[BUG] Launch arguments are ignored, unable to run using Gradle

I've been trying to setup Forge 1.7.2 Gradle with Netbeans without success so far. You can see the steps I've taken here.

The command I added:

-Pargs="--tweakClass cpw.mods.fml.common.launcher.FMLTweaker --version 1.6"

The main problem is, that even though I have correctly added the command-line parameters for the tweaker class (according to all sources on Gradle that I could find), Forge still uses the vanilla tweaker, and I cannot figure out why. And there is no error message (except for the vanilla error) that would help me on finding the issue.

It would be great if anyone could help me on this problem.

In addition I think it would be a good idea to add the correct tweaker class parameter to the setupdev task, because every dev will have to set that parameter otherwise by hand. So setting it by default might reduce the amount of 'Gradle doesn't work' topics.

The only IDE we officially support is eclipse, and we ship the runtime configs for it.

Anyone who goes through another IDE does so at there own risk/volition.

Not sure why you're trying to go through gradle to start the game, your ide should be perfectly capabile of launching java with whatever arguments you give it...

Because the Gradle-Plugin expects the game to be launched with a Gradle call. Which kind of makes sense, since otherwise I would have to break out of the entire Gradle-concept just to launch the application.

This as well renders the concept of an Eclipse support pointless, because Gradle is Gradle and independent from the IDE used if implemented correctly.

With your hint that the Forge build scripts actually do not define a proper run task, I tried to rule out all IDE problems by disabling the internal tasks and then writing my own run according to the official Gradle documentation:

apply plugin: 'java'

task(run, dependsOn: 'classes', type: JavaExec) {
  classpath = sourceSets.main.runtimeClasspath
  main = 'net.minecraft.launchwrapper.Launch'
  args '--version 1.6 --tweakClass cpw.mods.fml.common.launcher.FMLTweaker --accessToken FML'
  jvmArgs '-Xincgc -Xmx1G -Xms1G -Dfml.ignoreInvalidMinecraftCertificates=true'
}

And again the command-line parameters are ignored and the run fails, because Forge still uses the VanillaTweaker.

I would now consider this a bug.

hmmm

fine, il add a gradle run task for the client and the server... Please make an issue on the ForgegRadle github, I will close the issue when It is complete.
