Changelog

Releases are documented in GitHub.

Known Issues

• Creating the directory shortcuts to the Cordova platform-specific projects may fail when running in the Windows environment. The tool reports _"WARNING: Failed to create shortcut for Cordova platform: XXXX."__ where XXXX is ios, windows, or android. This is caused by an issue in Node.js which has been fixed in more recent releases. To resolve this issue, upgrade Node.js to the latest version.

• Adding the windows platform in the Linux and Mac OS environments fails. The tool reports "WARNING: Failed to add the Cordova platforms: XXXX." where XXXX includes windows. This is caused by an issue in the Windows platform for Cordova. Depending on the cordova-windows version, running the tool can show one of two errors: "Cannot find module 'Q'." or "No such file or directory.". Until this problem is fixed by Cordova, we've removed the windows platform from the default list when creating the app in Linux or Mac OS.

• Error when building an iOS application for projects generated in a Windows machine and then copied to an OS X machine. Xcode reports "Shell Script Invocation Error - Command /bin/sh failed with exit code 126". This happens when the execution permission (+x) is lost on some scripts when copying between the different file systems.

  To resolve this, open a Terminal window in OS X and execute the following command to restore the executable bit on the script.

  chmod +x [path to the PWA Builder project]/cordova/platforms/ios/cordova/lib/copy-www-build-step.sh
  

• Issues in Visual Studio 2015 RC with the Windows solution generated by Cordova:

  • Opening the CordovaApp.sln solution file might hang Visual Studio while loading the Windows 8 project. As a workaround, remove the Windows 8 project file from the solution.
  • When building the solution, Visual Studio reports the following error in the Windows 10 project: "'ValidateAppxManifest' failed. Unspecified error". As a workaround, clean and rebuild the solution.
