Command line invocation on Windows

[tschulz3016]

The command line build does not work at all for me (1.5.8 and current nightly, on Windows 7).

I'm, running:

<path_to_arduino>\arduino.exe  myproject.ino

or:

cd <arduino_path>
arduino.exe  <some_path>\myproject.ino

The IDE produces a dialog box with "Cannot specify any sketch files".
Same happens if arduino_debug.exe is used. Option --verbose does not give any additional information.

Are you sure you're not specifying any other options? Looking at the code, this error message should only be possible when specifying options (e.g. like --verbose). Without options and with just a .ino file, this should not happen.

Right, that message "Cannot specify any sketch files" comes up only when called with -v.
When calling just like this:

\w\arduino-nightly-indows\arduino-nightly\arduino.exe mystep.ino

I'm getting a dialog with "Failed to open sketch: "mystep.ino". Then the IDE opens with a new sketch.

Same happens when I use --verify.
As I understand, I should be able to compile and upload the sketch from the command line? Let me know if I can assist. I would find the command line very useful indeed.

You'll need to provide a full path to your .ino file. When starting Arduino, the current directory is changed to the install directory for some java stuff to load properly. On Linux there is a workaround for this, but not for Windows or OSX yet. See #1493 for details about this issue.

Ok that seems to work for me now. Thank you.
It is worthwhile pointing out that the path to the project file needs to start with the drive letter like:

   \w\arduino-nightly-indows\arduino-nightly\arduino.exe  C:\Projects\arduino\mystep\mystep.ino 

This is although the current drive is already C: and there are no other drive letters in use on my machine. Without the drive letter, I'm still getting the error.
