Unable to start operator

[stefanbethke]

With these dependencies:

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter:3.2.3'
//    developmentOnly 'org.springframework.boot:spring-boot-devtools:3.2.0'
    implementation 'org.springframework.boot:spring-boot-starter-actuator:3.2.3'
    implementation 'org.springframework.boot:spring-boot-starter-web:3.2.3'
    implementation 'io.javaoperatorsdk:operator-framework-spring-boot-starter:5.4.1'
    implementation 'org.bouncycastle:bcpkix-jdk15on:1.70'
    // required for the fabric8 k8s client to grok k3d certificates
    annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor:3.2.3'
    compileOnly 'org.projectlombok:lombok'
    testCompileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
    annotationProcessor 'io.fabric8:crd-generator-apt:6.10.0'
    testImplementation 'org.springframework.boot:spring-boot-starter-test:3.2.3'
    testImplementation 'io.javaoperatorsdk:operator-framework-spring-boot-starter-test:5.4.1'
}

I'm getting this error on startup:

I'm not sure what to do here.

Hi @stefanbethke this seems to be a dependency mismatch, can you compare the version of fabric8 client and OkHttp within this repo and yours?

[bullshit]

@stefanbethke it would be a good idea to use spring dependency-management and spring boot plugin and let them manage the version numbers.

I can give you an example in for gradle with kotlin.

build.gradle.kts

plugins {
  id("org.springframework.boot") version "3.2.3"
  id("io.spring.dependency-management") version "1.1.4"
  kotlin("jvm") version "1.9.22"
  kotlin("plugin.spring") version "1.9.22"
}

dependencies {
  implementation("org.springframework.boot:spring-boot-starter-actuator")
  implementation("org.springframework.boot:spring-boot-starter-web")
  // kotlin dependencies
  implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
  implementation("org.jetbrains.kotlin:kotlin-reflect")


  /* OperatorSDK Spring Boot starter */
  implementation("io.javaoperatorsdk:operator-framework-spring-boot-starter:5.4.1")
  // Generating CustomResourceDefinitions from Java classes
  annotationProcessor("io.fabric8:crd-generator-apt")

  annotationProcessor("org.springframework.boot:spring-boot-configuration-processor")
  testImplementation("org.springframework.boot:spring-boot-starter-test")

  // Test OperatorSDK
  testImplementation("io.javaoperatorsdk:operator-framework-spring-boot-starter-test:5.4.1") {
    /* Exclude sample code that gets unnecessary packaged
    fixed with PR https://github.com/operator-framework/josdk-spring-boot-starter/pull/127
    next version will include the fix
    */
    exclude(
        group = "io.javaoperatorsdk",
        module = "operator-framework-spring-boot-starter-samples-common")
  }
}

configurations {
  all {
    /*
    	Exclude log4j-slf4j2-impl from io.javaoperatorsdk
    	conflicts with spring-boot-starter-logging
    */
    exclude(group = "org.apache.logging.log4j", module = "log4j-slf4j2-impl")
  }
}
