StartProcess cannot find specified file using native StartProcess or using Powershell version.

[jenaewhitmore]

What You Are Seeing?

Using StartProcess returns "An error occurred when executing task 'taskName'.
Error: One or more errors occurred.
The system cannot find the file specified"

StartProcess("//ComputerName/SomeFolder/Some.exe")

This same error appears when using the Powershell addin that uses a script file that invokes Start-Process.

What is Expected?

The process should be started. As it works outside of cake just using straight powershell.

What version of Cake are you using?

26.1.0

Are you running on a 32 or 64 bit system?

64

What environment are you running on? Windows? Linux? Mac?

Windows

Are you running on a CI Server? If so, which one?

Not yet, just local testing

How Did You Get This To Happen? (Steps to Reproduce)

Task("taskName")
    .Description("start exe")
    .Does(() =>
    {
        StartProcess(@"\\PCName\SomeFolder\Some.exe");
    });

@jenaewhitmore Cake currently doesn't support UNC paths. Possible workarounds for this at this moment are i.e.

1. Mount network share to drive letter
2. Utilize cmd to start, something like StartProcess("cmd", @"/c \\PCName\SomeFolder\Some.exe");
3. Use .NET Build in process start

I have a similar issue except I'm not using UNC paths.
The parameter I pass to StartProcess is like so:

var code = StartProcess("npm", 
        new ProcessSettings
        {
            Arguments = new ProcessArgumentBuilder()
                .Append("run")
                .Append("build-all-prod"),
         });

Even though I'm able to get the process to work in powershell or in any other command line I'm unable to call it in the cake build.

When I use "git" as a parameter it works as a normal shell command would.

I was able to get this figured out - I just pushed the npm into the arguments appended. It was able to trigger off the step I was requesting.
Now the code looks like this for those interested:

var code = StartProcess("powershell",
        new ProcessSettings
        {
            Arguments = new ProcessArgumentBuilder()
                .Append("npm")
                .Append("run")
                .Append("build-all-prod"),
         });
