## Intro
To start, open Quickstart page [localhost:8020](http://localhost:8020/) for quick access to all the tools
From the quicklaunch page you can open workspace tools, such as code editor or terminal
Demo: Workspace UI
The main code editor of this workspace is [Code-server](https://github.com/cdr/code-server)
Demo: Code-server
Workspace has full-size browser-base terminal
## Example
```
java -version
```
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
```

# Gradle
Copy example project
```
cp -r /home/abc/example /home/project/example
cd /home/project/example
```
Check Gradle installation, run Gradle from the command-line
```
cd /home/project/example
gradle
```
Initialize Gradle
```
gradle init
```
Now that Gradle is installed, see what it can do
```
gradle tasks
```
Build project with Gradle
```
gradle build
```
