IntelliJ - What indicates that a module is compiling in the Java version indicated in the POM

Question

Using a multi-module Maven project configured in IntelliJ IDEA, I am configuring version 1.8 in the maven-compiler-plugin in the parent POM version. But I am configuring 1.5 in a certain child module.

In the parent:

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

In the child:

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

        </plugin>
    </plugins>
</build>

In Eclipse, I had this indicator:

How and/or where do we check that in IntelliJ IDEA? How do I know that the child module is compiling with the desired 1.5 Java version?

See the related answer for the relevant screenshots.

You can find the source version in the Project Structure dialog, Modules, Sources tab: Language level.

Target version is in File | Settings | Build, Execution, Deployment | Compiler | Java Compiler (Per-module bytecode version).
