Building and packaging projects with Maven
Building and packaging projects with Maven is one of its key features, which allows you to compile, test, and package your code into distributable artifacts, such as JAR or WAR files. Here's an overview of how to build and package a project with Maven:
Compile the code: Maven automatically compiles your source code when you run the "mvn compile" command. The compiled classes are stored in the target/classes directory.
Run tests: Maven also makes it easy to run your tests with the "mvn test" command. Maven uses a testing framework, such as JUnit, to execute your test cases and report any failures.
Package the project: Once the code is compiled and the tests have passed, you can create a distributable artifact using the "mvn package" command. This will create a JAR or WAR file in the target directory, which contains the compiled code, along with any required resources, such as configuration files or static assets.
For example, let's say you have a Java project with a main class in the "com.example.myapp" package. To build and package the project, you would run the following commands:
mvn compile # Compiles the source code
mvn test # Runs the tests
mvn package # Creates a JAR file in the target directory
The resulting JAR file can be distributed and run on any machine that has Java installed. By default, Maven also includes any dependencies your project requires in the JAR file, making it self-contained and easy to deploy.
Overall, building and packaging a project with Maven involves compiling the source code, running tests, and creating a distributable artifact using the "mvn package" command.
