Creating a Mac bundle that uses Java 7

[melvin]

I'd like to share some experiences on creating a Mac bundle for Java 7. I'd also like to thank the Forge team for pushing through with the upgrade to Java 7, it was a lot easier to do the same for Magarena after seeing what Forge has done.

I've tried Oracle's appbundler as well but ran into problems, I didn't manage to debug it as I don't have access to a Mac. After more research I came across http://mjhutchinson.com/journal/2010/01 ... or_gtk_app. The idea of using shell script (instead of using a Mac binary like what the bundlers do) appeals to me.

I've modified the launcher script from the site for Magarena 1.42, see https://code.google.com/p/magarena/sour ... auncher.sh and changed the Info.plist file to refer to MagarenaLauncher.sh as the CFBundleExecutable property.

Finally the app bundle is a zip of a directory with a special structure, in Magarena's case it looks like the following

Code: Select all

Magarena-<version>.app
 - Contents
   - Info.plist
   - PkgInfo
   - MacOS
     - MagarenaLauncher.sh
   - Java
     - <contents of the Win/Linux release zip>

Hi all,

I have made a little progress on the Mac bundle for Java 7. Before, the Forge.app simply crashed immediately. Now I can get the splash screen but it hangs with this error.

The "Caused by: java.lang.RuntimeException: default directory must be absolute" line is the important one. I know the app is looking for the "res" folder. The Java 7 bundler directory structure and the way it handles paths are considerably different from the Java 6 way.

I'll dig into the code but if someone already recognizes the issue feel free to comment.

Thanks
Dave
