Intro
To start, open Quickstart page 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
The main code editor of this workspace is 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
(taken from https://spring.io/guides/gs/maven/)
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
