Upload an existing collection of 3rd-party Jars to a Maven server in Gradle?

build.gradle

apply plugin:'java'
apply plugin:'maven'

import org.gradle.api.internal.artifacts.publish.DefaultPublishArtifact

version = "6.1.1"
group = "com.oahu" 

ant.importBuild "$projectDir/tools/ant/package.xml" 

// a list of the ant tasks that create a jar
// I assumed the following convention:
// ant task named "SampleAntJar-jar" creates the jar  "build/SampleAntJar.jar" 
def antJarTasks = ["SampleAntJar-jar", "SecondSampleAntJar-jar"]

artifacts{
    //for each ant task add a defaultpublishArtifact to the archives configuration
    antJarTasks.each{ taskName ->
        def artifactName = taskName - '-jar'
        archives new DefaultPublishArtifact(artifactName, "jar", "jar", null, new            
                       Date(), new File("$buildDir", "${artifactName}.jar"))    
    }
}

uploadArchives(){
    dependsOn: antJarTasks 
    repositories {
        mavenDeployer {
            repository(url: "file://{'/Users/Rene/.m2/repository/'}")
            antJarTasks.each{ antJarTask ->
                antJarName = antJarTask - "-jar"
                addFilter(antJarName) {artifact, file ->
