Hi,

When I am trying to resolve my bower components I am receiving the error: "fatal: Unable to read current working directory: No error".
Can you assist ?

See the build log https://appharbor.com/applications/skeletonmvc/builds/1742490 for the error.

   Hi there,

   Apologies for the slow response. This one took some digging, but it turns out that this error is returned from Git, which is being invoked by npm/bower. This won't cause issues locally as you're likely running and building the project from a git repository and have access to all folders on your system.

   When your app is built on AppHarbor we'll just fetch a tarball from GitHub containing the source files to build. This means that the current working directory for your build.ps1 script is not a git repository. Git will then recursively inspect folders up until the root path, but doesn't have permissions to do so (as the user account processing your builds has restricted filesystem access).

   We might be able to mitigate this issue on our end at some point, but for now you can handle it pretty easily: Just initialize a git repository in your build.ps1 script before running any of the bower/npm commands. This way Git won't traverse the whole directory tree and can continue processing as usual. So just add this somewhere in the beginning of the build.ps1 script:

   git init
   

   Also, please note that builds on AppHarbor use an output directory that's different from the input directory. Currently your script operates on the input folder, but it doesn't seem to copy any files to the web project output directory. Depending on how you use bower you might be able to just copy the files after the build has completed. For instance, you could add something like this to the same post build event where you copy the roslyn compiler:

   if not exist "$(WebProjectOutputDir)\bower_components" md "$(WebProjectOutputDir)\bower_components"
   start /MIN xcopy /s /y /R "$(MSBuildProjectDirectory)\bower_components\*.*" "$(WebProjectOutputDir)\bower_components"
   

   I hope this helps. Let me know how it works out!

   Best,
   Rune
