Since yesterday we have a problem on our spring boot project after clean install without change nothing of configuration of the maven files, libs or something else.
We did try to update version of pom's of SpringFrameWork and Spring boot to 1.5.4.Release.
The error that is show is:

According to ConfigurationPropertySources source, this class is around from version 2.0.0
Provides access to {#link ConfigurationPropertySource ConfigurationPropertySources}.

You probably did not upgrade your spring boot version but actually downgrade.

We used KafkaEmbedded with spring-kafka-test 2.1.4.RELEASE earlier.
While upgrading spring-kafka-test to 2.4.13.RELEASE, we required to move from KafkaEmbedded to EmbeddedKafkaBroker. This is giving below error. We are using EmbeddedKafka annotation and spring boot starter parent version is 2.0.0.RELEASE, spring-kafka version is 2.1.4.RELEASE.
Tried different versions of spring-kafka-test.

Your versions are mis-matched. Boot 2.0.x and Spring for Apache Kafka 2.4.x are no longer supported, but 2.4.x requires Boot 2.2.x or later. See the matrix on the project page:
https://spring.io/projects/spring-kafka#overview
Also see
https://spring.io/projects/spring-kafka#support
and
https://spring.io/projects/spring-boot#support
The current (OSS) supported Boot versions are 2.7.x and 3.0.x, and Spring for Apache Kafka 2.9.x and 3.0.x.
You also must use the same version for spring-kafka and spring-kafka-test; they cannot be different.
I was able to use Prometheus with the Spring Boot Version 2 before without any problem. After updating Spring Boot version to 2.1.1. Release I come across with the following error.
I upgraded Prometheus version from 0.2.0 to 0.6.0 but I still come across with the same error .
Do you think prometheus is not compatible with Spring Boot Version 2 ?
Regards

Instead of using the io.prometheus dependencies in your project try to use micrometer dependency which will handle the prometheus endpoint creation in your spring boot application as the support for prometheus is inbuilt in Spring Boot from version 2.X
As it seems simpleclient_springis still referring to Spring Boot 1.5.
You should be using the Prometheus support from Micrometer - the backing library for actuator metrics - directly in your Spring Boot 2 application. See here.
You must include micrometer-registry-prometheus to enable the prometheus backend.
All,
I've built Spring Cloud Config servers and clients before with previous versions of Spring Cloud / Spring Boot, but I seem to be having an issue with the Angel.SR4 / Boot 1.3.1 combination.
Following the basic instructions here (http://projects.spring.io/spring-cloud/docs/1.0.3/spring-cloud.html#_client_side_usage), except using the current releases of Boot and Cloud (1.3.1.RELEASE / Angel.SR4 at present), I get the following stack trace:

If I back off the Boot version to 1.2.8 the problem disappears. If I move Cloud up to Brixton.M4 the problem disappears. Is there a prescribed version combination of Boot / Cloud that should be used together? Thanks in advance.
K
Is there a prescribed version combination of Boot / Cloud that should be used together?
Yes. Angel is Boot 1.2, and Brixton is Boot 1.3. See the blog for more detail: https://spring.io/blog/2015/11/25/migrating-spring-cloud-apps-from-spring-boot-1-2-to-1-3
In my Spring Starter created Soring Boot application I switched from Spring Boot 1.3.0M1 to 1.3.0M2. When trying to start the application (either from STS 3.7.0 or via spring-boot:run at the command line) I get the following exception:

The mentioned class has been added in spring-context version 4.2.0 but when looking at the dependency tree I can see that Spring Boot 1.3.0M2 still depends on spring-context 4.1.6:

Spring Boot manages a bunch of dependencies for you and allows you to add them without specifying the version. Spring Boot is obviously based on Spring Framework and uses the latest and greatest so you should avoid at all cost to fix the spring framework version to use yourself.
If you have upgraded to a newer version (to include a bug fix or something) make sure to remove the override before you upgrade Spring Boot as the new version it requires may be incompatible with your override.
If you are using other projects that also provide a dependency management on Spring Framework (such as Spring Cloud) make sure that the dependency management of Spring Boot takes precedence. With Maven, make sure to add the spring-boot-dependencies BOM as the first entry in the <dependenciesManagement> section.
I had the same problem because my POM had a properties section with a <spring.version> tag copied from another project.
Remove any <abc.version> tag in your properties section that may conflict with Spring Boot libraries.

From the above error, application is unable to find the class defined from the jar dependencies. GenericApplicationListener is added from spring version 4.2.
Upgrade your Spring version to 4.2 and recheck.
Spring boot is using an older version of CrashHub (crashub.version in POM) that uses an old version of bouncycastle that using the class PemReader. This conflicts with the latest version of bouncycastle I am using in my application. Can you update Spring Boot or is there a work around I can do. Right now I get the exception below when I try to ssh into my application:

1.3.0 is the latest version of Crashub and that's the version that Spring Boot supports so there's nothing that can be done on the Spring Boot side of things. Assuming that you don't want to downgrade your Bouncycastle dependency, your only easy choice is to stop using Crashub.
A more involved alternative would be to fork Crashub and make the changes necessary for it to work with your desired version of Bouncycastle.
