pom.xml is the main element of our project. In file are defined all of the dependencies for example:

• a way of building a project
• testing
• running a project
• generating documentation
• creating a release

After generating project pom.xml file looks as follows:

It looks very raw. Only groupId, artifactId, modelVersion, version. This information on this step is not very important for us. First, change that we will make will be adding JUnit library.

Now we can compile our project:

As we can see project build successfully. For now, we should look at three commands:

• mvn – this command runs maven and proper pom.xml file
• clean – delete target catalog and old files version
• compile – runs java compiler
