Okay, so I have completed updating my forge mod to 1.7.2 and it works in the testing environment exactly how I want it to; however, when I after I built it using gradle when I run it in Minecraft a window comes up for a second closes and I get the following error:

I am both developing and running my Mod in forge build 10.12.0.1034.

 

I do not understand how in the exact same build of Forge the mod runs fine in Eclipse but doesn't work in Minecraft. This is very fustrating because I was planning on releasing an update to my mod today. Any help would be greatly appreciated.

Well I hate to bump the thread but I really wanted to release this mod tonight.

I built it by running the "gradlew build" command in command prompt and I got the jar file from the "libs" folder inside of "build".

Yeah I followed a tutorial and they told me to modify the version, group, & archivesBaseName fields. Below is what my build.gradle file looks like:

 

buildscript {

    repositories {

        mavenCentral()

        maven {

            name = "forge"

            url = "http://files.minecraftforge.net/maven"

        }

        maven {

            name = "sonatype"

            url = "https://oss.sonatype.org/content/repositories/snapshots/"

        }

    }

    dependencies {

        classpath 'net.minecraftforge.gradle:ForgeGradle:1.1-SNAPSHOT'

    }

}


apply plugin: 'forge'


version = "1.7.2-0.1.2"

group= "net.richardsprojects" // http://maven.apache.org/guides/mini/guide-naming-conventions.html

archivesBaseName = "RecipeExpansionPack"


minecraft {

    version = "1.7.2-10.12.0.1024"

    assetDir = "eclipse/assets"

}

processResources

{

    // replace stuff in mcmod.info, nothing else

    from(sourceSets.main.resources.srcDirs) {

        include 'mcmod.info'

                

        // replace version and mcversion

        expand 'version':project.version, 'mcversion':project.minecraft.version

    }

        

    // copy everything else, thats not the mcmod.info

    from(sourceSets.main.resources.srcDirs) {

        exclude 'mcmod.info'

    }

}[/Code]

Forge gradle / Minecraft don't seem to get along all the time; when I've had similar exceptions, I was able to get it working by running the gradle commands with "--refresh-dependencies", for example "gradlew --refresh-dependencies eclipse" will refresh all of the class paths etc. If you run through setting up the workspace with refresh dependencies on all the commands and it still doesn't work, maybe try updating to a later version of Forge as sometimes it gets broken.

In 1.7.2, setUnlocalizedName() is now called setBlockName() if i recall correctly.

Blocks - .setBlockName("PutStuffHere")

Items - .setUnlocalizedName("PutStuffHere");
