# $ARTIFACT_ID

Projeto criado automaticamente com:

- Java $JAVA_VERSION
- Spring Boot $SPRING_BOOT_VERSION
- Vaadin $VAADIN_VERSION
- Maven

## Executar em modo de desenvolvimento

\`\`\`bash
mvn spring-boot:run
\`\`\`

Depois acesse:

\`\`\`text
http://localhost:8080
\`\`\`

## Executar os testes

\`\`\`bash
mvn test
\`\`\`

## Gerar pacote de desenvolvimento

\`\`\`bash
mvn clean package
\`\`\`

## Gerar pacote de produção

\`\`\`bash
mvn clean package -Pproduction
\`\`\`

O arquivo gerado estará em:

\`\`\`text
target/$ARTIFACT_ID-1.0-SNAPSHOT.jar
\`\`\`

## Executar o JAR

\`\`\`bash
java -jar target/$ARTIFACT_ID-1.0-SNAPSHOT.jar
