How to send Jenkins build number as parameter in shell command which will get executed after build ends

Question

i am running a python script every time, after a Jenkins build fails or gets aborted. In that script i want to pass the Build Number so that i have this info in the script and use it accordingly.

Can someone help me please to understand how i should pass this build number as parameter to my shell command?

Answer 1

You shoud use "Execute Windows Batch Command" if you access enviornment variable using % .
Using "Execute Windows Batch Command" you can use as below:

echo %BUILD_NUMBER%
C:\\Python38\\python.exe C:\\python-workspace\\hello_test.py %BUILD_NUMBER%

If you want to execute with shell then you can access using $ as $BUILD_NUMBER

Answer 2

You are using the Postbuild Task plugin which executes the script as a shell script, and therefore you should use the shell parameter syntax which is $YOUR_PARAM

In your case just update your code to use $BUILD_NUMBER instead of %BUILD_NUMBER%
