java - specifying goal in pom.xml

Question

I am creating a new maven project with pom.xml as below:-

<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>firstRestlet</groupId>
  <artifactId>restlet1</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>war</packaging>

  <name>restlet1</name>
  <url>http://maven.apache.org</url>
  <repositories>
<repository>
   <id>maven-restlet</id>
   <name>Public online Restlet repository</name>
   <url>http://maven.restlet.org</url>
</repository> 
</repositories>
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
</project>

The problem which i am facing is that target war file is not getting generated. On eclipse console after i ran this pom.xml what i found was goals missing in pom.xml.

ECLIPSE CONSOLE MESSAGE:

Please tell me how to specify goals in pom.xml.

Also tell me how to create RESTLET project using maven as build tool.

Thanks & Regards,

The error message which you specified is nothing but you are not specifying goal for maven build.

you can specify any goal in your run configuration for maven build like clear, compile, install, package.

please following below step to resolve it.

1. right click on your project.
2. click 'Run as' and select 'Maven Build'
3. edit Configuration window will open. write any goal but your problem specific write 'package' in Goal text box.
4. click on 'Run'
