Mac distribution of Eclipse RCP application built with Tycho on Windows doesn't start

I have built an Eclipse RCP application (Indigo) with Tycho. The build is run on a Win 7, 64-bit machine.

The parent POM includes:

<plugin>
  <groupId>org.eclipse.tycho</groupId>
  <artifactId>target-platform-configuration</artifactId>
  <version>${tycho-version}</version>
  <configuration>
  <resolver>p2</resolver>

  <environment>
    <os>linux</os>
    <ws>gtk</ws>
    <arch>x86_64</arch>
  </environment>
  <environment>
    <os>win32</os>
    <ws>win32</ws>
    <arch>x86_64</arch>
  </environment>
  <environment>
    <os>macosx</os>
    <ws>cocoa</ws>
    <arch>x86_64</arch>
  </environment>

The product configuration looks like this (with a few omissions and extra line breaks for readbility):

<product name="My App" uid="myapp.product" id="myapp.core.product" application="myapp.core.application" version="0.1.4.qualifier" useFeatures="true" includeLaunchers="true">

The build runs without problems, and generates zip files, which, unpacked on the target OSs Windows & Linux include working launchers. (On Linux, I have to make the launcher executable before being able to run it.)

On Mac OS X (10.6.8), however, the launcher (myapp.app) does nothing...

When I run java -jar -XstartOnFirstThread plugins/org.eclipse.equinox.launcher_[version], the application is launched, albeit without the splash screen.

I imagine I have a wrong setting anywhere in my Product Configuration, but I cannot mind which.

Solution

  • Cross-platform build on Windows for Mac is not expected to work. The reason is that Tycho/p2 would need to simulate a file system with Unix permissions. There is a request for this in Tycho's issue tracker, but IMHO implementing this is not worth the effort.
