Gradle Publish does not upload files to the Nexus repository (Maven 2)

Question

I’m trying to get my project to send the Jars files to a Nexus (Maven 2) repository but I’m not getting it. The project is programmed in Kotlin.

This code fragment is as close as I could get to a result:

plugins {
     id 'maven'
}

allprojects {
    uploadArchives {
        repositories {
            mavenDeployer {
                repository(url: "http://meusite.com/repository/meurepo-releases/") {
                    authentication(userName: variavelComUser, password: variavelComPass)
                }

                snapshotRepository(url: "http://meusite.com/repository/meurepo-snapshots/") {
                    authentication(userName: variavelComUser, password: variavelComPass)
                }
            }
        }
    }
}

When I execute the task publish this occurs:

20:02:07: Executing task 'uploadArchives'...

But when I access the Nexus I see nothing there, it’s still empty.

What I’m doing wrong or what’s missing?

The problem is that the block uploadArchives was not being applied to all projects as it seemed.

As my root project was just a container of other subprojects I solved in this way:

subprojects {
    afterEvaluate {
        if (it.plugins.hasPlugin('maven') ) {
            uploadArchives {
                repositories {
                    mavenDeployer {
                        repository(url: "http://meusite.com/repository/meurepo-releases/") {
                            authentication(userName: varComUser, password: varComSenha)
                        }

                        snapshotRepository(url: "http://meusite.com/repository/meurepo-snapshots/") {
                            authentication(userName: varComUser, password: varComSenha)
                        }
                    }
                }
            }
        }
    }
}

Watching we see 3 important changes:

1. I traded allprojects for subprojects since my root project has no source code.
2. I inserted the block afterEvaluate to run the block after the first settings are ready in all sub-modules.
3. I added a check if you have the plugin Maven before putting the uploadArchives and put applied the plugin in all modules I want to export to the Nexus, and with it I took the block id maven block plugins root module.

This way I managed to get each module sent to the Nexus individually.
