A Minimalistic POM For JavaEE 6/7
The essential pom for JavaEE projects is < 40 lines of 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/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.airhacks</groupId>
<artifactId>javaee-essentials-pom</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging>
<dependencies>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>6.0</version>
<scope>provided</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
</project>
The war plugin has only has to be added to make web.xml
optional :-). If you need a web.xml (for JAX-RS or Servlets web.xml is not needed), you can remove the war plugin as well.
The pom.xml was also checked-in into: https://github.com/AdamBien/javaee-essentials-pom
If you are planning to write tests (:-)), you should replace the javaee-web-api
dependency with an actual server implementation.
See you at Java EE Workshops at MUC Airport (Maven is discussed in the "Effective JavaEE" workshop)!
Hello Adam,
Has the crippled APIs problem you mentioned in a previous article (http://www.adam-bien.com/roller/abien/entry/trouble_with_crippled_java_ee) been resolved?

@Gerald,
no. It is going to be resolved in JavaEE 7. For JavaEE 6 you will have to choose an application server. I'm going to add a note to this post.
Thanks for reminding me!,

This is for Java EE 6 and will not work for Java EE 7 ?

What would the minimum pom file look like if you need to create an ear file (needed for WebSphere)?

@Arun,
it would work with JavaEE7. However, there is no a Maven JavaEE7 dependency yet deployed to Maven central. You would have to use the dependency from java.net now. I guess it is going to be resolved after JavaEE 7 is finalized.
thanks for the comment,
adam

@Craig,
I never used EARs in JavaEE6 projects again. I think the last time I did it in ~2010.
Use NetBeans Maven / Ear wizard or e.g. org.codehaus.mojo.archetypes:ear-javaee6 to get the first idea.
Usually you can delete a lot of stuff afterwards (what I did for WAR projects),
thanks!,

To further shorten the POM you could replace the plugin declarations with only the properties:
<properties>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
<failOnMissingWebXml>false</failOnMissingWebXml>
</properties>
