Idea, a workaround found when a Java syntax is not supported in a lower version

For example, in a project, prepare to use the java.util.objects#equals syntax, found that the hint version is not supported.

F4 View the configuration of module, it turns out to be version 1.6.

When I manually modified to 1.8, I was prompted: module is the Java version in Maven configuration.

So, to the Pom file, it is found that the default starter of spring boot is Java 1.6.

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.9.RELEASE</version>
</parent>

So I tried to add it in my own child pom:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
    <java.encoding>UTF-8</java.encoding>
</properties>
To overwrite the default starter configuration.
And then it's OK.
