Please suggest me what should I do?

Answer

Add two properties to specify the version of Java you want to target. Currently, it’s defaulting to 5 (which is no longer supported). For example,

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>
