ich habe die Datei folgende Kind Modul pom:

</dependency> 
</dependencies> 
</project> 

ich habe versucht, das zu kommentieren Unter Teil in der Eltern-Pom-Datei (ich weiß nicht, ob es richtig ist, es zu tun), dann ist dieser Fehler weg und der Build schlägt mit this Fehler fehl.

<parent> 
<groupId>com.topdesk</groupId> 
<artifactId>tis-parent</artifactId> 
<version>3.4</version> 
</parent> 

Bitte helfen Sie mir!

Dank

Answer 1

Die normale Layout für ein Maven-Multi-Modul-Projekt ist:

parent 
├── pom.xml 
├── module 
   ├── pom.xml 

Überprüfen Sie, ob Sie das Layout.

Zusätzlich:

1. die relativePath sieht seltsam aus. Statt '..'

   <relativePath>..</relativePath> 
   

   try '../' statt:

   <relativePath>../</relativePath> 
   

   können Sie auch relativePath entfernen, wenn Sie das Standardlayout verwenden. Dies ist, was ich immer tue, und auf der Kommandozeile kann ich auch das Eltern (und alle Module) oder nur ein einzelnes Modul erstellen.

2. Der Modulpfad ist möglicherweise falsch. In der übergeordneten definieren Sie das Modul als:

   <module>junitcategorizer.cutdetection</module> 
   

   Sie den Namen des Ordners des Kindes Modul, kein Artefakt Kennung angeben müssen. Wenn junitcategorizer.cutdetection nicht der Name des Ordners ist, ändern Sie ihn entsprechend.

Hoffnung, die ..

EDIT hilft haben einen Blick auf die anderen Post, ich dort beantwortet.

Answer 2

Sie mit der folgenden Art und Weise versuchen,

<parent> 
    <groupId></groupId> 
    <artifactId></artifactId> 
    <version></version> 
    </parent> 

Damit die Mutterglas aus dem Repository holen sein wird.
