Steps to install and reproduce Finchley.RELEASE Exception due to unresolvable circular reference with use-case of postgres datasource

Requirements

• Java 8
• maven
• git
• postgres (or any other relational database engine)

---

Steps to install and reproduce

1. Clone the following repositories (spring-cloud-microservices · GitHub) onto your local machine

• microservice-config
• microservice-discovery
• microservice-client
• microservice-domain
• microservice-vault

2. Add the following lines to your /etc/hosts file

127.0.0.1 microservice-config.service-uri
127.0.0.1 microservice-discovery.service-uri
127.0.0.1 microservice-client.service-uri

3. Set the following environment variables on your local machine

GITHUB_REPO_USERNAME = <your-own-git-repository-username>
GITHUB_REPO_PASSWORD = <your-own-git-repository-password>

4. Check inside microservice-config/src/main/resources/bootstrap-dev.properties file, and update the following;

spring.cloud.config.server.git.uri = <the-absolute-the-path-to-your-own 'microservice-vault'>

5. From your terminal, change directory into microservice-domain and the issue the following commands to install the microservice-domain library into your maven repository;

cd microservice-domain
mvn clean install

6. Start your database server - in my case it was postgres but you can use any relational database (e.g mysql, oracle, etc.). Make sure you set the database connection properties in microservice-vault/microservice-client/application-dev.properties

spring.datasource.url=jdbc:postgresql://127.0.0.1:5432/microservice // <--- your own db connection url
spring.datasource.driver-class-name=org.postgresql.Driver // <--- your own db driver
spring.datasource.username=postgres // <--- your own db username
spring.datasource.password=admin // <--- your own db password
spring.datasource.platform=postgresql // <--- your own db platform

7. make sure no other application is running on ports 8890, 8891 & 8888

8. If you imported or cloned the project into your preferred IDE as a maven project, then just use your IDE to run the services in the following order - Otherwise skip to step-9;

• microservice-config
• microservice-discovery
• microservice-client

9. If you prefer to use your terminal to execute the services, do the following;

NOTE - Make sure that each service is executed only after the previous one has completely started-up and popped up a browser window

• Change directory into microservice-config and execute;

cd microservice-config
mvn exec:java

• Change directory into microservice-discovery and execute;

cd microservice-discovery
mvn exec:java

• Change directory into microservice-client and execute;

cd microservice-client
mvn exec:java

10. If all the previous steps went well, each executed service pops up a browser window when executed;

• microservice-config - launches browser window to; http://microservice-config.service-uri:8888/microservice-config/dev
• microservice-discovery - launches browser window to: http://microservice-discovery.service-uri:8090/
• microservice-client - launches browser window to: http://microservice-config.service-uri:8888/microservice-client/dev

---

To reproduce the bug, do the following;

1. Stop only the microservice-client service
2. Go into microservice-client/pom.xml and replace <spring-cloud.version>Finchley.SR1</spring-cloud.version> with <spring-cloud.version>Finchley.RELEASE</spring-cloud.version>
3. Comment the following lines at the bottom of the pom.xml file

<!--<repositories>
       <repository>
           <id>spring-milestones</id>
           <name>Spring Milestones</name>
           <url>https://repo.spring.io/milestone</url>
           <snapshots>
               <enabled>false</enabled>
           </snapshots>
       </repository>
   </repositories>-->

4. Now Re-run microservice-client from your IDE, OR Change directory into microservice-client and execute;

cd microservice-client
mvn exec:java

The exception thrown:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
