Answer 1

After couple of days struggle, We found that answer,

if SCM is not configured then "Technical Debt Ratio on new code" won't be computed (details in development story https://jira.sonarsource.com/browse/SONAR-5876)

For Maven based project,

• Add SCM tag details in POM file (https://maven.apache.org/scm/maven-scm-plugin/usage.html)

• Enable and Add SCM details in SonarQube

  A ) Go to Administration --> General Settings --> SCM (Left side menu)
       1.set as false to "Disabled the SCM Sensor" and SCM provider "svn"
       2.Add User name and password in SVN
  

• Run the Sonar scan your project
