When I run “mvn spring-boot:run” I get the following error:
[ERROR] org.springframework.boot.context.embedded.tomcat.TomcatStarter - Error starting Tomcat context: org.springframework.beans.factory.BeanCreationException
[WARN] org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext - Exception encountered during context initialization - cancelling refresh attempt
org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.boot.context.embedded.EmbeddedServletContainerException: Unable to start embedded Tomcat
I'm not sure what's causing it... my pom.xml file is too long to post here but I wonder if this is the issue and I should comment out the exclusions:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<artifactId>spring-boot-starter-tomcat</artifactId>
<groupId>org.springframework.boot</groupId>
</exclusion>
</exclusions>

I am getting a FileNotFoundException during Spring Boot initiation for org/springframework/boot/actuate/health/HealthAggregator.class. This seem related to https://github.com/spring-projects/spring-boot/issues/19860 but that was back in 2.2.
I have tried different versions of Spring Boot, 2.5.9 etc, different versions of Spring Cloud, etc.
Any thoughts on how I can resolved this?

So we can conclude that exclusions simply aren't working for endpoints-management-control-appengine-all.
I have no idea how to fix this? There has got to be some weird quirk going on.
Obviously the goal is to remove all outdated transitive servlet dependencies so that jar:file:/app/libs/tomcat-embed-core-9.0.36.jar!/javax/servlet/ServletContext.class can be auto-selected, which probably has the new virtualization method, as recommended by answers like An attempt was made to call a method that does not exist. STS.
To test these exclusions I am creating a docker container with google jib plugin and docker run
<plugin>
<groupId>com.google.cloud.tools</groupId>
<artifactId>jib-maven-plugin</artifactId>
<version>2.4.0</version>
<configuration>
<to>
<image>gcr.io/${endpoints.project.id}/endpoints-container</image>
</to>
</configuration>
</plugin>
PORT=8080 && docker run --rm -p 9090:${PORT} -e PORT=${PORT} gcr.io/project-id/endpoints-container
I'm not sure whether this detail is relevant, but something I did notice was that endpoints-management-control-appengine-all has a different package structure, with respect to the way javax servlet 2.5 is included compared to endpoints-framework.
included alongside com which doesnt happen in endpoints-framework
Is there a way to tell which dependency/annotation is missing in case of this exception?
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Invocation of init method failed; nested exception is java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy
I'm using spring-boot 1.5.17.RELEASE and spring-cloud Edgware.SR5, as per start.spring.io. I have spring-boot-starter-web, spring-cloud-starter-config and spring-cloud-starter-eureka included. It's a simple jar that's supposed to be deployed on WildFly alongside Keycloak 4.5.0.Final to register it in Netflix's Eureka instance.
I've observed that solution to that problem is always different. Mine was to exclude spring-webmvc from spring-boot-starter-web dependency that I've already had:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
</exclusion>
</exclusions>
</dependency>
I'm trying to do a ConfigServer with a remote repository.
The ConfigServer pom's file is:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bus-amqp</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-monitor</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
Inthe the properties file, i have the url, user and password of the repository. Is necessary anything else?. The file is like:
server.port:8888
spring.cloud.config.server.git.uri:git#gitlab.com:user/repo.git
spring.cloud.config.server.git.uri.username:user
spring.cloud.config.server.git.uri.password:password
spring.profiles.active:config-monitor
rabbitmq.host:rabbitmq
rabbitmq.port:5672
rabbitmq.username:guest
rabbitmq.password:guest
spring.cloud.bus.enabled:true
spring.cloud.config.server.monitor.gitlab.enabled:true
And I created a Webhook in gitLab with url http://localhost:8888/monitor too.
But when a client try to start, the ConfigServer's console shows:
**2017-03-14 23:46:35.767 ERROR 10595 --- [nio-8888-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: Cannot clone or checkout repository] with root cause

Dou you know how can i resolver it?
Thanks!
I can run my app and there's no problem at all but when i'm adding
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-solr</artifactId>
<version>1.1.0.RELEASE</version>
</dependency>
to my pom file it throws:
15:59:18,172 ERROR [org.springframework.web.context.ContextLoader] (MSC service thread 1-3) Context initialization failed: java.lang.IllegalStateException: Cannot load configuration class: eu.combc.webuzu.configuration.SecurityConfig
any idea what's going on?
check with this :
<dependency>
<groupId>org.apache.solr</groupId>
<artifactId>solr-solrj</artifactId>
<version>4.10.1</version>
</dependency>
