Hi Anand,
> ... *not supported in -source 7 ...*
It seems that you were passing "-source 7" to java in your maven setting
while Ratis requires java 8. You may have a maven profile specifying it.
Please check
- The Maven install: ${maven.home}/conf/settings.xml
- A user's install: ${user.home}/.m2/settings.xml
See https://maven.apache.org/settings.html

<javac.version>8</javac.version>
<java.min.version>${javac.version}</java.min.version>

Please use "./mvnw" instead of "mvn". It may be able to solve the
compilation problem.
