Class has been compiled by a more recent version of the Java Environment

Question

While running a script, I am getting the following error message in the Eclipse console:

Class has been compiled by a more recent version of the Java Environment (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0.

Java Version: 8

class file version 53 = Java 9. Your Java 8 JVM cannot execute Java 9 code. — howlger, Nov 23 '17 at 13:53

This is just a version mismatch. You have compiled your code using java version 9 and your current JRE is version 8. Try upgrading your JRE to 9.

49 = Java 5
50 = Java 6
51 = Java 7
52 = Java 8
53 = Java 9
54 = Java 10
55 = Java 11
56 = Java 12
57 = Java 13
58 = Java 14
59 = Java 15
60 = Java 16
61 = Java 17
62 = Java 18
63 = Java 19
64 = Java 20
65 = Java 21

giving advice on the *logical* choice might not be a good solution at all... what if the project is run with jre-8 in the first place and someone accidentally compiled some module against 9? – Eugene Nov 23 '17 at 14:11
I believe the upgrade still won't cause any troubles since there won't be any backward compatibility issues. And it was logical since i believe the compiler has got upgraded to the latest version. – Haagenti Nov 23 '17 at 14:15

you're thinking in terms of a small, sandbox project; for enterprise projects - this is never a easy shift. For example some bugs were fixed in 8 for generics that you were relying on side-effects of them in 7; or `HashMap` order has changed from 7 to 8... etc. I have faced this. *Simply* saying - move to 9 is a good option, but never a simple and fast one – Eugene Nov 23 '17 at 14:18

if you're stating in terms of enterprise project levels, yes you are correct and I strongly agree with that point. Upgrading/downgrading is never a most viable option in such scenarios. – Haagenti Nov 23 '17 at 14:27

When I run java -version, I see JDK and JRE both as 1.8.0 . Also in project -> properties-> Java compiler1.8 is there for compliance, Source compatibility, Generated .class files. Also, in Java build Path-> Libraries: JRE System Library [Java SE-1.8] is there. Still I get error: "Caused by: java.lang.UnsupportedClassVersionError: org/springframework/nativex/NativeListener has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0" .

You might see this error in IntelliJ as well and this comes up in Google.

I think it's a Gradle error more than an IDE error.

The fix (stolen from here) is configure Java 11 as a Gradle JVM in IntelliJ:

File -> Settings -> Build, Execution & Development -> Build Tools -> Gradle and change Gradle JVM to 11

IDE: Eclipse Oxygen.3

To temporarily correct the problem do the following:

Project menu > Properties > Java Compiler > Compiler compliance level > 1.8

A permanent fix likely involves installing JDK 9.

FYI 1.8 is what Java 8 is called.

I recently returned to Java after a foray into C# (a breath of fresh air) and installed Eclipse Oxygen onto a clean system that had never had Java installed on it before. This default everything with a brand new install of Eclipse Oxygen yet somehow or other Eclipse can't get its own parameters to match the jdk that's installed. This is the second project I created and the second time I ran into this headache. Time to go back to C#?

For temporary solution just right click on Project => Properties => Java compiler => over there please select compiler compliance level 1.8 => .class compatibility 1.8 => source compatibility 1.8.

Then your code will start to execute on version 1.8.

I had a similar issue from the console after building a Jar in Intellij. Using the Java configuration to update to a newer version (Windows -> Configure Java -> Update -> Update Now) didn't work and stuck at version 1.8 (Java 8).

To switch to a more recent version locally I had to install the Java 15 JDK from https://www.oracle.com/uk/java/technologies/javase-jdk15-downloads.html and add that to my Java runtime environment settings.

I've reproduced on Windows 10 the similar issue in format like:

Error: LinkageError occurred while loading main class ...
java.lang.UnsupportedClassVersionError: com/.../ServiceApplication 
has been compiled by a more recent version of the Java Runtime (class file version 62.0), 
this version of the Java Runtime only recognizes class file versions up to 61.0

after upgrading the project from Java 17 to Java 18.

I had project settings regarding to Java 18:

Command line:

java version "18.0.1.1" 2022-04-22
Java(TM) SE Runtime Environment (build 18.0.1.1+2-6)
Java HotSpot(TM) 64-Bit Server VM (build 18.0.1.1+2-6, mixed mode, sharing)

Project Structure -> Project Settings -> Project:

Project Structure -> Project Settings -> Modules:

Project Structure -> Platform Settings -> SDKs:

And the reason of this issue was:

I forgot to specify the correct version for Run/Debug Configurations -> Build and run to Java 18 instead of Java 17:

As it was compiled with a newer Java version, but running on the older one.

If it's Maven-related issue, you can modify POM by specifying the -source and -target of the Java Compiler.

Your JDK version: Java 8
Your JRE version: Java 9

Here your JRE version is different than the JDK version that's the case. Here you can compile all the java classes using JDK version 1.8. If you want to compile only one java class just change the *.java into <yourclassname>.java

javac -source 1.8 -target 1.8  *.java

source: The version that your source code requires to compile.
target: The oldest JRE version you want to support.

Hi, this command is not working from any folder in the project. It says, "javac file not found: *.java" – Anish Mittal Nov 03 '22 at 02:12

I'm writing this because I found the other answers hard to understand.

Essentially your JRE is not updated and/or Eclipse is not configured to use the most recent JRE.

On Windows, go to Control Panel -> Programs -> Java -> update and proceed to update java

or if you don't have Java, go to Oracle's website and download the most recent JRE.

Once this is done, go into eclipse, and under the project view, right click on your project, select Java Build Path, double click on JRE System Library, then Select Workspace Default JRE 14.1.

If a recent version of Java doesn't show up here, it probably isn't installed. Check you JRE(NOT JDK) version and make sure it's recent. If it is, try restarting the computer then trying this again.

This is caused because you have compiled the code with java version 9 and have java8 installed. You don't have to update to solve this issue.

Right click on project > properties > Java Compiler > untick-Enable project specific settings > configure workspace settings > tick-Use default compliance settings > Apply and Close.

I faced this error in Intellij. Apparently, choosing java 1.8 as the project SDK doesn't affect the javac compiler that's used to build the project.

To change that, go to Settings -> Build, Execution, Deployment -> Compiler -> Java Compiler, and change Project bytecode version to 8.

My error was similar: " UnsupportedClassVersionError: Class has been compiled by a more recent version of the Java Runtime"

Solution: I tried to update my JAVA version from 15 to 17 and it worked in my case rather than updating all JRE in the compiler or doing other things.

Simply download the updated version of JAVA and change the path in SYSTEM Variable to 17

Go back to the project and apply the below steps :

In my case, I'm building with VS2019 some C++ code that is using ANTLR4. ANTLR4 is java based, and to use it I run java commands as a custom build step.

Earlier that day I had updated my JRE (Java Runtime Environment) on my new laptop to 1.8. Not thinking, since it's been a year since I ran ANTLR4 stuff... I need the full JDK to COMPILE with java. So I had a 1.8 RUNTIME, but the VS2019 build shell was finding the JDK1.7 compiler. Once I installed the 1.8 JDK, all was good.

So 80% of the time JRE is fine for me... it's just when I need the full JDK, DOH I need the full JDK.

Last week, I updated my Mac's Android Studio from 2021.2.1 to 2021.3.1. Then our project was built failed for the similar reason:

Cause: com/android/tools/idea/gradle/run/OutputBuildAction has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 53.0

I found several discussion on the Jetbrains YouTrack Forum: Failed to run Android project in the Idea 2020.3 EAP (OutputBuildAction has been compiled by a more recent version of the Java Runtime (class file version 55.0)). The suggested workaround is to update the defined Gradle JDK version to JDK11, but many Android projects don't support Gradle JDK11, so does mine.

Another solution is to downgrade Android Studio from 2021.3.1 to 2021.2.1, and it worked for me. Hope it helps.
