Quarkus

Step 1: Have a Quarkus project

Obviously you need a valid Quarkus project.

Step 2: Add Mateu dependencies

In case you are using maven:

<dependency>
    <groupId>io.mateu</groupId>
    <artifactId>quarkus-core</artifactId>
    <version>2.4.94</version>
</dependency>
<dependency>
    <groupId>io.mateu</groupId>
    <artifactId>annotation-processor-quarkus</artifactId>
    <version>2.4.94</version>
</dependency>
  <!-- you need the one below if you want to also serve the static content -->
<dependency>
    <groupId>io.mateu</groupId>
    <artifactId>vaadin-lit</artifactId>
<!--
available artifacts are: redhat-lit, sapui5-lit, redwood-lit and  vaadin-lit
-->
    <version>2.4.94</version>
</dependency>

Or, in case you are using Gradle:

    implementation("io.mateu:quarkus-core:2.4.94")
    implementation("io.mateu:vaadin-lit:2.4.94")
    annotationProcessor("io.mateu:annotation-processor-quarkus:2.4.94")

Step 3: Create your Mateu UI

Nothing special is required. Just annotate your class with @UI:

package com.example.demo;

import io.mateu.uidl.annotations.UI;

@UI("")
public class HelloWorld {

}

When you run you spring boot application, you will find your ui at http:localhost:8080 (for the code above) as expected:

Troubleshooting

In case you are using a maven project and you are setting custom annotation processor paths (e.g. because you are using mapstruct) you must add the annotation processor from Mateu, in your pom.xml:

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.13.0</version>
                <configuration>
                    <source>21</source>
                    <target>21</target>
                    <annotationProcessorPaths>
                        <path> <!-- when using mapstruct -->
                            <groupId>org.mapstruct</groupId>
                            <artifactId>mapstruct-processor</artifactId>
                            <version>${org.mapstruct.version}</version>
                        </path>
                        <path>
                            <groupId>io.mateu</groupId>
                            <artifactId>annotation-processor-quarkus</artifactId>
                            <version>2.4.94</version>
                        </path>
                        <!-- other annotation processors -->
                    </annotationProcessorPaths>
                </configuration>
            </plugin>
        </plugins>
    </build>
