appbundler

A fork of the Java Application Bundler with the following changes:

The native binary is created as universal (32/64)
Fixes icon not showing bug in JavaAppLauncher
Adds LC_CTYPE environment variable to the Info.plist file in order to fix an issue with File.exists() in OpenJDK 7 (Contributed by Steve Hannah)
Allows to specify the name of the executable instead of using the default "JavaAppLauncher" (contributed by Karl von Randow)
Adds classpathref support to the bundleapp task
Adds support for JVMArchs and LSArchitecturePriority keys
Allows to specify a custom value for CFBundleVersion
Allows specifying registered file extensions using CFBundleDocumentTypes
Passes to the Java application a set of environment variables with the paths of the OSX special folders and whether the application is running in the sandbox (see below).
Allows overriding of passed JVM options by the bundled app itself via java.util.Preferences (contributed by Hendrik Schreiber)
Allow setting custom Info.plist properties (e.g. SUFeedURL for Sparkle) (contributed by Morgan Schweers)
Provide an option to make the application able to open arbitrary HTTP endpoints.
Format the Info.plist XML file nicely.
Add JNI files to the class path.
Allow the {bundle}/Java directory to be added as a class path entry.

These are the environment variables passed to the JVM:

LibraryDirectory
DocumentsDirectory
CachesDirectory
ApplicationSupportDirectory
SandboxEnabled (the String true or false)

Example:

<target name="bundle">
  <taskdef name="bundleapp" 
    classpath="appbundler-1.0ea-cf2.jar"
    classname="com.oracle.appbundler.AppBundlerTask"/>

  <bundleapp 
      classpathref="runclasspathref"
      outputdirectory="${dist}"
      name="${bundle.name}"
      displayname="${bundle.displayname}"
      executableName="MyApp"
      identifier="com.company.product"
      shortversion="${version.public}"
      version="${version.internal}"
      icon="${icons.path}/${bundle.icns}"
      mainclassname="Main"
      copyright="2012 Your Company"
      applicationCategory="public.app-category.finance">
      
      <runtime dir="${runtime}/Contents/Home"/>

      <arch name="x86_64"/>
      <arch name="i386"/>

      <bundledocument extensions="png,jpg"
        icon="${icons.path}/${image.icns}"
        name="Images"
        role="editor">
      </bundledocument> 

      <bundledocument extensions="pdf"
        icon="${icons.path}/${pdf.icns}"
        name="PDF files"
        role="viewer">
      </bundledocument>

      <bundledocument extensions="custom"
        icon="${icons.path}/${data.icns}"
        name="Custom data"
        role="editor"
        isPackage="true">
      </bundledocument>

      <!-- Workaround since the icon parameter for bundleapp doesn't work -->
      <option value="-Xdock:icon=Contents/Resources/${bundle.icon}"/>

      <option value="-Dapple.laf.useScreenMenuBar=true"/>
      <option value="-Dcom.apple.macos.use-file-dialog-packages=true"/>
      <option value="-Dcom.apple.macos.useScreenMenuBar=true"/>
      <option value="-Dcom.apple.mrj.application.apple.menu.about.name=${bundle.name}"/>
      <option value="-Dcom.apple.smallTabs=true"/>
      <option value="-Dfile.encoding=UTF-8"/>

      <option value="-Xmx1024M" name="Xmx"/>
