org.apache.maven.plugins लक्ष्य निष्पादन के विफल

Question

मैं Maven का उपयोग कर एक युद्ध फ़ाइल उत्पन्न करने के लिए कोशिश कर रहा हूँ, लेकिन मैं इस त्रुटि हो रही है (लॉग उत्पादन को डाउनलोड करने का सबसे अधिक स्पष्ट लॉग ऑन करने के लिए छोड़ दिया जाता है):

<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/maven- 
v4_0_0.xsd">

     <scope>test</scope> 
    </dependency> 
    </dependencies> 

    <build> 
    <finalName>tn.talan.selenium</finalName> 

    <plugins> 
     <plugin> 
     <groupId>org.apache.maven.plugins</groupId> 
     <artifactId>maven-war-plugin</artifactId> 
     </plugin>

     <artifactId>tomcat-maven-plugin</artifactId> 
     <version>1.0-beta-1</version> 
     </plugin> 

    </plugins> 

    </build> 

</project> 

क्या मेरी पोम साथ कुछ गड़बड़ है:

maven-war-plugin के लिए संस्करण निर्दिष्ट करें, उदा।

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-war-plugin</artifactId> 
    <version>2.2</version> 
</plugin>
