Maven-publish plugin could not upload in parallel

Old Forum Archive Bugs

We are using gradle from another build tool to publish artifacts to artifactory by using the maven-publish plugin.
When calling many gradle instances in parallel they seem to override each other pom/jar and tries to publish some jar/pom multiple times and some jar/pom not at all.
It only seems to happen when the groupName matches for the pom/jar.

Simple configuration to reproduce:

apply plugin: 'java'
apply plugin: 'maven-publish'

    publishing {
            publications {
                mavenJava(MavenPublication) {
                    groupId groupName
                    artifact file(artifactFilePath)
                    artifactId artifactName
                    version '001'
                }}}

Script that executes gradle in parallel 9 times with 3 different groupNames.

#!/bin/bash
TOP=3

for ((i=1; i<=$TOP; i++))
do
   for ((j=1; j<=$TOP; j++))
     do
        eval './gradlew publish -PartifactFilePath=empty.file -PgroupName=ciTest.subdir${i} -PartifactName=artifact${j}.file  -s &'
   done
done

I have tried the following flags without any luck:

-Dorg.gradle.daemon=false -Dorg.gradle.configureondemand=false -Dorg.gradle.parallel=false --project-cache-dir=/tmp/gradleCache/cache${i}${j}

One thing that helps is --recompile-scripts but that in turns makes the gradle publishing serial so I don’t know if it really fixes the issue or not.
