Why bootstrap.properties is ignored by spring-cloud-starter-config?

My goal is to get the config for world-service from a config-service.
The architecture:
config-service with dependency spring-cloud-config-server at localhost:8888
world-service with dependency the spring-web and spring-cloud-starter-config.
What I have done:
I have set up the Config Server and send a GET request to http://localhost:8888/hello-service/master and the config server get the hello-service.properties from the config-repo repository. (If you need the config-service's source code, I will push it to this repository.)
My expected result:
The world-service use port 8081.
My actual result:
The world-service use port 8080.
bootstrap.properties
spring.application.name=world-service
spring.cloud.config.uri=http://localhost:8888

With Spring Cloud 2020, they made a change in how bootstrap works and you have to include a new starter: spring-cloud-starter-bootstrap.

I spent a day on it and finally found a solution. It may help others
You need to add new dependency
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>
According to the Spring Cloud 2020.0
Bootstrap, provided by spring-cloud-commons, is no longer enabled by
default. If your project requires it, it can be re-enabled by
properties or by a new starter.
To re-enable by properties set spring.cloud.bootstrap.enabled=true or
spring.config.use-legacy-processing=true. These need to be set as an
environment variable, java system property or a command line argument.
The other option is to include the new spring-cloud-starter-bootstrap
(in your POM file).
I used the first option and that worked for me.

Spring Boot 2.4 introduced a new way to import configuration data via the spring.config.import property. This is now the default way to bind to Config Server.
To connect to config server set the following in application.yml:
spring:
application:
name: APPLICATION_NAME
config:
import: optional:configserver:http://USER:PASSWORD#MY_HOST:PORT/
You can see more details in: https://docs.spring.io/spring-cloud-config/docs/3.0.0/reference/html/#config-data-import

How to download maven dependency as *.jar file?

I attempt to implement the example from here, but upon the Maven dependencies installation I can't find jar file amongst downloaded dependencies.

I am able to download all the jars except geotools related jars. When I clean and run the project, in the .m2 folder I am not able to see the geotool related jars. Even in the maven repository I am not able to download the jar file.
Maven repo
Is there any alternative way to proceed?

The repository run by Boundless has been replaced by one hosted by OSGeo. The OSGeo webdav repo was merged into the new OSGeo repo. Details are here (https://docs.geotools.org/latest/userguide/tutorial/quickstart/maven.html)
Replace this block
<repository>
<id>osgeo</id>
<name>Open Source Geospatial Foundation Repository</name>
<url>http://download.osgeo.org/webdav/geotools/</url>
</repository>
<repository> <!--Add the snapshot repository here-->
<snapshots>
<enabled>true</enabled>
</snapshots>
<id>opengeo</id>
<name>OpenGeo Maven Repository</name>
<url>http://repo.opengeo.org</url>
</repository>
with
<repository>
<id>osgeo</id>
<name>OSGeo Release Repository</name>
<url>https://repo.osgeo.org/repository/release/</url>
<snapshots><enabled>false</enabled></snapshots>
<releases><enabled>true</enabled></releases>

<repository>
<id>osgeo-snapshot</id>
<name>OSGeo Snapshot Repository</name>
<url>https://repo.osgeo.org/repository/snapshot/</url>
<snapshots><enabled>true</enabled></snapshots>
<releases><enabled>false</enabled></releases>
</repository>

If you paste the Open Source Geospatial Foundation Repository URL in your web browser and hit enter it will return 404 Not Found error. This happens when Maven attempts to connect to that resource to fetch dependency for you but it's no longer available. However, if you pay close attention to Maven Repo link, there is a note:
Note: this artefact is located at Boundless repository (https://repo.boundlessgeo.com/main/)
Try to replace http://download.osgeo.org/webdav/geotools/ with a given in the note URL and run mvn clean install
Please let me know if that worked for you.

Missing artifact in maven internal repository

I have added two jar files to my internal repository and created its corresponding folder directory as shown below in image. but it is showing compile time error in my pom.xml where i have added the dependency for both the jars, saying "Missing artifact common:common-jar:jar:1.0" and "Missing artifact mediator:mediator-jar:jar:1.0"
look at my pom.xml below
<properties>
<jdk.version>1.7</jdk.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<!-- Maven plugin & MOJO versions -->
<version.maven-compiler-plugin>3.1</version.maven-compiler-plugin>
</properties>
<repositories>
<repository>
<id>in-project</id>
<name>In Project Repo</name>
<url>file://${basedir}/libs</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>common</groupId>
<artifactId>common-jar</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>mediator</groupId>
<artifactId>mediator-jar</artifactId>
<version>1.0</version>
</dependency>
</dependencies>
please suggest what to do.
I think there is some problem identifying value for ${basedir} but i have also tried ${project.basedir} as well, it is also not working.

The problem lies in your url tag. Instead of <url>file://${basedir}/libs</url> try removing the double slash before ${basedir}: <url>file:${basedir}/libs</url>
You have a nice guide here if you want to check it.

First : Never use <scope>system</scope>
Follow the Example:
Project folder - C:\UX\X5SCX\GIT_STORE\SRC\FACTOR\fwk\broker\lib
<repositories>
<repository>
<id>local-repo</id>
<url>file://${basedir}/lib</url>

Restlet and Jackson: java.lang.NoClassDefFoundError: org/codehaus/jackson/JsonFactory

I'm trying to make Restlet work with Jackson with the following Java code:
public class HelloWorldResource extends ServerResource{
#Get("json")
public Todo represent()
{
Todo t = new Todo();
t.setId("1");
t.setDescription("hello");
t.setSummary("world");
return t;
}
//...
}
When I run the program I get an error:
java.lang.NoClassDefFoundError: org/codehaus/jackson/JsonFactory
These are the jars I'm using:
Why can't it find the dependencies?
EDIT:
I solved the problem by adding this jar to the classpath.
I'm still interested to know if there are some mistakes/redundancies in the jars I'm adding.

You should configure your application using Maven. That way, we will have automatically all required dependencies (included dependencies of dependencies transitively).
In your case, we could use something like that within your file pom.xml:
<?xml version="1.0" encoding="UTF-8"?>

Cannot build Spring 4 project with Maven

How do I know which version to provide in the pom.xml for this?

Check whether http://repo.spring.io/libs-snapshot is in pom.xml. If not, Add http://repo.spring.io/libs-snapshot to maven repository.

And upgrade the maven to 3.0.5 above.

In my case, removing the ~/.m2/repository/org/springframework/boot folder and then cleaning the project resolved the issue. After this issue, I also faced another issue in which STS complained that my maven project was not updated. However, right clicking on the issues in the Markers area and selecting Quick Fix popped up a window which prompted me to update the maven projects. Selecting the projects and clicking the update button in this window resolved the issue.

I specified d goals as "spring-boot:run" (without quote) it works for me
procedure: right click on myproject>run as >run configurations >click on mavenbuild>goals(specify goal name)>run
