Spring Boot is not compatible with this Spring Cloud release train

Question

I am trying to create shaded jar for my spring project with bellow pom.xml, which runs fine in IDE but when I run mvn clean package and execute the jar with java -jar .\flink-0.0.1-SNAPSHOT-test.jar I am getting:

Your project setup is incompatible with our requirements due to following reasons:

• Spring Boot [0.0.1-SNAPSHOT] is not compatible with this Spring Cloud release train
• Change Spring Boot version to one of the following versions [2.6.x, 2.7.x] .

I checked spring cloud compability matrix where spring cloud 2021.0.x is compatible with spring boot 2.6.x.

<groupId>com.example</groupId>
<artifactId>flink</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>flink</name>
<description>flink</description>

<properties>
    <spring-cloud.version>2021.0.1</spring-cloud.version>
</properties>

Project currently contain only single Main Class:

@SpringBootApplication
public class Application
{
    public static void main(String[] args)
    {
        SpringApplication.run(Application.class, args);
    }
}

Answer 1

Shading the jar means that the version compatibility that checks the manifest is broken. Set spring.cloud.compatibility-verifier.enabled=false
