Hey, I’m working on a mod with Fabric Mc and I want to use Spring inside.
So to achieve that I have made this build.gradle config :
plugins {
id 'fabric-loom' version '0.11-SNAPSHOT'
id 'org.springframework.boot' version '2.5.4'
id 'io.spring.dependency-management' version '1.0.15.RELEASE'
}
sourceCompatibility = JavaVersion.VERSION_17
targetCompatibility = JavaVersion.VERSION_17
archivesBaseName = project.archives_base_name
version = project.mod_version
group = project.maven_group
repositories {
// Add repositories to retrieve artifacts from in here.
// You should only use this when depending on other mods because
// Loom adds the essential maven repositories to download Minecraft and libraries from automatically.
// See https://docs.gradle.org/current/userguide/declaring_repositories.html
// for more information about repositories.
maven { url 'https://jitpack.io' }
maven { url 'https://oss.sonatype.org/content/repositories/snapshots' }
maven { url 'https://mvnrepository.com/artifac' }
maven { url 'https://zoidberg.ukp.informatik.tu-darmstadt.de/artifactory/public-releases' }
maven { url 'https://maven.terraformersmc.com/releases' }
mavenCentral()
}
configurations {
springBom
compileOnly.extendsFrom(springBom)
annotationProcessor.extendsFrom(springBom)
implementation.extendsFrom(springBom)
all {
// We need to use fabric implementation of log4j
exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
}
}
dependencies {
// To change the versions see the gradle.properties file
minecraft "com.mojang:minecraft:${project.minecraft_version}"
mappings "net.fabricmc:yarn:${project.yarn_mappings}:v2"
modImplementation "net.fabricmc:fabric-loader:${project.loader_version}"
// Fabric API. This is technically optional, but you probably want it anyway.
modImplementation "net.fabricmc.fabric-api:fabric-api:${project.fabric_version}"
// Spring boot dependencies
springBom enforcedPlatform('org.springframework.boot:spring-boot-dependencies:2.5.4.RELEASE')
api include('org.springframework.boot:spring-boot-starter')
implementation include('org.springframework.boot:spring-boot-dependencies:2.5.4.RELEASE')
implementation include('org.springframework.boot:spring-boot-starter-web')
implementation include('org.springframework.boot:spring-boot-starter-websocket')
// OpenAPI swagger
implementation include('org.springdoc:springdoc-openapi-ui:1.6.13')
// Spring discord api
implementation include('com.discord4j:discord4j-core:3.2.3')
}
processResources {
inputs.property "version", project.version
filesMatching("fabric.mod.json") {
expand "version": project.version
}
}
tasks.withType(JavaCompile).configureEach {
it.options.release = 17
}
java {
// Loom will automatically attach sourcesJar to a RemapSourcesJar task and to the "build" task
// if it is present.
// If you remove this line, sources will not be generated.
withSourcesJar()
}
And it works while I run it with Gradle. But when I try to generate the jar, I don’t get transient dependency of spring and that result on this error when I run from the jar :
java.lang.RuntimeException: Could not execute entrypoint stage 'server' due to errors, provided by 'litopia_services'!
Caused by: java.lang.NoClassDefFoundError: org/springframework/boot/SpringApplication
at fr.litopia.services.LitopiaServices.onInitializeServer(LitopiaServices.java:23) ~[litopia-services-1.0.0.jar:?]
So, how can I correctly include the spring boot dependency inside my build jar?
