Spring Boot 2.0.1 fails to start when web application uses spring-boot-starter-test

[beldenge]

A Spring Boot 2.0.1 web application will not start if the spring-boot-starter-test dependency is included.

https://stackoverflow.com/questions/49917449/cannot-start-tomcat-server-when-having-spring-boot-starter-test-dependency-in/50157009#50157009

It seems to be related to the spring-core dependency within spring-boot-starter-test. If that specific dependency is excluded, then Spring Boot starts up fine.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
        </exclusion>
    </exclusions>
</dependency>

Thanks for the report, but it's not clear from the information provided what the problem might be.

A test-scoped dependency should have no effect at all on the classpath when you run your application so I don't understand why the exclusion you've shown should make any difference. To help us diagnose the problem, can you please provide a minimal sample that reproduces the problem along with details of exactly how you're attempting to start the application.

+1, I have exact same issue.

@wanghongfei a +1 without a sample is not helping. I've created a sample project with web and test (removing the test scope for the latter) and the app starts just fine as @wilkinsona indicated above.

If you want us to diagnose the problem you're experiencing, we need a sample that we can run ourselves.

hi, I created a demo project that is able to reproduce this issue:
https://github.com/wanghongfei/springboot-issue-demo

This application is unable to start unless you uncomment specific code snippet in pom.xml which excluding the spring-core dependency.

Sorry about the last useless comment

Thanks for the sample. This is a duplicate of #12457.

You need to exclude commons-logging:common-logging which is currently being pulled in as a transitive dependency of org.hyperledger.fabric-sdk-java:fabric-sdk-java. You can do so by updating your pom like this:
