Welcome to the Helidon Examples! If this is your first experience with Helidon we recommend you start with our quickstart That will quickly get you going with your first Helidon application.
After that you can come back here and dig into the examples. To access these examples we recommend checking out from a released tag. For example:
git clone git@github.com:oracle/helidon.git
cd helidon
git checkout tags/2.0.0
Our examples are Maven projects and can be built and run with Java 21 or newer -- so make sure you have those:
java -version
mvn -version
Each example has a README that you will follow. To build most examples
just cd to the directory and run mvn package:
cd examples/microprofile/hello-world-explicit
mvn package
Usually the example will produce an application jar file that you can run:
java -jar target/example-name.jar
But always see the example's README for details.
