How to upload file in Jenkins build pipeline | Jenkins build with file parameter option

Can I upload excel file or pdf file using the above code?

Can I upload Jar or dependency file using file parameter?

how to write the parameter value to a Java file from the Jenkins pipeline job, for example - If I have some value getting selected from the name parameter as a checkbox, I want that value to be written in the Java file on a workspace, via groovy declarative script

thank you doc

Hey, will you plz make a video on file upload in the pipeline project instead of the freestyle project? otherwise plz share the steps in the comment reply itself... I have tried but the uploaded file is not available in the workspace. I'm using Jenkins 2.387.2 ..but not working.. Thanks ..

I want to share the number of execution results in email, so how to fetch that number from the log file, could you please help me

Instead of power shell, use shell script to read the data from the file and print in console output

Could you please explain how to trigger the file parameterized jenkins job via rest api ? How to pass a local file from our system as parameter to jenkins job through api params ?
