Impossibile trasferire artefatto pom in gradle maven-publish plug-in

Question

Uso il gradle (2.9) plug-in maven-publish per pubblicare un file in un repository privato nexus maven. Il file è build.gradle

apply plugin: 'maven-publish' 

publishing { 
    repositories { 
     maven { 
      name "example-maven" 
      url "https://..." 
      credentials { 
       username mavenUser 
       password mavenPassword 
      } 
     } 
    } 
    publications { 
     maven(MavenPublication) { 

      groupId 'com.example.karaf-utils' 
      artifactId 'esa-bootstrapper' 
      version '1.0.0' 

      artifact source: "${projectDir}/kar/example.esa.bootstrapper.kar", extension: 'kar' 

     } 
    } 
} 

il file kar sia correttamente caricato e in nesso posso vedere il descrittore XML atteso:

<dependency> 
    <groupId>com.example.karaf-utils</groupId> 
    <artifactId>esa-bootstrapper</artifactId> 
    <version>1.0.0</version> 
    <type>kar</type> 
</dependency> 

ma purtroppo, durante l'esecuzione del compito publish, ottengo il seguente errore:

Come posso risolvere questo errore?

Answer 1

Problema risolto: il punto è che stavo cercando di sovrascrivere un file pom esistente in nexus. Ho cancellato il file kar ma ho dimenticato di rimuovere il pom prima di eseguire il compito gradle.
