Modify IntelliJ idea to create a MAVEN project default Java Language

When you create a MAVEN project using IntelliJ idea, the default Java language is 1.5, although it can be modified in Project Structrue, but each time the Pom.xml file changes, the project is reset to version 1.5.

You can resolve this issue by adding the following configuration to the Pom.xml file. 1.8 of these are configured according to the actual situation

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>


or join the following configuration.

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>
