pom.xml Datei ist nicht richtig konfiguriert

Question

Ich habe einige Probleme mit der Datei pom.xml. Ich habe versucht, die ganze Lösung über das Internet gefunden, aber niemand hat mir geholfen. Ich würde es sehr schätzen, wenn Sie mir helfen könnten. Unten finden Sie meine pom.xml-Datei und das Fehlerprotokoll.

Vielen Dank im Voraus!

Answer 1

Sie sollten Elternartefakt hinzufügen.

<parent> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-parent</artifactId> 
    <version>1.4.2.RELEASE</version> 
</parent> 

ODER

Wenn Sie die Starter Eltern nicht verwenden, in Ihrem pom.xml müssen Sie (innen das Element):

<build> 
    <plugins> 
    <plugin> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-maven-plugin</artifactId> 
    <version>${spring-boot-version}</version> 
    </plugin> 
    <plugin> 
    <artifactId>maven-war-plugin</artifactId> 
    <configuration> 
     <failOnMissingWebXml>false</failOnMissingWebXml> 
    </configuration> 
</plugin> 
    </plugins> 
</build>
