[perapallamaneesha]

Hi, I am a new bee in Tars, I have two issues while trying out examples tars-spring-boot-http-server and tars-spring-boot-server on Tarsweb.

ISSUE1: While converting tars-springboot-server into jar file using "mvn package" i have encountered the following error
[centos@tars-mater1 tars-spring-boot-server]$ mvn package
[INFO] Scanning for projects...
[ERROR] [ERROR] Some problems were encountered while processing the POMs:

ISSUE2: Also after uploading tars-spring-boot-http-server.jar file in tarsweb i am getting "Failed:system error" in publishing timestamp of uploaded package.

Can someone please give thier valuable inputs on resolving this issue.Thanks in advance.
