer involved, but certain
selected people for the various tasks (cvs checkout, copiling source code,
building db, etc). then those people can review the problem they are
assigned to and delegate to appropriate developer(s).
i guess my work is going to be tedious, there is no smooth way of doing
this. I still feel that it would be best if ant would allow us to set a
property for each task in case of error. that would make it much smoother.
Thanks,
-Riz.

Well, the usage of loggers and listeners is pretty
straightforward, just give -logger option to the ant
launching script:
ant -logger fully.qualified.class.name
or in the case of MailLogger
ant -logger org.apache.tools.ant.listener.MailLogger
-propertyfile my_MailLogger.properties
where my_MailLogger.properties contains the setting
needed by MailLogger.
Let me ask you: why do you want to do this? It is a
good idea to have the developers informed that the
part from the build.xml they are responsible for is
not working. However, in order to send a useful report
you should collect info about the machine on which the
build script is running (at least its hostname, to
know where this report comes from), than java version,
ant version. Next, even if the developers receive that
error mails, the fault might not be theirs - the most
simple example is a guy writing some non-compiling
java code, then the compile target fails of course and
the guy that has written the compile targets gets an
email?!! What are they supposed do then - go and
correct the first guy's wrong code?

RE: CVS failure notification..
Posted by Rizwan Merchant <ri...@alpha-it.com>.
you are right, I have several different targets and need to capture errors
and notify people of any errors that may occur during the build process. My
problem is that depending on the target, different people need to be
notified of different errors. This is why I have to check every target
seperately.
I looked through Mailloggers..it doesnt seem to have the capability to send
out emails based on specific target errors..i.e
error on target 1 --> send email to person 1
error on target 2 --> send email to person 2
.
.
. and so on..
is this correct, or am I missing something?
Also, there doesnt seem to be any concrete examples of how to use
Mailloggers on the ant site..
Thanks a lot, appreciate your help.

Hello,
As far as I can see you are trying to capture the
output of some task and send emails if something goes
wrong. I would suggest to have a look ant loggers and
listeners[1] and especially at MailLogger[2] which
collects the output of the whole build process and
mails it. You can control it to send mails only on
build failures.
Now regarding <javac>: first of all if you want to
process its output you should set its failonerror
attribute to false; by default compile errors fail the
whole build (and it should be so). I also forgot to
tell you there is a <record>[3] task which lets you

You already know how to search the output from a task
captured in a file. This may be a tedious process if
you do it for each possible part and investigating
MailLogger in your case may be more useful

Thanks Ivan, I will try that. will the same work for javac task? I noticed
there is no "output" or "error" attribute for the javac task. how would i
send a failure notification email if javac fails?
wouldnt it be simpler if ant had the functionality to set a property for
each task in case of failure? then we can just test the property and go
about doing what we want...

Hello,
one way to do this is to use error and output
attributes of <cvs> task (quote from [1]):
output - the file to direct standard output from the
(cvs) command.
error - the file to direct standard error from the
(cvs) command
So you can store the error in a text file, than load
that file as a property and check whether it
<condition>[2] whether contains a given error message.
Here is the pseudo code:
<cvs command="checkout"
cvsRoot=":pserver:anoncvs@cvs.apache.org:/home/cvspublic"
package="my_module"
dest="${checkout.dir}"
error="${cvs.error.file}"
/>
<loadfile property="cvs.error.msg"
srcfile="${cvs.error.file}"/>
<condition property="cvs.error">
<contains string="${cvs.error.msg}"
substring="<cvs_error_msg_that_might_be_returned>">
</condition>
The problem in this approach is that you should find
all possible cvs_error_msg_that_might_be_returned.
Well, you can also do the following: if the error file
is created, then obviously there is an error while
checking the module out. Instead of trying to find the
exact error, mail the whole error file :)

Hello,
one way to do this is to use error and output
attributes of <cvs> task (quote from [1]):
output - the file to direct standard output from the
(cvs) command.
error - the file to direct standard error from the
(cvs) command
So you can store the error in a text file, than load
that file as a property and check whether it
<condition>[2] whether contains a given error message.
Here is the pseudo code:
<cvs command="checkout"
cvsRoot=":pserver:anoncvs@cvs.apache.org:/home/cvspublic"
package="my_module"
dest="${checkout.dir}"
error="${cvs.error.file}"
/>
<loadfile property="cvs.error.msg"
srcfile="${cvs.error.file}"/>
<condition property="cvs.error">
<contains string="${cvs.error.msg}"
substring="<cvs_error_msg_that_might_be_returned>">
</condition>
The problem in this approach is that you should find
all possible cvs_error_msg_that_might_be_returned.
Well, you can also do the following: if the error file
is created, then obviously there is an error while
checking the module out. Instead of trying to find the
exact error, mail the whole error file :)

How do I detect this error in ant? Say the password on the cvs account is

Any ideas? Pls help.

you need to set the remote key to the location of the private key you

you cannot assume that <scp> will know to look into ~/.ssh, because it
