Please help, Error occured while installing OpenMRS SDK


I am new to this community and hope to contribute to OpenMRS with GSoC 2018. I already went through the following documentation,

Then I tried to install the OpenMRS SDK using this documentation. , But I got some errors while downloading the packages.

mvn errror java.lang.RuntimeException: Unexpected error: the trustAnchors parameter must be non-empty

How can I overcome from this issue to continue my installation? Please help me to install the Refrence application using OpenMRS SDK.

Have you checked the required Java version for the installation? Please update your Java and maven to required version before trying to install SDK.

Thanks @suthagar23

The problem is occurred due to the update for Ubuntu 17.10. Now I have fixed it.
