Re: Error using psake.ps1 helper script

[James Kovacs]

Thanks for the investigations and reports everyone. I couldn't find a way to support both the splatting operator and named parameters. Seems they don't play well together. The solution that I came up with - if someone has a better solution, I'd love to hear it - is to duplicate the parameters from invoke-psake in psake.ps1 and then call invoke-psake with those parameters. You can find it on master or specifically this commit:

http://github.com/JamesKovacs/psake/commit/64ea235ff890f013427b93551681ad94f3d0c7f1

I'll let people try it out for a bit to ensure that it doesn't introduce other problems. If everyone is happy with the change and no one has a better implementation, I'll release psake 4.01 with the various small fixes so far.

Thanks,
James

Hi

Sorry for my late reply!
Thank you very much for your replies!

Dustin, I actually learned a lot from your posting. I'm new to
PowerShell and I had never heard of Trace-Command. Very valuable.
I guess I will rely on positional parameters then. It's not as
readable, but I need to have a lot of different tasks run on different
environments, so I'd like to have a central runner script (it will
host a more than the original psake.ps1 file).

Thank you again!
