>From my build.gradle:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.10.RELEASE")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
jar {
baseName = 'calculator'
version = '0.1.0'
}
repositories {
mavenCentral()
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {
compile("org.springframework.boot:spring-boot-starter-web")
testCompile("org.springframework.boot:spring-boot-starter-test")
compile("org.springframework.kafka:spring-kafka:1.3.2.RELEASE")
testCompile("org.springframework.kafka:spring-kafka-test")
}
And this is from my project structure. I wonder if that is part of the
problem, having .10 and .11?
- Gradle: org.apache.kafka:kafka-clients:0.11.0.0
- Gradle: org.apache.kafka:kafka-clients:test:0.11.0.0
- Gradle: org.apache.kafka:kafka_2.11:0.10.1.1
- Gradle: org.apache.kafka:kafka_2.11:test:0.10.1.1
