I have a maven project forked and cloned from a git repo onto my eclipse. It is build on Java 8. The first thing i do is perform a
mvn clean install
But I get following failure message:

and the compilation set up:
No matter how many times I build the project, i get the same error. Even after cleaning the project and refreshing it from eclipse doesn’t help. Please guide.
UPDATE:
After adding the properties to set maven compiler plugin
<properties> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties>
,
am getting the below error:
