Jenkins Pipeline bat multiple lines

Question

According to the docs, one can have multiple lines in the script paramater of bat.

However, I've tried the following in my stage steps and only the first line gets executed.

Declarative pipeline:

...
bat """
    c:\path\to\conda activate my_env
    cd c:\path\to\scripts
    python myscript.py ${some_arg}
"""
...

Scripted pipeline:

...
bat(
    returnStdout: true, 
    script: """
        c:\path\to\conda activate my_env
        cd c:\path\to\scripts
        python myscript.py ${some_arg}
    """
)
...

What do I need to do to get all the lines to execute sequentially?

PS
I know I can chain the commands into a single line with "&" but that quickly becomes unreadable with lots of commands.

You need to add the keyword call, whereever you are invoking Windows batch scripts (.bat or .cmd), else the executed batch file won't return control. E.g.:

...
bat """
    call c:\path\to\conda activate my_env
    cd c:\path\to\scripts
    call python myscript.py ${some_arg}
"""
...
