Call logoff in Ant script

Question

I am trying to call the logoff command from my build.xml. I tried several combinations in my ant target such as :

<target name="bat">
<echo>Executing batch script</echo>
  <exec dir="C:\WINDOWS\system32" executable="cmd">
    <arg value="/c"/>
    <arg value="logoff"/>
  </exec>
</target>

But everytime, I get this error : "logoff is not recognized as an internal or external command, operable program or batch file"

I don't know how to fix this issue. Thanks for helping.

EDIT:

logoff.xml

<?xml version="1.0"?>
<project name="logoff" default="off" basedir=".">
    <target name="off">
        <exec executable="cmd">
            <arg value="/c"/> 
            <arg value="logoff"/>
        </exec>
    </target>
</project>

logoff_xml.bat:

@echo off
set ANT_HOME=W:\lib\org.apache.ant
set JAVA_HOME=C:\Program Files (x86)\Java\jdk1.6.0_24 
set PATH=%PATH%;%ANT_HOME%\bin 
set BUILD_PATH=W:\logoff.xml 
set ANT=call ant -buildfile %BUILD_PATH% 
%ANT% 
pause

echo %PATH% (with buid.xml bat target)

[exec] C:\Outils\GPS_510\bin;C:\Outils\GNATPRO_6.1.2\bin;C:\WINDOWS\system3

t\bin

EDIT : When I launch logoff with Ant, I got :

[exec] Disconnecting
[exec] "logoff.exe is not recognized as an internal or external command, operable program or batch file"

Because, I'm running an Ant script periodically on a remote computer. I need to log off the remote session after build to avoid any conflict with the others. — Lycris, Sep 16 '13 at 15:16
Right... so what mechanism runs the ant build remotely? How are you checking it's status? I'm pretty sure you're going to have a better time doing the log off there than in the ant script itself. — thekbb, Sep 16 '13 at 18:20
I'm calling mstsc command since Jenkins. In the rdp file in parameter, I launch a batch script which calls the build. But I want to run the build periodically during the night for instance. The problem is why ant cannot find the logoff command whereas everything is in the PATH variable — Lycris, Sep 17 '13 at 06:18
Is there a reason you don't run the jenkins slave service on the machine you're wanting to run the build on? It would just work, you wouldn't have to mess with logging off. — thekbb, Sep 17 '13 at 14:22
I'm running jenkins slave agent on another computer exactly. I have some restrictions. But again, the problem is not here. When I launch a logoff from the console it's working and when I work with Ant it cannot be recognized, whereas simple "echo" works . Let's be clear I'm working in the remote session, no relation with Jenkins — Lycris, Sep 17 '13 at 15:25
wait... you have a jenkins master, a jenkins slave and then you're running the ant build on a third computer? I truly believe your real solution will be to not do crazy stuff. — thekbb, Sep 17 '13 at 15:49
Everything works truly (except logoff)... I tried the ant logoff in another computer and same problem. — Lycris, Sep 18 '13 at 06:47
I got the same error, then I removed JAVA_HOME and problem was solved... — Dusan Plavak, Sep 18 '13 at 14:59

I cannot possibly imagine why anyone would ever do this in a build script.

Please don't do this.

But if you do, don't exec cmd.exe - call logoff.exe directly

<project name="logoff" default="logoff" basedir=".">
    <target name="logoff">
        <exec executable="logoff" />
    </target>
</project>

It's a very safe assumption that logoff.exe is on %PATH%, if for some reason it's not, set a property to get the absolute path to logoff.exe;

<project name="logoff" default="logoff" basedir=".">
    <property name="system32.dir" location="C:\Windows\System32" />        

    <target name="logoff">
        <exec executable="${system32.dir}\logoff" />
    </target>
</project>

I feel dirty for having typed this.

You should remove that dir atribute.... This is working for me:

    <?xml version="1.0" encoding="UTF-8" ?>
    <project name="logoff" default="default" basedir=".">
        <target name="default">
        <exec executable="cmd">
            <arg value="/c"/>
            <arg value="logoff"/>
        </exec> 
    </target>
    </project>

EDIT:

@echo off
set ANT_HOME=W:\lib\org.apache.ant
set PATH=%PATH%;%ANT_HOME%\bin 
set BUILD_PATH=W:\logoff.xml 
set ANT=call ant -buildfile %BUILD_PATH% 
%ANT% 
pause

Thanks for the answer. But now, I have "logoff is not recognized as an internal or external command, operable program or batch file" in an infinite loop – Lycris Sep 16 '13 at 08:01
yes, maybe I have to set the PATH variable in the ANT target ? – Lycris Sep 16 '13 at 09:38
are you running ant script from cmd? Yes, that can be a solution to your problem, because it looks like cmd cant find it, coz not looking in right dirs... try also shutdown /l instead logoff as mentioned down.. – Dusan Plavak Sep 16 '13 at 09:47
are you running it from cmd? Which directories do you have in PATH? – Dusan Plavak Sep 16 '13 at 11:02
I'm running it from a bat which call the bat target (in build.xml) which call shutdown/logoff. – Lycris Sep 16 '13 at 11:10
But shutdown and logoff work perfectly when I launch it from a simple batch script – Lycris Sep 16 '13 at 11:15
It is strange. For me it is working... can you just upload somewhere exactly files which you are using and also echo of PATH? – Dusan Plavak Sep 16 '13 at 11:21
please edit your question and type it into 2 different code block so it is easy to read... so we know what is in which file – Dusan Plavak Sep 16 '13 at 11:44
can you post also that path variable? – Dusan Plavak Sep 17 '13 at 14:05
You could try it with `` – jeb Sep 18 '13 at 13:17

Try using shutdown /l /f instead, as suggested here:

This might also help (description how to do it in java) as ant uses similar (to java) arguments:
