I use IntelliJ IDEA as my development environment, and Maven for dependency management. I frequently build my project structure (directories, poms, etc) outside of IDEA and then import the project into IDEA using Import project from external model. This works great, except that in my poms I specify that the maven-compiler-plugin should use JDK 1.6, and when I import, IDEA informs me that the Language Level Changed and that Language level changes will take effect on project reload, and then prompts to reload the project. This is annoying because I always use the same JDK version.

How do I change the default JDK that IntelliJ IDEA uses, so that I don’t have to reload my project every time I import a new project?

This setting is changed in the «Structure for New Projects» dialog. Navigate to «File» -> «New Projects Setup» -> «Structure…»

Selecting Structure For New Projects

Next, modify the «Project SDK» and «Project Language Level» as appropriate.

Selecting Project Language Level

Previous versions of IntelliJ IDEA had this setting in «File» -> «Other Settings» -> «Default Project Structure…».

IntelliJ IDEA 12 had this setting in «Template Project Structure…» instead of «Default Project Structure…»

Download and unpack a JDK archive file (.tar.gz) and add it as a SDK in the ‘Project Structure’ dialog box ( Ctrl+Alt+Shift+S )

jdk 9 intellij

Also make sure to set an appropriate ‘Project language level’. I forgot to do that when creating the GIF.

Project Structure > Project > Project language level

For Java 8 set it to 8, for Java 9 set it to 9, and so on.

I have found out that in recent versions of IntelliJ IDEA requires Java 1.8 but is not configured by default.

We can change the path or configure from Project Settings > Project > Project SDK

here we can edit or add the JDK´s path.

(in my case the path is located in C:Program FilesJavajdk1.8.0_102)

Change JDK version to 1.8

  1. Language level File -> project Structure -> Modules -> Sources -> Language level -> 8-Lambdas, type annotations etc.
    enter image description here

  2. Project SDk File -> project Structure -> Project 1.8
    enter image description here

  3. Java compiler File -> Settings -> Build, Executions, Deployment -> Compiler -> Java compiler

One other place worth checking: Look in the pom.xml for your project, if you are using Maven compiler plugin, at the source/target config and make sure it is the desired version of Java. I found that I had 1.7 in the following; I changed it to 1.8 and then everything compiled correctly in IntelliJ. 

<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>
            <encoding>UTF-8</encoding>
        </configuration>
    </plugin>
</plugins>
</build>

The above responses were very useful, but after all settings, the project was running with the wrong version. Finally, I noticed that it can be also configured in the Dependencies window.

I am using IntelliJ 2020.3.1 and the File > Other Settings… menu option has disappeared. I went to Settings in the usual way and searched for «jdk». Under Build, Execution, Deployment > Build Tools > Maven > Importing I found the the setting that will solve my specific issue:
