How can I build WAR with Maven in Eclipse?

java, maven-2, web-applications

Solution

Actually, your POM looks a bit weird:

- it is missing the right `packaging` for a webapp project.

- the maven war plugin configuration doesn't look right, you just don't need the extra stuff you added.

Here is what a minimal pom looks like:

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mycompany.app</groupId>
  <artifactId>my-webapp</artifactId>
  <packaging>war</packaging>
  <version>1.0-SNAPSHOT</version>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <finalName>my-webapp</finalName>
  </build>
</project>

So either modify it and update the project configuration (right-click on your project then Maven > Update Project Configuration).

Or just start over and create your project using the `maven-archetype-webapp`. You can do this from Eclipse: New > Project... > Maven Project, then select the maven-archetype-webapp in the wizzard and follow the seps.

Or from the command line:

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-webapp -DarchetypeArtifactId=maven-archetype-webapp

Problem

I have project that I'm now starting as Maven project, but for some reason it is not working. Here is my pom.xml: ``` <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"> <modelVersion>4.0.0</modelVersion> <groupId>ProgramName</groupId> <artifactId>ProgramName</artifactId> <version>0.0.1-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>org.springframework.core</artifactId> <version>3.0.2.RELEASE</version> </dependency> <!-- all other dependecies here --> </dependencies> <build> <finalName>ProgramName</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.0.2</version> <configuration> <webResources> <resource> <targetPath>WEB-INF</targetPath> <directory>src/main/webapp/WEB-INF</directory> <filtering>true</filtering> <includes> <include>*.xml</include> </includes> </resource> </webResources> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.1</version> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-release-plugin</artifactId> <version>2.0</version> </plugin> </plugins> </build> </project> ```
