You can use a post-commit hook.
Put the post-commit hook script in the hooks folder, create a wget_folder in your C:\ drive, and put the wget.exe file in this folder.
Add the following code in the file called post-commit.bat
SET REPOS=%1
SET REV=%2
FOR /f "tokens=*" %%a IN (
'svnlook uuid %REPOS%'
) DO (
SET UUID=%%a
)
FOR /f "tokens=*" %%b IN (
'svnlook changed --revision %REV% %REPOS%'
) DO (
SET POST=%%b
)
echo %REPOS% ----- 1>&2
echo %REV% -- 1>&2
echo %UUID% --1>&2
echo %POST% --1>&2
C:\wget_folder\wget ^
--header="Content-Type:text/plain" ^
--post-data="%POST%" ^
--output-document="-" ^
--timeout=2 ^
http://localhost:9090/job/Test/build/%UUID%/notifyCommit?rev=%REV%
where Test = name of the job
echo is used to see the value and you can also add exit 2 at the end to know about the issue and whether the post-commit hook script is running or not.
