When i try to run my spring boot application i get this Exception:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'configurationPropertiesBeans' defined in class path resource [org/springframework/cloud/autoconfigure/ConfigurationPropertiesRebinderAutoConfiguration.class]: Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [org.springframework.cloud.context.properties.ConfigurationPropertiesBeans] from ClassLoader [jdk.internal.loader.ClassLoaders$AppClassLoader@3764951d]
I think it's an version incompatibility. I imported open feign in my pom.xml and after that it wasn't working, but i dont know how to fix that. I use open feign 2.2.5.RELEASE. Here my pom.xml:

To elaborate on @M-deinum's comment, setting Spring Boot version to 2.3.4.RELEASE (instead of 2.4.2 in my case) solved the issue. In gradle this meant changing:
plugins { id 'org.springframework.boot' version '2.4.2' ... } To
plugins { id 'org.springframework.boot' version '2.3.4.RELEASE' ... } I had a same issue, and it is happening because of Spring Cloud services and Spring Boot version issues. I got rid of it by using to generate my project.
When you select all dependencies needed for your project, you can then click the Explore button and check the pom.xml file.
This issue happened to me when I tried to add dependency for Eureka-client to my pom.xml after generating project, so using IntelliJ.
I got the same error.
Then I went to Spring.io again select dependencies that I use for my project and also dependency for Eureka-client, clicked on Explore button and saw that I need to add this line of code under java version in pom.xml
<spring-cloud.version>2020.0.3</spring-cloud.version> But also this lines as well:
<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> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <excludes> <exclude> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </exclude> </excludes> </configuration> </plugin> </plugins> </build> So I just copy pasted it to my existing pom.xml and it worked!
You need to change spring boot version to Released version
from
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.4.0</version> <relativePath/> <!-- lookup parent from repository --> </parent> to
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.3.3.RELEASE</version> <relativePath /> <!-- lookup parent from repository --> </parent> Spring-Cloud - Hoxton.SR8 is not compatiable with Spring-boot 2.4.0
Just use either of the combinations:
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.4.0</version> <relativePath/> <!-- lookup parent from repository --> </parent> <spring-cloud.version>2020.0.3</spring-cloud.version> Or
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.3.0</version> <relativePath/> <!-- lookup parent from repository --> </parent> <spring-cloud.version>Hoxton.SR8</spring-cloud.version> You need to follow the release train of Spring Cloud and match the version of the Spring-boot starter. The release train is available on the spring-cloud website
The release train as of now is: Release train for spring-cloud
1just Changing to :
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> <version>3.1.1</version> </dependency> and Adding version to
<build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>2.6.6</version> </plugin> </plugins> </build> Worked Fine For Me
This worked for me. Go ti spring initialize start.spring.io and add the dependancies again. Compare your .pom with downloaded pom. I got my issue.
<spring-cloud.version>2021.0.3-SNAPSHOT</spring-cloud.version>
I was having diffent version of spring cloud hence there was a conflict.
<repository> <id>netflix-candidates</id> <name>Netflix Candidates</name> <url> <snapshots> <enabled>false</enabled> </snapshots> </repository> add this to the repository
In my case, Im using build.gradle.
Changed from:
ext { set('springCloudVersion', "Hoxton.SR1") } to:
ext { set('springCloudVersion', "2021.0.4") } Note: Im using
id 'org.springframework.boot' version '2.6.1'
