How can I build WAR with Maven in Eclipse?

Question

I have project that I\'m now starting as Maven project, but for some reason it is not working. Here is my pom.xml:

Answer 1

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

Answer 2

I suggest use m2eclipse. It's a one click operation using the Eclipse plugin.

Answer 3

for instance, I see

<packaging>war</packaging>

missing in your pom, you should have a look at how the maven-war-plugin is used.
