Cannot resolve method 'parse' in 'DockerImageName' when using Testcontainers and gradle in JUnit5

The test fails to compile with error Cannot resolve method 'parse' in 'DockerImageName'

@SpringBootTest @Testcontainers public class KafkaContainerTest { @ClassRule public static KafkaContainer kafka = new KafkaContainer(DockerImageName.parse("confluentinc/cp-kafka:5.2.1")); @Test public void testUsage() throws Exception { kafka.start(); testKafkaFunctionality(kafka.getBootstrapServers()); } //... } 

build.gradle

plugins { id 'org.springframework.boot' version '2.3.4.RELEASE' id 'io.spring.dependency-management' version '1.0.10.RELEASE' id 'java' } group = 'com.example' version = '0.0.1-SNAPSHOT' sourceCompatibility = '1.8' repositories { mavenCentral() } dependencies { implementation 'org.springframework.boot:spring-boot-starter' implementation 'org.springframework.boot:spring-boot-starter-web' implementation 'org.springframework.boot:spring-boot-starter-webflux' compile group: 'org.springframework.boot', name: 'spring-boot-starter-validation', version: '2.3.4.RELEASE' implementation 'org.apache.kafka:kafka-streams' implementation 'org.springframework.kafka:spring-kafka' compileOnly 'org.projectlombok:lombok' developmentOnly 'org.springframework.boot:spring-boot-devtools' annotationProcessor 'org.projectlombok:lombok' testCompile 'org.projectlombok:lombok' testCompile group: 'io.projectreactor', name: 'reactor-test', version: '3.3.10.RELEASE' testImplementation 'io.projectreactor:reactor-test' testImplementation 'org.springframework.kafka:spring-kafka-test' testImplementation 'com.google.guava:guava:23.0' testImplementation 'org.testcontainers:testcontainers:1.14.3' testImplementation "org.testcontainers:junit-jupiter:1.14.3" testImplementation 'org.testcontainers:kafka:1.14.3' testImplementation('org.springframework.boot:spring-boot-starter-test') { exclude group: 'org.junit.vintage', module: 'junit-vintage-engine' } } test { useJUnitPlatform() } 

When navigating to DockerImageName class in IntelliJ it says Library source does not match the bytecode for class DockerImageName. This answer did not help.

Update

This works

testImplementation 'org.testcontainers:testcontainers:1.15.0-rc2' testImplementation "org.testcontainers:junit-jupiter:1.15.0-rc2" testImplementation 'org.testcontainers:kafka:1.15.0-rc2'

The static parse method was only added to the testcontainers library back in July. You're using version 1.14.3, which was released in May. I expect that if you upgrade the version of the library to a 15.X (version 1.15.0-rc2 seems to be the latest), I expect your problem will be resolved.

Alternately, you can change your usage of that library to what it was capable of in version 1.14.3.

UPDATE: I just saw (and finally understood) @tgdavies's suggestion that you can just call the DockerImageName object's constructor directly via:

return new DockerImageName(fullImageName);
