Welcome to the Project Build Environment.

Below is a list of built targets available. Read the details before compiling, it may matter. To build a given target, just call `build.ps1 -Target <T>`.
Happy coding.

=================================================================================================================================================================================================
Project.DevServer                       - Compiles the Project Development Server, which can be easily used for quick and dirty local development.
Constants.Vault                          - Generates the necessary constants for building, and then resets the files. Not for direct use as it will generate the files then immediate reset them.

[Roadrunner67]

@devlead Where is the best place to put a unit test with a custom build.cake to provoke this issue?

[patriksvensson]

@Roadrunner67 Try quoting the target: .\build.ps1 -Target "Project.DevServer" and see if it works. Looks like the command line arguments sent to the program sees Project.DevServer as two arguments.

[Roadrunner67]

Quotes don't help. The VS Code Cake extension already quotes the targets BTW.

[Roadrunner67]

OK, the problem lies with build.ps1 if I call cake.exe directly it is a non-issue.

[Roadrunner67]

Build.ps1 line 246:

$cakeArguments = @("$Script"); if ($Target) { $cakeArguments += "-target=""$Target""" } if ($Configuration) { $cakeArguments += "-configuration=$Configuration" }

..instead of..

$cakeArguments = @("$Script"); if ($Target) { $cakeArguments += "-target=$Target" } if ($Configuration) { $cakeArguments += "-configuration=$Configuration" }

.. fixes the problem - not sure where build. ps1 lives though

[devlead]

@Roadrunner67 the bootstrappers reside in the https://github.com/cake-build/resources/ repo.

[Roadrunner67]

@devlead my PR #79 fails on AppVeyor, but I have no clue what the problem is.

[devlead]

Looks like it fails if no script is supplied.

[Roadrunner67]

@devlead ok, got it - ready for approval

[devlead]

fixed by #80
