A common error in IntelliJ when attempting to run a new Java maven project is Error:java: release version 5 not supported.
Here are 3 techniques to resolve this. Try them in order. If one doesn't resolve the issue, try the next.
1. Update Java Compiler
Go to IntelliJ IDE menu item (or File on Windows) -> Preferences -> Build, Execution, Deployment -> Java Compiler
-
Delete value under Target bytecode version, then click OK
-
Refresh maven
Try running again. If problem persists, continue on to number 2 below
2. Update SDK Version
Go to File -> Project Structure -> Project Settings -> Project. Make sure you have the correct Java version selected. It should be the same as the one you downloaded
Also on this same panel, go to Platform Settings -> SDKs. Make sure you have the correct Java version selected
Click OK
-
Refresh maven
Try running again. If problem persists, continue on to number 3 below
3. Add property to pom.xml
Within IntelliJ, open pom.xml file
Add this section before
<dependencies>(If your file already has a<properties>section, just add the<maven.compiler...>lines below to that existing section):
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
Change the
xin1.8to your Java version. For example, if you’re using Java 13, change 1.8 to 1.13Refresh maven
- Try running again

By default, your "Project bytecode version isn't set in maven project.
It thinks that your current version is 5, so just go to "Project Settings>Build, Execution...>compiler>java compiler" and then change your bytecode version to your current java version.
Have a good day :)
This is what fixed mine. Thank you very much, sir.
Thank you so much, it totally worked for me.
There are many great answers here. If you imported your maven project from spring initializr, make sure the project is set to your your java version. In my case Java 16.
Goto File > Project Structure > Modules
Select the project folder, next change the Language level to your Java version, apply and click OK.
[Already Solved] Error:java: error: release version 5 not supported in IntelliJ IDEA Ultimate
The proper solution for maven-based projects is to change the target version as shown by Angie in option 3. I added some background on the root cause and provided an additional example for spring boot projects and "plain" java projects here:

None of Angie's steps worked for me but setting build plugin in POM file like below worked for me .
11
"
org.apache.maven.plugins
maven-compiler-plugin
3.8.1
11
"
Just a small hint. For JDK9+ you have to use
9or10etc. instead of1.Xcause1.Xdoes not exist for JDK9+.So for JDK13 you have to use
13instead of1.13...Thank you!
Thank you :)
very much helpful.
Thx Angie..... the third solution worked for me. Tried all of them but finally success with the third one. Thx
Thank you, Angie. New to Maven and new to IntelliJ; option 3 did it for me.
