Develop Reference

While running spring-cloud microservices project, the server is not starting up?

In my project, we are using latest version of
Spring-cloud-loadbalancer, spring-cloud gateway and Resilience4j.
JDK version 1.8
IDE - Eclipse Oxygen .2
While running the SpringBootApplication, I'm getting below error -
> Exception in thread "main" java.lang.IllegalStateException: Failed to read Class-Path attribute from manifest of jar file:/C:/Users/VaibhavAtray/.m2/repository/org/springframework/boot/spring-boot-actuator/2.1.4.RELEASE/spring-boot-actuator-2.1.4.RELEASE.jar

at org.springframework.boot.devtools.restart.DefaultRestartInitializer.getUrls(DefaultRestartInitializer.java:92)

Everything looks good, but still the application is not running...

You need at least 2.4.X Spring boot since Spring Cloud 2020.0.X requires at least this much version to work.
Hope this will work.

Maven build fails: package does not exist

I'm having a strange problem where I have one maven project that has a dependency on another maven project (both are mine) and I'm getting a compilation error complaining that packages don't exist - even though they do.

I've done research (including in this forum) and found numerous items on this issue. I've taken some of the advice found, but it still doesn't work. I don't understand what I'm doing wrong.
Here's the scenario:
Project A provides functionality that Project B needs to use.

When I build my maven projects I almost always use mvn clean install. I've gone as far as completely removing my ~/.m2/repository and rebuilding, but it still fails.

As the documentation explains, a spring boot project isn't suitable as a dependency for the projects, as the class files are placed somewhere where they can't be seen by the other project, in BOOT-INF/classes: https://docs.spring.io/spring-boot/docs/1.5.x/maven-plugin/examples/repackage-classifier.html

Jar file run failed of a Spring boot application

I have these Spring boot applications using a microservice architecture, and I needed to dockerize them, so I generated a Jar file for each, all of them are working just fine when I run them from IntelliJ, but the jar file is always showing an error when I try to run it, I added
false
as I saw in a post earlier talking about the same error, but still the same error, knowing I tried generating the jar file using
mvn clean package AND
mvn clean install
here is my pom.xml of inventory package :

Removing unneeded jars in External library to to deploy on Tomcat server

I'm trying to deploy on Tomcat server and i'm getting the error below even after removing duplicated dependencies ( from maven I click on Clean then Install ).
Error :
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.springframework.boot.autoconfigure.security.oauth2.client.OAuth2ClientPropertiesRegistrationAdapter.getBuilderFromIssuerIfPossible(OAuth2ClientPropertiesRegistrationAdapter.java:83)
The following method did not exist:
org.springframework.security.oauth2.client.registration.ClientRegistrations.fromIssuerLocation(Ljava/lang/String;)Lorg/springframework/security/oauth2/client/registration/ClientRegistration$Builder;
The method's class, org.springframework.security.oauth2.client.registration.ClientRegistrations, is available from the following locations:

It was loaded from the following location:
file:/C:/Users/user/Desktop/apache-tomcat-8.5.50/webapps/E-Services-Portal-0.0.1-SNAPSHOT/WEB-INF/lib/spring-security-oauth2-client-5.1.0.RELEASE.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of org.springframework.security.oauth2.client.registration.ClientRegistrations
This error is coming after I build my war file by clicking in Install and copy the file and paste it in webapp folder in Tomcat server then when I start tomcat for deploying , I will get the same error.
This is my POM file , i believe the error is coming from here :
