获取Eclipse RCP Mac应用程序以显示初始屏幕

Question

I've tried everything, spent hours on this, created rcp example projects from eclipse downloaded for mac and selected show splash and for the life of me I cannot get my splash screen to show up. I've tried the following:

1. In product definition select the plugin that contains splash.bmp in root
2. Added show splash in plugin_customization.ini
3. Tried to use the default eclipse splash.bmp to ensure my bmp file is not corrupted.

Its frustrating that the eclipse rcp wizard when selecting show splash screen does not work out of the box and really need this for my release, any help would be appreciated. I have literally searched all of google.

By default, the splash screen is made visible by the executable even before the Java VM is started ( here is the C code for macOS that does this ).

If you bypass the executable by calling directly Java ( java -jar plugins/org.eclipse.equinox.launcher_... ), you have to use the command line argument -showSplash <path-to-splash.bmp> (either with an absolute path starting with / or a releative path relative to your current working directory). By bypassing the executable, also <executable>.ini is not read and all arguments must be specified on the command line instead.

If using the executable , the splash screen location is specified in the config.ini ( osgi.splashPath=platform\\:/base/plugins/<plugin_containing_splash.bmp> ). In plugin_customization.ini it can be specified whether a progress bar is displayed at a later time during startup ( org.eclipse.ui/SHOW_PROGRESS_ON_STARTUP=true ).

Make also sure the splash screen BMP is in 24-bit format (8R, 8G, 8B) . Otherwise, the splash screen will not be displayed or with the wrong colors.

Since Eclipse itself is also an RCP application, you can see how Eclipse does it and experiment with it, eg trying to start the Eclipse IDE via java ... and showing a different splash screen ( "MONKEY SEE/MONKEY DO RULE - Always start by copying the structure of a similiar plug-in" ).
