                      EmbeddedKafka failing since Spring Boot 2.6.X : AccessDeniedException: ..\AppData\Local\Temp\spring.kafka*

                      Asked 2022-Mar-25 at 12:39

                      e: this has been fixed through Spring Boot 2.6.5 (see https://github.com/spring-projects/spring-boot/issues/30243)

                      Since upgrading to Spring Boot 2.6.X (in my case: 2.6.1), I have multiple projects that now have failing unit-tests on Windows that cannot start EmbeddedKafka, that do run with Linux

                      There is multiple errors, but this is the first one thrown

                      I do not have this error when pinning kafka.version to 2.8.1 in pom.xml's properties.

                      It seems like the cause is in Kafka itself, but I have a hard time figuring out if it is spring-kafka intitializing Kafka via EmbeddedKafka incorrectly or if Kafka itself is the culrit here.

                      Anyone has an idea? Am I missing a test-parameter to set?

                      Known bug on the Apache Kafka side. Nothing to do from Spring perspective. See more info here: https://github.com/spring-projects/spring-kafka/discussions/2027. And here: https://issues.apache.org/jira/browse/KAFKA-13391

                      You need to wait until Apache Kafka 3.0.1 or don't use embedded Kafka and just rely on the Testcontainers, for example, or fully external Apache Kafka broker.

                      Install ssl-socket-demo

                      You can download it from GitHub.
                      You can use ssl-socket-demo like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the ssl-socket-demo component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
