Practical Java Programming for IoT, AI, and Blockchain

APPENDIX BApache Maven Tutorial

When you are developing a Java software project, there are many tasks to take care of: downloading dependencies, putting JAR files on a classpath, compiling source code into binary bytecode, running tests, packaging bytecode into deployable JAR files, deploying JAR files to a remote repository server, and so on. Apache Maven, a software project management and comprehension tool that is based on the concept of a project object model (POM), can automate all of these tasks. Maven is intended primarily as a tool for managing Java-based projects, but it can also be used for projects using other programming languages such as C# and Ruby. As alternatives to Maven, Ant and Gradle are also popular software project management tools.

For more information about Ant, see http://ant.apache.org/.

For more information about Gradle, see https://gradle.org/guides/#getting-started.

Downloading Maven

You can download Apache Maven as a zipped file, apache-maven-3.6.0-bin.zip, from the following address:

https://maven.apache.org/download.cgi

After downloading it, just unzip the file to a directory, for example, c:\apache-maven-3.6.0\. Once it is unzipped, you will find the Maven program, mvn.jar, in the bin subdirectory. To test your Maven, just run the following command:

mvn --version

But you need to add c:\apache-maven-3.6.0\bin\ to your system PATH first, or simply ...
