Path is created incorrectly.

[haefele]

Let's assume a project structure like the following:

• Root
  • MyProjectRoot
    • src
      • MyProject.sln
      • ...
    • tools
      • cake
        • cake.exe
        • ...
    • scripts
      • build.cake
      • build.ps1

My build.ps1 script looks like:

cd ..\tools\cake
.\Cake.exe .\..\..\scripts\build.cake -verbosity=diagnostic

I think my intention is clear: I want to execute my build.cake script.

But it looks like he creates the full-path to the build.cake file incorrectly.
The output is:

Creating script session...
Processing build.cake...
Could not find script "Root/scripts/build.cake".

It looks like he initially found my build.cake file, but later he creates the path incorrectly and obviously can't find it at the new path.
This is one folder too much upwards in the folder hierarchy.

So then I try to remove one .. from my path to build.cake:

cd ..\tools\cake
.\Cake.exe .\..\scripts\build.cake -verbosity=diagnostic

But sadly, this doesn't help either.
Because now, he fails with another error.
The output is:

Could not find a part of the path "MyProjectRoot/tools/scripts".

Okay, I didn't really expect that to work now, since that path can't be correct, it's one folder too much downwards in the folder hierarchy.

So it looks like, I have no way to get into my "MyProjectRoot" folder, to point the cake.exe to the correct script file.

Hmm, sounds strange. Will take a look at it later tonight.
Thank you for reporting this.

[patriksvensson]

@haefele I just tried this and it works as expected here. Would you mind posting your build.ps1 script here? Would help reproduce the behavior.

[haefele]

@patriksvensson Well, they are exactly like the ones above.
I will try to reproduce it on my end now.

[haefele]

@patriksvensson This is strange, it still doesn't work on my end.
FYI, I have version 0.1.32.0, the latest build I can get of github.

Maybe I can upload my folders somewhere?

[patriksvensson]

@haefele I just used the Cake Bootstrapper to generate a script and edited that one to use the folder structure you have.

Here is the script, try it out and see if it works on your end.

Param(
    [string]$Script = "build.cake",
    [string]$Target = "Default",
    [string]$Configuration = "Release",
    [string]$Verbosity = "Verbose"
)


$TOOLS_DIR = Join-Path $PSScriptRoot "../tools"
$NUGET_EXE = Join-Path $TOOLS_DIR "nuget.exe"
$CAKE_EXE = Join-Path $TOOLS_DIR "Cake/Cake.exe"
$PACKAGES_CONFIG = Join-Path $TOOLS_DIR "packages.config"

# Make sure tools folder exists
if ((Test-Path $PSScriptRoot) -and !(Test-Path $TOOLS_DIR)) {
    New-Item -path $TOOLS_DIR -name logfiles -itemtype directory
}

# Try find NuGet.exe in path if not exists
if (!(Test-Path $NUGET_EXE)) {
    "Trying to find nuget.exe in path"
    $NUGET_EXE_IN_PATH = &where.exe nuget.exe
    if ((Test-Path $NUGET_EXE_IN_PATH)) {
        "Found $($NUGET_EXE_IN_PATH)"
        $NUGET_EXE = $NUGET_EXE_IN_PATH 
    }
}

# Try download NuGet.exe if not exists
if (!(Test-Path $NUGET_EXE)) {
    Invoke-WebRequest -Uri http://nuget.org/nuget.exe -OutFile $NUGET_EXE
}

# Make sure NuGet exists where we expect it.
if (!(Test-Path $NUGET_EXE)) {
    Throw "Could not find NuGet.exe"
}

# Save nuget.exe path to environment to be available to child processed
$ENV:NUGET_EXE = $NUGET_EXE

# Restore tools from NuGet.
Push-Location
Set-Location $TOOLS_DIR

# Restore packages
if (Test-Path $PACKAGES_CONFIG)
{
    Invoke-Expression "$NUGET_EXE install -ExcludeVersion"
}
# Install just Cake if missing config
else
{
    Invoke-Expression "$NUGET_EXE install Cake -ExcludeVersion"
}
Pop-Location
if ($LASTEXITCODE -ne 0)
{
    exit $LASTEXITCODE
}

# Make sure that Cake has been installed.
if (!(Test-Path $CAKE_EXE)) {
    Throw "Could not find Cake.exe"
}

# Start Cake
Invoke-Expression "$CAKE_EXE `"$Script`" -target=`"$Target`" -configuration=`"$Configuration`" -verbosity=`"$Verbosity`""
exit $LASTEXITCODE

@patriksvensson Your script seems to work, but I can't tell why mine is not.
Shall I upload my folders and scripts somewhere, so you can easily test my case?

[patriksvensson]

Yes, that would be good. There must be a rational explanation for this :)

[haefele]

I hope you can work with a onedrive file 😃.

Perfect. The problem seem to have something to do how Powershell handles working directories when launching a process like that. Maybe @devlead know something about this?

Anyway, you can get your script working correctly by running it like this:

.\..\tools\cake\Cake.exe build.cake -verbosity=diagnostic

[haefele]

This is just so strange, because I can get one folder upwards or downwards of the actual folder I want to get to.
Anyways, that seems to do the trick.

Thank you very much!

And especially thanks for the amazing fast help!

[patriksvensson]

Will investigate this further to make sure that this is not a problem with Cake.
Anyways, glad that you got it running!
