Vanilla Java Maven Command Line Project
This repository shows a basic setup for a command line application in Java build with Maven.
Java 1.8 and Maven are expected to be installed on our system.
After cloning this repository, change into the newly created directory and run
This will install all dependencies needed for the project as well as compile all source files into an executable JAR file.
Running the Tests
All tests can be run by executing
mvn will automatically find all tests inside the
src/test directory and run them.
The test for class
Example is only verifying the return value of one method.
App on the other hand is tested via a test-double that gets injected.
This allows us to spy on the output of it.
We want to avoid printing anything to the screen while running the tests.
Injecting a test double in this instance is a nice way to isolate our application from the command line.
In the actual
Main class we then inject
System.out, which is Java's standard output stream.
Running the Application
mvn package the resulting JAR file is located in directory
The application can now be run by executing
java -jar target/java-maven-command-line-1.0-SNAPSHOT.jar
