POM padre non risolvibile per Impossibile trovare artefatto e 'parent.relativePath' punti a POM locale errato

Question

Sono nuovo per Maven.

Ho un progetto che cerco di creare con il maven3.

Quando si esegue il comando mvn -X clean install ho ricevuto l'errore.

[root@localhost]# mvn -X clean install

ho controllare la pom.xml ma riesco a capire quale fosse il problema. Alcune linee del mio pom.xml sono le seguenti.

1 <?xml version="1.0"?> 
    2 <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"

ho anche controllare la soluzione su qualche domanda a StackOverflow come Non-resolvable parent POM: Could not find artifact ma aiuto couldnt per risolvere il problema.

Se avete bisogno di ulteriori informazioni relative a questa domanda, fatemelo sapere.

Answer 1

È necessario avere il file /root/test/devenv/openstack-rhel/pom.xml

Questo file necessità di avere gli elementi seguenti:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 
    <modelVersion>4.0.0</modelVersion> 
    <groupId>org.openstack</groupId> 
    <artifactId>openstack-rhel-rpms</artifactId> 
    <version>2012.1-SNAPSHOT</version> 
    <packaging>pom</packaging> 
</project> 

Answer 2

Ho affrontato lo stesso problema. L'impostazione del percorso relativo del genitore nei progetti del modulo ha risolto il problema.

Usa <relativePath>../Parent Project Name/pom.xml</relativePath>

Answer 3

Abbiamo avuto lo stesso problema.

Il file principale pom era disponibile nel nostro repository locale, ma Maven ancora senza successo ha provato a scaricarlo dal repository centrale, oppure dalla relativePath (non c'erano file nel percorso relativo).

Si è verificato un file denominato "_remote.repositories" nel repository locale, causa di questo comportamento. Dopo aver eliminato tutti i file con questo nome dall'archivio locale completo, potremmo costruire i nostri moduli.
