spring cloud quick-start demo maven - java

I want to learn Spring Cloud from the official demo.
https://projects.spring.io/spring-cloud/#quick-start
The maven pom looks like this:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.1.RELEASE</version>
</parent>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Finchley.RC2</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<dependencies>
<dependency>
<groupId></groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
<dependency>
<groupId></groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
</dependencies><repositories>
<repository>
<id>spring-milestones</id>
<name>Spring Milestones</name>
<url>https://repo.spring.io/libs-milestone</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
I am confused. Where is the groupId for spring-cloud-starter-config?
When i copy it into intellij, it says xml tag has empty body. How can i run the demo?


You add groupId <groupId>org.springframework.cloud</groupId>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>

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 :

The spring-security-oauth2 project currently has a hard dependency on Spring MVC and the Servlet API. Please refer to WebFlux oauth2 doc

You need to specify ${spring-cloud.version}. Add properties section into your pom:
<properties>
<spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>
</properties>
Ofc, instead of "Greenvich.RELEASE" you can use any other version of spring-cloud-dependencies

Well, you commented out
<!--<properties>-->
<!--<java.version>1.8</java.version>-->
<!--<spring-cloud.version>Finchley.M8</spring-cloud.version>-->
<!--</properties>-->
So Maven has no idea how to get the placeholder for
<version>${spring-cloud.version}</version>
Un-comment these lines and you should be good to go.
There is also a new version for that module, Greenwich.RELEASE.

Dependency requires the version number. Add the version number like below or refer https://spring.io/projects/spring-cloud-gcp for the latest version of the dependency that can be used.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-gcp-dependencies</artifactId>
<version>1.2.8.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>

Above your <dependencies> starting bracket, add the following:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Finchley.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<dependencies>
...
<dependency>
...
</dependency>
...
</dependencies>

I fixed this issue in Intellij Idea by doing followings steps:
Click on the maven tab and type the following command:
mvn clean install
After this you will get errors about SpringFramework. You can fix it by doing:
Right click on project
go to maven in the contextual menu
And click on "reload project"

On line 73,66 i have used command String.join(); What can I do to fix this? I created application with Tomcat 7 in OpenShift.

String.join added in Java8. You are using Java 7.
Follow this tutorial, and
"export JAVA_HOME=/etc/alternatives/java_sdk_1.8.0"
in your "action_hooks/start" script. See action hooks documentation
