Hello,

I have a multi-project gradle build, like bellow.

    +-- rootproject
    |   +-- subproject1
    |   |   +-- src
    |   |   \-- build.gradle (1)
    |   |   \-- settings.gradle (1)
    |   |
    |   +-- subproject2
    |   |   +-- src
    |   |   \-- build.gradle  (2)
    |   |   \-- settings.gradle  (2)
    |   |
    |   +-- subproject3
    |   |   +-- src
    |   |   \-- build.gradle  (3)
    |   |   \-- settings.gradle  (3)
    |   |
    |   \-- build.gradle  (root)
    |   \-- settings.gradle  (root)

In my root ‘build.gradle’ I have define a common way for maven publication:

subprojects {
    
    ...
    
    version = "1.0.0"    
    group = "com.society.division.department.component"
    
    ...
    
    // maven publication
    apply plugin: 'maven-publish'

    publishing {
        repositories {
            maven{
                credentials {
                    username "${own_artifactory_username}"
                    password "${own_artifactory_password}"
                }
                
                url "${own_artifactory_server}${own_artifactory_release_repository}"
            } 
        }
        publications {
            maven(MavenPublication) {
                artifact (jarApi){
                    artifactId "comp_${project.name}"
                    classifier "api"
                    extension 'jar'
                }
                artifact (project.tasks.jar){
                    artifactId "comp_${project.name}"
                    extension 'jar'
                }
                artifact (project.tasks.jarStub){
                    artifactId "comp_${project.name}"
                    classifier "stub"
                    extension 'jar'
                }
                artifact (project.tasks.jarTest){
                    artifactId "comp_${project.name}"
                    classifier "test"
                    extension 'jar'
                }
    
                pom.withXml {
                    asNode().appendNode('name', "${project.name}")
                    asNode().appendNode('description', "${description}")
                  }
            }
        }
    }
    
    ...
}

When i call gradle publish task, the publication work fine but the destination path is.

    +-- maven_repository
    |   +-- com
    |   |   +-- society
    |   |   |   +-- division
    |   |   |   |   +-- department
    |   |   |   |   |   +-- component
    |   |   |   |   |   |   +-- comp_subproject1
    |   |   |   |   |   |   |   +-- 1.0.0
    |   |   |   |   |   |   |      \-- comp_subproject1-1.0.0.jar
    |   |   |   |   |   |   |      \-- comp_subproject1-1.0.0-api.jar
    |   |   |   |   |   |   |      \-- comp_subproject1-1.0.0-stub.jar
    |   |   |   |   |   |   |      \-- comp_subproject1-1.0.0-test.jar
    |   |   |   |   |   |   |      \-- comp_subproject1-1.0.0.pom
    |   |   |   |   |   |   |
    |   |   |   |   |   |   +-- comp_subproject2
    |   |   |   |   |   |   |   +-- 1.0.0
    |   |   |   |   |   |   |      \-- comp_subproject2-1.0.0.jar
    |   |   |   |   |   |   |      \-- comp_subproject2-1.0.0-api.jar
    |   |   |   |   |   |   |      \-- comp_subproject2-1.0.0-stub.jar
    |   |   |   |   |   |   |      \-- comp_subproject2-1.0.0-test.jar
    |   |   |   |   |   |   |      \-- comp_subproject2-1.0.0.pom
    |   |   |   |   |   |   |
    |   |   |   |   |   |   +-- comp_subproject3
    |   |   |   |   |   |   |   +-- 1.0.0
    |   |   |   |   |   |   |      \-- comp_subproject3-1.0.0.jar
    |   |   |   |   |   |   |      \-- comp_subproject3-1.0.0-api.jar
    |   |   |   |   |   |   |      \-- comp_subproject3-1.0.0-stub.jar
    |   |   |   |   |   |   |      \-- comp_subproject3-1.0.0-test.jar
    |   |   |   |   |   |   |      \-- comp_subproject3-1.0.0.pom

But I would like to have something like that :

    +-- maven_repository
    |   +-- com
    |   |   +-- society
    |   |   |   +-- division
    |   |   |   |   +-- department
    |   |   |   |   |   +-- component
    |   |   |   |   |   |   +-- 1.0.0
    |   |   |   |   |   |   |    \-- comp_subproject1-1.0.0.jar
    |   |   |   |   |   |   |    \-- comp_subproject1-1.0.0-api.jar
    |   |   |   |   |   |   |    \-- comp_subproject1-1.0.0-stub.jar
    |   |   |   |   |   |   |    \-- comp_subproject1-1.0.0-test.jar
    |   |   |   |   |   |   |    \-- comp_subproject1-1.0.0.pom
    |   |   |   |   |   |   |    \-- comp_subproject2-1.0.0.jar
    |   |   |   |   |   |   |    \-- comp_subproject2-1.0.0-api.jar
    |   |   |   |   |   |   |    \-- comp_subproject2-1.0.0-stub.jar
    |   |   |   |   |   |   |    \-- comp_subproject2-1.0.0-test.jar
    |   |   |   |   |   |   |    \-- comp_subproject2-1.0.0.pom
    |   |   |   |   |   |   |    \-- comp_subproject3-1.0.0.jar
    |   |   |   |   |   |   |    \-- comp_subproject3-1.0.0-api.jar
    |   |   |   |   |   |   |    \-- comp_subproject3-1.0.0-stub.jar
    |   |   |   |   |   |   |    \-- comp_subproject3-1.0.0-test.jar
    |   |   |   |   |   |   |    \-- comp_subproject3-1.0.0.pom

How to change the maven publication layout ? to perform this ?

Thank you.

A Maven repository has a specific layout, which is part of repository’s “API”. I don’t think you can accomplish what you want using the maven-publish plugin.

I believe the ivy-publish plugin could allow you to specify such a custom layout, but I have no real experience with that plugin.

Thank’s for your answer … i will keep maven with this layout for the moment …
