Compiling a Maven project was pretty darn easy. You simply run the command mvn compile. This command tells maven to compile the source code into classes. The classes end up in the target/classes dir and target/test-classes dir.

Running mvn package will build a jar of the project. The version used in the jar name is contained inside the main level pom.xml.

pom.xml

   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
4.0.0
com.mattconroy.project
TestProject
jar   1.0-SNAPSHOT
TestProject
http://maven.apache.org


junit
junit
3.8.1
test

Notice the tag sets the jar version name.

So what does this buy us? We can now install our built component into a local or remote respository for use in other projects or run the program to do some business logic. Obviously we are far from having a complete product since we are missing libraries and other meta data needed to have a easily maintainable project, but this gives us a template to build off of.

Well, I am finally taking the plunge into Apache Maven. I have found that managing dependencies is becoming unbearable and Maven is being used by several open source project that I use so… Here I go, one step at a time.

My first question was obvious: How do I create a new Maven project?

After a few minutes of searching I ended up on the Maven website reading the ‘Getting Started‘ faq and found the very cryptic command on starting a project.

mvn archetype:create -DgroupId=com.mattconroy.project -DartificatId=TestProject

After running the above command I ended up with a directory structure that is suppose to magically work to build and maintain a project. Well, we’ll see.

The structure of the project:

TestProject
- pom.xml
- src
- main
- java
- com/mattconroy/project
- App.java
- test
- java
- com/mattconroy/project
- AppTest.java

So this makes sense… One directory for program code and another for program unit tests. I can live with this.

A friend of mine finds things like this all the time. Watch this silent movie. Very witty!

This is the source code for a quick color matching game I wrote for fun.
It is very rough, but does demonstrate some examples of using full screen windows.
