Add the database details in customDictionary.xml in the resources folder. Make changes to the Default.piper if needed

STEP 3: Build the java application, test it and package it

cd quick-ctakes
./mvnw clean compile quarkus:dev
mvn clean package -DskipTests

More about Quarkus

This project uses Quarkus, the Supersonic Subatomic Java Framework.

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./mvnw quarkus:dev

Packaging and running the application

The application is packageable using ./mvnw package. It produces the executable quick-ctakes-1.0.0-SNAPSHOT-runner.jar file in /target directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/lib directory.

The application is now runnable using java -jar target/quick-ctakes-1.0.0-SNAPSHOT-runner.jar.

Creating a native executable

You can create a native executable using: ./mvnw package -Pnative.

Or you can use Docker to build the native executable using: ./mvnw package -Pnative -Dquarkus.native.container-build=true.

You can then execute your binary: ./target/quick-ctakes-1.0.0-SNAPSHOT-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/building-native-image-guide .
