Appreciate your help.

Eureka requires Java8 to compile.

Plz reply me anyone.... please help me to solve the above error....

[Tomasz Bak]

I am not able to replicate this issue on Mac OS X or Linux. I can see you run this build on Windows, so this is most likely OS specific corner case that we do not cover. You can bypass the tests completely by running:

./gradlew -x test build

Thanks a lot tomasz. It worked. Eureka has build successfully.
After that, we need to copy the war artifacts to tomcat webapps. How to do that?
Actually i am trying to run a git hub project(https://github.com/paulc4/microservices-demo). For that, they have given the following steps.
1. In each window, change to the directory where you cloned the demo.
2. In the first window, build the application using mvn clean package
3. In the same window run: java -jar target/microservice-demo-0.0.1-SNAPSHOT.jar registration
4. Switch to the second window and run: java -jar target/microservice-demo-0.0.1-SNAPSHOT.jar accounts
5. In the third window run: java -jar target/microservice-demo-0.0.1-SNAPSHOT.jar web
6. In your favorite browser open the same two links: http://localhost:1111 and http://localhost:3333
7.You should see servers being registered in the log output of the first (registration) window. As you interact you should logging in the second and third windows.

8. In a new window, run up a second account-server using HTTP port 2223:
java -jar target/microservice-demo-0.0.1-SNAPSHOT.jar accounts 2223
9. Allow it to register itself
10. Kill the first account-server and see the web-server switch to using the new account-server - no loss of service.

I have followed till step 6, when i open eureka dashboard i am able to see two appliations has registetred. But how to kill a first account server and run second account server to check no loss of service.

Do we need to change the ports in the code?I have no idea how eureka is geeting the instances and how it is running . Please help me understand this and some help how to run this project.

I am really sorry if i am asking stupid questions . I am just a graduate and i need to run this project as proof of concept on micro services. Please help me.

[Tomasz Bak]

Each application probably runs Eureka client that is doing registration/heartbeating automatically. As soon as you kill/terminate the process, no more heartbeats are sent from the application to Eureka server, and after configured amount of time (default = 3 * heartbeat interval, which itself is 30sec), the registration record is removed.
