Hello,

I am trying to use Patchouli so I can make a book in my mod.

I copied the part I think I need from Botania's build-gradle.
https://github.com/VazkiiMods/Botania/blob/fb8d7db61c54930d29f4b22ab988a783d61c83da/Common/build.gradle
https://github.com/VazkiiMods/Botania/blob/4697930092cd1cc1ad318abc9ab7ebf58ee9b5ce/Forge/build.gradle

But the compilation fails with the following error:

A problem occurred evaluating root project 'test_mod'.
> Could not find method compileOnly() for arguments [vazkii.patchouli:Patchouli-xplat:1.18.2-66-SNAPSHOT] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

Where does compileOnly() come from?

This is my build.gradle:

buildscript {
    repositories {
        maven { url = 'https://maven.minecraftforge.net' }

        maven {
            name = "Jared"
            url = "https://maven.blamejared.com/"
        }

        mavenCentral()
    }
    
    dependencies {
        classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '5.1.+', changing: true

        compileOnly "vazkii.patchouli:Patchouli-xplat:1.18.2-66-SNAPSHOT"
        implementation fg.deobf("vazkii.patchouli:Patchouli:1.18.2-66-SNAPSHOT")
    }
}

apply plugin: 'net.minecraftforge.gradle'
apply plugin: 'eclipse'
apply plugin: 'maven-publish'

version = '1.0'
group = 'com.ideki.test_mod'
archivesBaseName = 'test_mod'

java.toolchain.languageVersion = JavaLanguageVersion.of(17)

println('Java: ' + System.getProperty('java.version') + ' JVM: ' + System.getProperty('java.vm.version') + '(' + System.getProperty('java.vendor') + ') Arch: ' + System.getProperty('os.arch'))
minecraft {
    mappings channel: 'official', version: '1.18.1'

    accessTransformer = file('src/main/resources/META-INF/accesstransformer.cfg')
    
    runs {
        client {
            workingDirectory project.file('run')

            mods {
                test_mod {
                    source sourceSets.main
                }
            }
        }

        server {
            workingDirectory project.file('run')

            mods {
                test_mod {
                    source sourceSets.main
                }
            }
        }

        data {
            workingDirectory project.file('run')

            args '--mod', archivesBaseName, '--all', '--output', file('src/generated/resources/'), '--existing', file('src/main/resources/')

            mods {
                test_mod {
                    source sourceSets.main
                }
            }
        }
    }
}

sourceSets.main.resources { srcDir 'src/generated/resources' }

repositories {
}

dependencies {
    minecraft 'net.minecraftforge:forge:1.18.1-39.0.5'
}

jar {
    manifest {
        attributes([
                "Specification-Title"     : "test_mod",
                "Specification-Vendor"    : "Ideki",
                "Specification-Version"   : "1",
                "Implementation-Title"    : project.name,
                "Implementation-Version"  : project.jar.archiveVersion,
                "Implementation-Vendor"   : "Ideki",
                "Implementation-Timestamp": new Date().format("yyyy-MM-dd'T'HH:mm:ssZ")
        ])
    }
}

jar.finalizedBy('reobfJar')

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

Ok, so I fixed my build.gradle
Then I was able to compile.
But minecraft started I got an error message from Patchouli that basically said that I was not using the correct version of Forge.
So I changed the dependency to

Quote

minecraft 'net.minecraftforge:forge:1.18.1-39.1.0'

And I downloaded forge-1.18.1-39.1.0-mdk.zip

I extracted the files and copied gradlew, gradlew.bat and the gradle folder to my mod folder.

Now when I try to compile I get the following error:

Quote

Exception in thread "main" java.lang.IllegalStateException: Could not find forge-1.18.1-39.0.5 in classpath

So I am guessing I did something wrong when attempting to update the forge mdk.

Any idea what I am missing ?

nvm, just realized that patchouli is using MC 1.18.2
So I got the wrong MDK
