Error starting Springboot when update version to 2.7.0 "An attempt was made to call a method that does not exist"

I updated Springboot version to 2.7.0, and after return me errors:

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.webjars.WebJarAssetLocator.scanForWebJars(WebJarAssetLocator.java:183)

The following method did not exist:

    'io.github.classgraph.ClassGraph io.github.classgraph.ClassGraph.acceptPaths(java.lang.String[])'

The calling method's class, org.webjars.WebJarAssetLocator, was loaded from the following location:

    jar:file:/home/gabriel/.m2/repository/org/webjars/webjars-locator-core/0.50/webjars-locator-core-0.50.jar!/org/webjars/WebJarAssetLocator.class

The called method's class, io.github.classgraph.ClassGraph, is available from the following locations:

    jar:file:/home/gabriel/.m2/repository/io/github/classgraph/classgraph/4.8.69/classgraph-4.8.69.jar!/io/github/classgraph/ClassGraph.class

The called method's class hierarchy was loaded from the following locations:

    io.github.classgraph.ClassGraph: file:/home/gabriel/.m2/repository/io/github/classgraph/classgraph/4.8.69/classgraph-4.8.69.jar


Action:

Correct the classpath of your application so that it contains compatible versions of the classes org.webjars.WebJarAssetLocator and io.github.classgraph.ClassGraph

Just adding my ¢2 with some code sample. I upgraded an existing project to Spring boot 2.7.5 and received a similar "warning" as

"level":"WARN","thread":"main","logger":"org.springframework.boot.web.reactive.context.AnnotationConfigReactiveWebServerApplicationContext","message":"Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: 
....
nested exception is java.lang.NoSuchMethodError: 'io.github.classgraph.ClassGraph io.github.classgraph.ClassGraph.acceptPaths(java.lang.String[])'","context":"default"}

and prevented the app from starting.

I updated org.springdoc version to the latest as in this page and it fixed the error. https://springdoc.org/#spring-webflux-support

<dependency>
  <groupId>org.springdoc</groupId>
  <artifactId>springdoc-openapi-webflux-ui</artifactId>
  <version>1.6.12</version>
</dependency>

As stated in the other answers, it is indeed springdoc-openapi-ui making trouble here. I had various errors regarding WebJarAssetLocator and/or ClassGraph, which both resolved by also updating springdoc.

Now, with spring-boot 2.7.2 and spring-doc 1.6.9, everything runs smoothly again.

Adding the following implementation to the build.gradle file also fixes the issue: implementation('org.springdoc:springdoc-openapi-ui:1.6.9')

There's an incompatibility in the transitive dependencies of org.springdoc:springdoc-openapi-ui. It depends on both org.webjars:webjars-core-locator and io.github.classgraph:classgraph but their versions are incompatible.

Spring Boot's dependency management for webjars-core-locator uses version 0.50. webjars-core-locator 0.50 would use classgraph 4.8.139 by default but, due to the way that Maven resolves version conflicts, it's being downgraded to 4.8.69.

You can fix the problem by restoring the use of 4.8.139 by adding some dependency management to your pom.xml alongside your existing import of spring-cloud-dependencies:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>${spring-cloud.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>io.github.classgraph</groupId>
            <artifactId>classgraph</artifactId>
            <version>4.8.139</version>
        </dependency>
    </dependencies>
</dependencyManagement>
