maven-publish missing artifact to repository - kotlin

Question

II'm trying to publish my lib but i'm having some problems related to its publication.
I'm using this library https://github.com/vanniktech/gradle-maven-publish-plugin to publish my project on maven central (oss), but, this for some reason only -sources.jar, -javadoc.jar and .module are being pushed to the repository, however file-butler-0.1.4-SNAPSHOT.jar is missing :(
Does someone have any idea?
build.gradle(module)
plugins {
id 'java-library'
id 'kotlin'
id 'kotlin-kapt'
}
dependencies {
def gson = "com.google.code.gson:gson:2.8.6"
def moshi = "com.squareup.moshi:moshi:1.11.0"
def moshCodeGen = "com.squareup.moshi:moshi-kotlin-codegen:1.11.0"
implementation(Deps.core.kotlin)
implementation(gson)
implementation(moshi)
kapt(moshCodeGen)
testImplementation(Deps.testing.truth)
testImplementation(Deps.testing.jUnit)
kaptTest(moshCodeGen)
}
sourceSets {
main.kotlin.srcDirs += 'src/main/kotlin'
main.java.srcDirs += 'src/main/java'
}
apply plugin: "com.vanniktech.maven.publish"
build.gradle.kts(project)
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
mavenCentral()
google()
jcenter()
}
dependencies {
classpath("com.android.tools.build:gradle:4.1.0")
classpath(kotlin("gradle-plugin", "1.4.10"))
classpath("org.jetbrains.dokka:dokka-gradle-plugin:1.4.10")
classpath("com.vanniktech:gradle-maven-publish-plugin:0.13.0")
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
mavenCentral()
google()
jcenter()
}
}
task<Delete>("clean") {
delete(rootProject.buildDir)
}
ps: publishToMavenLocal publish the expected jar to my local repository.
