• Avoid posting the same question on multiple channels. One channel is enough, and if needed to repost to another channel, post the link to avoid duplication.

you are missing, what to publish. check the

from

part in https://docs.gradle.org/current/userguide/publishing_maven.html#ex-customizing-the-publication-identity

Vampire

Actually the opposite. You should remove your whole

publishing

block as it is pointless.

Vampire

04/07/2025, 8:07 PM

mavenLocal()

(which you should avoid to ever use whenever possible) is always available for publishing and never needs to be declared explicitly for publishing

til 1

Vampire

04/07/2025, 8:07 PM

And the

java-gradle-plugin

already registers the publications you need for your plugin for you, one for the code artifact and one for the marker artifact of each plugin.

Vampire

04/07/2025, 8:08 PM

So applying the

java-gradle-plugin

and

maven-publish

plugin is sufficient and your whole

publishing

block should go away.

Plugin - Build.gardle.kts:

Copy code

plugins {
    kotlin("jvm") version "1.9.24"
    `java-gradle-plugin`
    `maven-publish`
}

group = "dev.haas"
version = "1.0.0"

repositories {
    mavenCentral()
    gradlePluginPortal()
}

dependencies {
    implementation(kotlin("stdlib"))
    implementation("org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.24")
}

kotlin {
    jvmToolchain(17)
}

gradlePlugin {
    plugins {
        create("kotlinPlugin") {
            id = "dev.haas.kotlinplugin"
            implementationClass = "dev.haas.SourceInspectionPlugin"
        }
    }
}

Test- Build.gradle.kts:

Copy code

plugins {
    id("dev.haas.kotlinplugin") version "1.0.0"

~/Kotlin/untitled3 git:[main] ls ~/.m2/repository/dev/haas///kotlinplugin//dev.haas.kotlinplugin.gradle.plugin/1.0.0/ dev.haas.kotlinplugin.gradle.plugin-1.0.0.pom the contents of my plugin

I am using only maven publishing I have updated my build scirpt

Copy code

plugins {
    kotlin("jvm") version "1.9.24"
    `java-gradle-plugin`
    `maven-publish`
}

group = "dev.haas"
version = "1.0.0"

repositories {
    mavenCentral()
    gradlePluginPortal()
}

dependencies {
    implementation(kotlin("stdlib"))
    implementation("org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.24")
}

kotlin {
    jvmToolchain(17)
}

publishing {
    publications {
        create<MavenPublication>("maven") {
            groupId = "dev.haas"
            artifactId = "kotlingradleplugin"
            version = "2.0"

            from(components["java"])
        }
    }
}

with this when i publish i get two plugins created: ~/Kotlin/untitled3 git:[main] ls ~/.m2/repository/dev/haas/ kotlingradleplugin untitled3 but when i try to use it none of them work

Copy code

plugins {
    id("dev.haas.kotlingradleplugin") version "2.0"
} 
or
plugins {
    id("dev.haas.untitled3") version "1.0.0"
}

The error message is quite clear, isn't it?

Suhas Sharma

04/08/2025, 2:37 AM

sorry i dont understand

Vampire

04/08/2025, 2:39 AM

Searched in the following repositories:

Gradle Central Plugin Repository

You do not have Maven local as plugin repository

Suhas Sharma

04/08/2025, 2:39 AM

i am very much new to plugins

Suhas Sharma

04/08/2025, 2:39 AM

Copy code

plugins {
    id("dev.haas.untitled3") version "1.0.0"
}

group = "dev.haas"
version = "1.0-SNAPSHOT"

repositories {
    mavenLocal()
    gradlePluginPortal()
    mavenCentral()
}

dependencies {
    testImplementation(platform("org.junit:junit-bom:5.10.0"))
    testImplementation("org.junit.jupiter:junit-jupiter")
}

tasks.test {
    useJUnitPlatform()
}

my test project build file

Vampire

04/08/2025, 2:40 AM

So?

Suhas Sharma

04/08/2025, 2:40 AM

it has mavenlocal() configured in repositories right

Suhas Sharma

04/08/2025, 2:46 AM

can you please clone my plugin code publish it on your machine and check if it is working https://github.com/Suhas-Koheda/GSOCPlugin

Vampire

04/08/2025, 2:56 AM

No, it has maven local for dependencies, not for plugins

Vampire

04/08/2025, 2:56 AM

plugin repositories are declared in your settings script in the plugin management block

Vampire

04/08/2025, 2:57 AM

you see in the error message the list of repositories that was searched in

Vampire

04/08/2025, 2:57 AM

and that is only the plugin portal which is the sole default if you don't configure anything explicitly

Suhas Sharma

04/08/2025, 2:57 AM

ohh now i undertsand

Suhas Sharma

04/08/2025, 2:57 AM

how do i configure repository for plugins?

Vampire

04/08/2025, 2:58 AM

I just told you

Suhas Sharma

04/08/2025, 3:01 AM

it is searching for dev.haas.kotlingradleplugindev.haas.kotlingradleplugin.gradle.plugin2.0 while i have dev.haas.kotlingradleplugin:2.0

Vampire

04/08/2025, 6:47 AM

In your repo you still have a publishing block, but you should have none. And you published version 1.0.0 but try to consume 2.0

Suhas Sharma

04/08/2025, 10:16 AM

okay ive updated it

Copy code

plugins {
    kotlin("jvm") version "1.9.24"
    `java-gradle-plugin`
    `maven-publish`
}

group = "dev.haas"
version = "1.0.0"

repositories {
    mavenCentral()
    gradlePluginPortal()
}

dependencies {
    implementation(kotlin("stdlib"))
    implementation("org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.24")
}

kotlin {
    jvmToolchain(17)
}

my project name is untitled3 so i should refernece with dev.haas.untitled3 with version1.0.0

Copy code

id("dev.haas.untitled3") version "1.0.0"

Copy code

pluginManagement {
    repositories {
        mavenCentral()
        mavenLocal()
    }
}

added this to settings gradle still doesnt work Gradle Core Plugins (plugin is not in 'org.gradle' namespace) - Included Builds (No included builds contain this plugin) - Plugin Repositories (could not resolve plugin artifact 'dev.haas.untitled3dev.haas.untitled3.gradle.plugin1.0.0') Searched in the following repositories: MavenRepo MavenLocal(file:/home/suhas-koheda/.m2/repository/) at org.gradle.plugin.use.resolve.internal.PluginResolutionResult.getFound(PluginResolutionResult.java:112) at org.gradle.plugin.use.internal.DefaultPluginRequestApplicator.resolvePluginRequest(DefaultPluginRequestApplicator.java:192) at org.gradle.

I added to your settings file:

Copy code

pluginManagement {
    repositories {
        mavenCentral()
        gradlePluginPortal()
    }
}

and commented out the publishing block in your build file. And it worked fine when i published to maven local:

Vampire

04/08/2025, 8:39 PM

I said you should remove the

publishing

block. But you also now removed the

gradlePlugin

block. Without that, you do not have any plugin defined, so no marker artifact is published and hence no plugin to consume.
