Tools for Apache Cordova Builds Fail on TFS

Question

I'm receiving errors building a Cordova app on TFS 2013. Specifically, it always fails doing some sort of operation on a platform-specific screen.png file. Other posts talk about the problem being related to the file being marked as read-only, but I've been unable to use any of the few solutions I found to get the build to work. Any ideas?

Answer 1

I finally found a solution. I added a before_prepare hook to remove the read only flag from the files. I added the file hooks/before_prepare/undoReadOnly.bat with the contents below. Note that I had to edit these outside of Visual Studio and save them with ANSI encoding for TFS to be able to read them:

echo before_prepare hook - undoReadOnly
echo MSBuildProjectDirectory=%MSBuildProjectDirectory%
attrib -r %MSBuildProjectDirectory%\MyApp\platforms\*.* /S /D
