I want to elevate the source compiler version to 1.7 how to do that in eclipse?

Answer 1

In your pom.xml look for the blurb

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.5</source>
        <target>1.5</target>
    </configuration>
</plugin>

and change accordingly.

Cheers,
