Testing FML loading plugins with Eclipse

    Hello guys,

    I'm trying to make an FML loading plugin, aka core mod. Right now it should not do anything but print a message to indicate that it has been successfully loaded.
    It does work when I build it and put it into the mods folder, but when I launch the game straight from Eclipse it seems like FML is completely ignoring the plugin. I don't want to have to build it every time to test it.

    I did specify the option "-Dfml.coreMods.load=name.of.my.Class".
    Somewhere in the log it reads "Completely ignored arguments: [-Dfml.coreMods.load, name.of.my.Class]". Is that bad?

    Greetings and thanks,

    Okay I found out how to do it, it was mentioned in a tutorial:
    I created a "dummy" JAR file with nothing but a META-INF folder containing a MANIFEST.MF file with the following content:
    Manifest-Version: 1.0
    FMLCorePlugin: name.of.my.Class
    FMLCorePluginContainsFMLMod: true
    and put this dummy jar into the eclipse/mods folder.

    You were close, you just needed to put the "-Dfml.coreMods.load=name.of.my.Class" in the VM arguments, not program arguments. But the dummy jar is a neat way that I didn't consider.

    Darnit! So close.
    That once again shows what a noob I am :D now it makes sense to me since the program arguments are passed to the main function.
