[[1.12] How do I do mod dependencies?]

What is the prefix of the .meta file? Is it the maven base + version, or the jar name without the .jar? E.g. somedep-0.8.meta?

[[1.13.2] Minecraft.getInstance() method not found]

Using gradlew build. This is similar to how the mod was built for 1.12.2 but it just used a shade configuration and included those dependencies directly. If I don't use shadow, then Minecraft.getInstance() works at runtime, but calls the the jxinput fail. As soon as I add the shadowJar task, Minecraft.getInstance() fails, almost like I'm getting a different version of Minecraft on the classpath.

Thanks will update. Still can't call Minecraft.getInstance() though.

[[1.13.2] Minecraft.getInstance() method not found]

I was missing Minecraft as a dependency in the mods.toml file. I took the #optional too literally

 

Adding minecraft as a dependency in the mods.toml file didn't help. 

 

It's something to do with adding the shadowJar task, because when I remove it, I can call Minecraft.getInstance(), but I can't get to the classes I need to shadow.

[[1.13.2] Minecraft.getInstance() method not found]

The mod I'm updating to 1.13.2 compiles but throws NoSuchMethodError on the first call to Minecraft.getInstance().

 

java.lang.NoSuchMethodError: net.minecraft.client.Minecraft.getInstance()Lnet/minecraft/client/Minecraft;

 

I'm running the mod using release 1.13.2-forge-25.0.50.

 

I'm assuming this is a build issue. My build.gradle is:

buildscript {
    repositories {
        maven { url = 'https://files.minecraftforge.net/maven' }
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '3.+', changing: true
        classpath 'com.github.jengelman.gradle.plugins:shadow:4.0.4'
    }
}

apply plugin: 'net.minecraftforge.gradle'
apply plugin: 'com.github.johnrengelman.shadow'

version = "1.13-2-25.0.50"
group = "com.shiny.joypadmod"

sourceCompatibility = targetCompatibility = compileJava.sourceCompatibility = compileJava.targetCompatibility = '1.8' // Need this here so eclipse task generates correctly.


allprojects {
        repositories {
            jcenter()
            maven { url "https://jitpack.io" }
        }
   }

tasks.build.dependsOn shadowJar

I tried adding reobf to the shadow jar, but the build then fails with a mapping error: "No value has been specified for property 'mappings'." The reobf tasks are as follows:

reobf {
	shadowJar {}
}
tasks.build.dependsOn reobfShadowJar

If you want to, you can create a script and then a bunch of desktop shortcuts that can allow you to switch between mod directories easily.

 

If you copy the copy below into a file called switchmc.bat and replace YOUR_USER_NAME with your computer's account name, then you can make desktop shortcuts to this file and add the mane of the mods directory to the target property.

 

E.g. if you save switchmc.bat into C:\ then create a shortcut called swichmc 1.8.9, right click, and then change the target to say C:\switchmc.bat 1.8.9

 

Now you can put all your 1.8.9  mods in a directory called mods_1.8.9 (in your .minecraft directory). 

 

It makes it faster to switch between versions of Minecraft. You still need to install forge for each version of minecraft and make a profile for each version.

 

Let me know if you need any help.
