           Summary: SSHExec task: output disappears
           Product: Ant
           Version: 1.6.5
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Optional Tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: [EMAIL PROTECTED]


The output of a remotely executed command does not appear reliably. It seems as 
if only the first usage of sshexec within a built logs the output of the remote 
command.

The following build file part reveals the error:

        <target name="copyScript">
                <property name="local.test.script" value="C:\Temp\test.sh"/>
                <echo file="${local.test.script}">
echo "Output to stdout" 
echo "Output to stderr" 2>&amp;1                        
                </echo>
                <scp file="${local.test.script}" 
remoteTofile="[EMAIL PROTECTED]:${remote.test.script}"  trust="true" 
keyfile="${user.home}/.ssh/id_dsa" passphrase=""/>
        </target>

        <target name="sshExecOrgStdoutStderr" depends="copyScript">
                <sshexec host="host" username="user" command="sh 
${remote.test.script}"  trust="true" keyfile="${user.home}/.ssh/id_dsa" 
passphrase="" outputProperty="ssh.out"/>                
                <echo message="Stdout/stderr: ${ssh.out}"/>
                <sshexec host="host" username="user" command="sh 
${remote.test.script}"  trust="true" keyfile="${user.home}/.ssh/id_dsa" 
passphrase="" outputProperty="ssh.out"/>                
                <echo message="Stdout/stderr: ${ssh.out}"/>             
        </target>

The output of this build target is:

sshExecOrgStdoutStderr:
  [sshexec] Connecting to host:22
  [sshexec] Output to stdout
  [sshexec] Output to stderr
     [echo] Stdout/stderr: Output to stdout
     [echo] Output to stderr
  [sshexec] Connecting to host:22
     [echo] Stdout/stderr: Output to stdout
     [echo] Output to stderr

The lines   
[sshexec] Output to stdout
[sshexec] Output to stderr
should also appear for the second call to sshexec. The outputProperty is not 
affected.

Here is a patch which uses the LogOutputStream in order to solve the issue.
