Spring Cloud Config Failed to start config server with message: Error creating bean with name 'environmentEncryptor' ...

Spring Cloud Config Server failed to start with the message below(omitted lots of stacktraces).

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'environmentEncryptor' defined in class path resource [org/springframework/cloud/config/server/config/EncryptionAutoConfiguration$EncryptorConfiguration.class]: Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [org.springframework.cloud.config.server.encryption.CipherEnvironmentEncryptor] from ClassLoader [sun.misc.Launcher$AppClassLoader@73d16e93]

...
...
Caused by: java.lang.NoClassDefFoundError: org/springframework/cloud/config/environment/Environment

My build configs are like below(just partial).

// build.gradle
buildscript {
  ext {
    springBootVersion = '2.1.2.RELEASE'
    springCloudVersion = 'Greenwich.RELEASE'
  }
  dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
  }
}

dependencies {
  implementation "org.springframework.cloud:spring-cloud-config-server"
}

and application.yml for this application.

#application.yml
spring:
  application:
    name: config-server
  profiles:
    active: native
  cloud:
    config:
      server:
        native:
          search-locations: classpath:/configs

Is there anything I misunderstood configuration?

Can you show the depenency tree output from gradle.

Comment From: themuser

Below is the dependency tree. This project is in standalone environment depends on standalone nexus.

Seems like dependency for spring-cloud-config-client is missing comparing to working-correctly-version. Still does not work after manually adding spring-cloud-config-client dependency though.

compileClasspath - Compile classpath for source set 'main'.

On Standalone Environment

\--- org.springframework.cloud:spring-cloud-config-server -> 2.1.0.RELEASE
// end of tree

In this case, remote mvn repository is Nexus On-Premise.

On Internet Environment

\--- org.springframework.cloud:spring-cloud-config-server -> 2.1.0.RELEASE
     +--- org.springframework.cloud:spring-cloud-config-client:2.1.0.RELEASE
     |    +--- org.springframework.boot:spring-boot-autoconfigure:2.1.2.RELEASE (*)
     |    +--- org.springframework.cloud:spring-cloud-commons:2.1.0.RELEASE
     ...
     ...

In this case, remote mvn repository is mavenCentral()

Not much we can do about an internal Nexus problem

Comment From: themuser

Resolved

Just renewed internal Nexus dependency for Spring Cloud Greenwich.SR1(previously Greenwich.RELASE) which seems not to be a fundamental solution.

Thank you for the support :)

Comment From: sanseervi

Hi I am getting a similar issue with Spring cloud version Huxton.SR3 and Spring Boot version 2.2.6. Please suggest

Comment From: themuser

@sanseervi If your are doing it in on-prem, why don't you make your project built in the internet environment and compare the dependency trees?

Comment From: SubhankarMukherjee

I am also facing the same issue. My Spring boot version is 2.6.0 Snapshot and spring cloud version is 021.0.0-SNAPSHOT. Kindly suggest
