How to tell quarkus to use java 17?

I keep gettring build error saing that I'm using a preview feature (switch expressions):

Service.java:28: error: patterns in switch statements are a preview feature and are disabled by default.
      case CalssA sr -> sr.getMeterReadings();
           ^
  (use --enable-preview to enable patterns in switch statements)

I clearly said in build.gradle that I want to use Java 17. Switch expression were released in Java 14.

Here are my gradle.properties, settings.gradle, and build.gradle:

quarkusPluginVersion=3.0.1.Final
quarkusPlatformArtifactId=quarkus-bom
quarkusPluginId=io.quarkus
quarkusPlatformGroupId=io.quarkus.platform
quarkusPlatformVersion=3.0.1.Final

pluginManagement {
    repositories {
        mavenCentral()
        gradlePluginPortal()
        mavenLocal()
    }
    plugins {
        id "${quarkusPluginId}" version "${quarkusPluginVersion}"
    }
}
rootProject.name='upc'

buildscript {
    repositories {
        mavenCentral()
        gradlePluginPortal()
        mavenLocal()
    }
    dependencies {
        classpath 'com.h2database:h2:1.4.197'
    }
}


plugins {
    id 'java'
    id 'io.quarkus'
    id 'org.flywaydb.flyway' version '9.8.1'
}

repositories {
    mavenCentral()
    mavenLocal()
}

dependencies {
    def lombok_version = '1.18.26'
    def map_struct_version = '1.5.5.Final'

    implementation enforcedPlatform("${quarkusPlatformGroupId}:${quarkusPlatformArtifactId}:${quarkusPlatformVersion}")

    testAnnotationProcessor "org.projectlombok:lombok:${lombok_version}"
    testAnnotationProcessor "org.mapstruct:mapstruct-processor:${map_struct_version}"

    testImplementation 'io.quarkus:quarkus-junit5'
    testImplementation 'io.rest-assured:rest-assured'
}

group 'org.acanthite'
version '0.1'

java {
    sourceCompatibility = JavaVersion.VERSION_17
    targetCompatibility = JavaVersion.VERSION_17
}

test {
    systemProperty 'java.util.logging.manager', 'org.jboss.logmanager.LogManager'
}



compileJava {
    options.encoding = 'UTF-8'
    options.compilerArgs += [
            '-parameters',
            '-Amapstruct.defaultComponentModel=cdi',
            '-Amapstruct.defaultInjectionStrategy=constructor'
    ]
}

compileTestJava {
    options.encoding = 'UTF-8'
    options.compilerArgs += [
            '-parameters',
            '-Amapstruct.defaultComponentModel=cdi',
            '-Amapstruct.defaultInjectionStrategy=constructor'
    ]
}

Here are IDEA settings for project: enter image description here enter image description here

What am I doing wrong? Is there any other place I need to specify Java version?

I've figured out what's wrong.

Gradle and quarkus are fine and work perfectly.

The problem is that I'm not using switch expressions but switch pattern matching, which looks similar, but is a totally different thing. It is a preview feature in Java 17. Nevertheless, there is a compiler flag --enable-preview which somehow works for non-test builds, but fails when running tests. See this issue: https://github.com/quarkusio/quarkus/issues/10472
