Dependent Mod not installing

[Echo343]

I need some help. I have two mods I made: blargsworkshop and horsepocket. Horsepocket depends on blargsworkshop. I've moved the jar from blargsworkshop into the libs folder in horsepocket and adjusted horsepocket build.gradle. Everything builds great, but after Forge loads from `runClient` I get an error in the minecraft gui saying that blargsworkshop is not installed.  What am I missing?  I've included both gradles.

You didn't specify a dependency configuration for the dependency

I'm going to need a better clue than that. I thought fg.deobf was the configuration we are suppose to use for our own mods as dependency. I've also tried other combinations such as compile, deobf, and similar ones as show as the examples in the mdk, but none of those even built successfully. Fg.deobf was the only one where everything built correctly.

[DaemonUmbra]

fg.deobf() is essentially a transformer or preprocessor for the dep

Well, that explains a bit more. Unfortunately, I've had no success at getting my mod to compile while trying any dependency configuration shown as an example in the mdk. I'm at such a loss for this. Does anyone have an example of what I'm trying to do?

There are many examples out there actually. Why don't you just look at other existing mods that depends on other mods to be installed? Look at the abnormals mods for example, which all requires Abnormals Core. See if you can find something useful in thei gradle setups

I finally figured it out. It was a combination of two things that were keeping me from the solution. First, I made a dumb mistake that took forever to track down. I just happened across a post that mentioned it. And two, knowledge. I know Java, but I am very new to gradle. Thanks to everyone you chimed in and provided tidbits of knowledge and pointers for me to research, learn, and seek after. I now have a better working understanding of how to read gradle.build files.

 

Ok, back to the first piece. Everywhere I looked, everyone and everything was telling me to put my mods in the 'libs' folder for forge to pick them up in a dev environment. I thought this meant 'build/libs'. Dumb mistake, but what everyone was talking about was a 'libs' folder that you have to create (if not there) at the root level (same level as build.gradle file). Once I corrected this, things started to flow.

 

Second, here is a copy of my working build.gradle file:
 

buildscript {
    repositories {
        maven { url = 'https://files.minecraftforge.net/maven' }
        jcenter()
        mavenCentral()

    dependencies {
        classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '3.+', changing: true
    }
}
apply plugin: 'net.minecraftforge.gradle'
// Only edit below this line, the above code adds and enables the necessary things for Forge to be setup.
apply plugin: 'eclipse'
apply plugin: 'maven-publish'

version = '1.0'
group = 'com.blargsworkshop.horsepocket' // http://maven.apache.org/guides/mini/guide-naming-conventions.html
archivesBaseName = 'Horse Pocket-1.16.1'

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

println('Java: ' + System.getProperty('java.version') + ' JVM: ' + System.getProperty('java.vm.version') + '(' + System.getProperty('java.vendor') + ') Arch: ' + System.getProperty('os.arch'))
minecraft {
    // The mappings can be changed at any time, and must be in the following format.

            mods {
                horsepocket {

            // Recommended logging level for the console
            property 'forge.logging.console.level', 'debug'

            mods {
                horsepocket {
                    source sourceSets.main
                }
            }
        }

        data {

            args '--mod', 'horsepocket', '--all', '--output', file('src/generated/resources/')

            mods {
                horsepocket {
                    source sourceSets.main
                }
            }
        }
    }
}

repositories {
  	flatDir {
        dirs 'libs' 
	}
}

dependencies {
    // Specify the version of Minecraft to use, If this is any group other then 'net.minecraft' it is assumed
    // that the dep is a ForgeGradle 'patcher' dependency. And it's patches will be applied.

jar {

            "Specification-Vendor": "horsepocketsareus",
            "Specification-Version": "1", // We are version 1 of ourselves
            "Implementation-Title": project.name,
            "Implementation-Version": "${version}",
            "Implementation-Vendor" :"horsepocketsareus",
            "Implementation-Timestamp": new Date().format("yyyy-MM-dd'T'HH:mm:ssZ")
        ])
    }
}

// Example configuration to allow publishing using the maven-publish task
// This is the preferred method to reobfuscate your jar file
jar.finalizedBy('reobfJar') 
// However if you are in a multi-project build, dev time needs unobfed jar files, so you can delay the obfuscation until publishing by doing
//publish.dependsOn('reobfJar')

publishing {
    publications {
        mavenJava(MavenPublication) {
            artifact jar
        }
    }
    repositories {
        maven {
            url "file:///${project.projectDir}/mcmodsrepo"
        }
    }
}

 

The parts I added/changed to make it work.
 

repositories {
  	flatDir {
        dirs 'libs' 
	}
}

This piece turns the new 'libs' folder I created into a repository so I can reference jars inside the folder in the dependency area which is the next change.

 

dependencies {
    // ...

    implementation fg.deobf("com.blargsworkshop.common:Blargs Workshop-1.16.1-1.0:1.0")
}

I added the implementation line into the dependency area. As far as I can tell here is the breakdown I learned:

• implementation -- means about the same as using the compile keyword which tells gradle to compile this dependency into the build.
• fg.deobf -- is a method provided by ForgeGradle that transforms the jar from the obfuscated form into the obfuscated form. I'm not really clear about this so don't quote me. But in essence this dependency is a forge mod that I made myself.
• com.blargsworkshop.common -- This syntax is part of the "maven coordinates" structure (google it!). This first piece is actually not needed in that it can be anything. When pulling from the flatDir { } repository, this first piece of the coordinate gets ignored.
• Blargs Workshop-1.16.1-1.0 -- This piece is the name of the Jar file (aka artifact) (originally, I was leaving off the '-1.0' since that was the version, but don't do that.)
• 1.0 -- This last piece is the version. Also specified up higher in the gradle.build (of the dependency mod!)

With all these piece in place I got my mod building and both mods installed and running when I run 'gradlew runClient'. Again, thanks for all those that helped and provided clues along the way. I hope this post breaks a few concepts down and makes it easy for newcomers learning gradle as well.

Update: With the above setup I was able to compile and run the code; however, when methods were called in the library mod (blargsworkshop) the game would crash with an error about not being able to find a method called something like, 'func_1234a'. I was under the assumption that the call to fg.deobf() was going to solve this issue, but I think my understanding of it is incomplete.

 

For now, I've solved my issue by commenting out the line.

// jar.finalizedBy('reobfJar')

in the build.gradle of my library mod as well as removing the call to fg.deobf(). Now that line looks like the following

implementation "com.blargsworkshop.common:Blargs Workshop-1.16.1-1.0:1.0"

I can now build and run my mods through my dev environment with 'runClient'. I will have to remember to recompile my library mod with 'reobfJar' enabled before I publish.
