Run Main Class of Maven Project
Kickstart your Maven project by executing the main class:
Don't forget to replace com.example.Main
with your class's full path to get your project up and running.
Got arguments to pass? No problem!
Just change firstArg secondArg thirdArg
with your actual arguments.
Leveraging Maven-exec-plugin
The maven-exec-plugin, a handy tool for executing Java applications, can be tailor-fitted in your pom.xml or dispatched directly from the CLI like a skilled commando.
Profile Activation
Power up specific Maven profiles or bypass prompts with the -P
option. Like a secret handshake, it helps you gain exclusive access to your Main
class.
The Power of mvnexec
Finding the Main
class in a deeply nested project structure is like finding a needle in a haystack. The mvnexec
script automatically locates classes with Main
methods – it's like a compass directing you through your labyrinth-like project.
Faster Execution with -B
Shave off compilation time when not required with the -B
option or --batch-mode
flag. It's like hitting the turbo boost on your project execution!
Flexible Class Filtering
mvnexec
not only locates our Main
classes, but also allows you to filter based on scope (test/main) or name. Perfect for when you're dealing with larger projects and need a bit more control.
Insightful Execution Details
Pom.xml - Your Stage Setter
Adding the maven-exec-plugin
in your pom.xml provides a stable environment for class execution. Especially handy when working with a team or on a CI/CD pipeline.
Passing the Baton - Arguments
mvn exec:java
can pass arguments to your main method similar to a relay race. Use -Dexec.args
to ensure a smooth transition of your arguments.
Working with Multiple Main Methods
In case your project has multiple main methods, consider using naming conventions or Maven profiles to clearly select the appropriate class. This will help to avoid the "Oops! Wrong door" scenario.
