Food Packaging (Java, Quarkus, Maven)

Schedule food packaging orders to manufacturing lines, to minimize downtime and fulfill all orders in time.

• Run the application

• Run the packaged application

• Run the application in a container

• Run it native

Prerequisites

1. Install Java and Maven, for example with Sdkman:

   $ sdk install java
   $ sdk install maven

Run the application

1. Git clone the timefold-quickstarts repo and navigate to this directory:

   $ git clone https://github.com/TimefoldAI/timefold-quickstarts.git
   ...
   $ cd timefold-quickstarts/java/food-packaging

2. Start the application with Maven:

   $ mvn quarkus:dev

3. Visit http://localhost:8080 in your browser.

4. Click on the Solve button.

Then try live coding:

1. Make some changes in the source code.

2. Refresh your browser (F5).

Notice that those changes are immediately in effect.

Run the packaged application

When you’re done iterating in quarkus:dev mode, package the application to run as a conventional jar file.

1. Compile it with Maven:

   $ mvn package

2. Run it:

   $ java -jar ./target/quarkus-app/quarkus-run.jar

   Note	To run it on port 8081 instead, add -Dquarkus.http.port=8081.

3. Visit http://localhost:8080 in your browser.

4. Click on the Solve button.

Run the application in a container

1. Build a container image:

   $ mvn package -Dcontainer

   The container image name

2. Run a container:

   $ docker run -p 8080:8080 --rm $USER/food-packaging:1.0-SNAPSHOT

Run it native

To increase startup performance for serverless deployments, build the application as a native executable:

1. Install GraalVM and gu install the native-image tool

2. Compile it natively. This takes a few minutes:

   $ mvn package -Dnative -DskipTests

3. Run the native executable:

   $ ./target/*-runner

4. Visit http://localhost:8080 in your browser.

5. Click on the Solve button.
