Open IDE and create file `Main.java` with the following content
```
public class Main {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
```
Use terminal to compile and execute
```
cd /home/project
javac Main.java
java Main
```
## Maven
Maven helps with:
- Making the build process easy
- Providing a uniform build system
- Providing quality project information
- Encouraging better development practices
Check Maven version in terminal
```
mvn -v
```
Build Java code
```
cp -r /home/abc/example /home/project/example
cd /home/project/example
mvn compile
```
This will run Maven, telling it to execute the compile goal. When it’s finished, you should find the compiled .class files in the target/classes directory.
Run the package goal
```
mvn package
```
To execute the JAR file run
```
java -jar target/gs-maven-0.1.0.jar
```
