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

Question

While running Selenium 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
• IDE: Eclipse Oxygen
• Firefox Version: 46

Answer 1

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

Answer 2

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.

Side bar

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#?

Answer 3

你可以试试这个方法

javac --release 8 yourClass.java

Answer 4

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

That screenshot stolen from the Jetbrains issue as well

Answer 5

53 stands for java-9, so it means that whatever class you have has been compiled with javac-9 and you try to run it with jre-8 . Either re-compile that class with javac-8 or use the jre-9

Answer 6

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 .

Answer 7

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.

Answer 8

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.

Answer 9

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.

Answer 10

The solution for me was doing what Andrei Ku.netsov said at https://youtrack.jetbrains.com/issue/IDEA-251407/Failed-to-run-Android-project-in-the-Idea-20203-EAP-OutputBuildAction-has-been-compiled-by-a-more-recent-version-of-the-Java , summarized in the following image:

"Root cause: IDEA sources are now compiled against Java 11. Known workaround is to configure Java 11 as a Gradle JVM." (Andrei Ku.netsov)

Answer 11

You should check your Project Facets.

Project Properties > Project Facets

Change java version to the same version you are using. That work for me!

Answer 12

IDE : Eclipse 2021-09

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.

---

Now your code should be executed properly.

Answer 13

转到 Project 部分，单击 properties > 然后到 Java compiler > check compiler compliance level is 1.8 ，否则底部不应有黄色警告

Answer 14

刷新 gradle 依赖项对我有用：右键单击项目 -> Gradle -> 刷新 Gradle 项目。

Answer 15

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.

Answer 16

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 :

1. 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)

2. Project Structure -> Project Settings -> Project :

3. Project Structure -> Project Settings -> Modules :

4. 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 .

Answer 17

If you're using IntelliJ IDEA and having this error, try this.

1. Command +, (Open Preferences)
2. Build, Execution, Deployment > Build Tools > Gradle
3. Gradle JVM > Change it to a proper version

I had Java v11 installed on the Sonarcube server, but the error is saying its the Build Agent that doesn't have Java v11.

I decided to add the Java v12 bin path to the Environment Variable Path for it to be detected. IMPORTANT THIS NEEDS TO BE DONE ON THE BUILD AGENT:

For a Hosted Build Agent you can install JDK v11 or use this PowerShell script step:

- task: PowerShell@2
  displayName: 'Download and Install Java v11'
  inputs:
    targetType: 'inline'
    script: |
      [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
      $Command = "c:\jdk-11.0.15_windows-x64_bin.exe"
      $Parms = "/s"
      Write-Host [System.IO.File]::Exists($Command)
      if ([System.IO.File]::Exists($Command)) {
        Write-Host 'Downloading Java11.exe'      
        Invoke-WebRequest https://yourOwnUrl.com/jdk-11.0.15_windows-x64_bin.exe -OutFile $Command
      }
      Write-Host [System.IO.File]::Exists($Command)
      & "$Command" $Prms
      [System.Environment]::SetEnvironmentVariable("JAVA_HOME", "C:\Program Files\Java\jdk-11.0.15")
      [System.Environment]::SetEnvironmentVariable("Path", [System.Environment]::GetEnvironmentVariable('Path', [System.EnvironmentVariableTarget]::Machine) + ";$($env:JAVA_HOME)\bin")

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.

Answer 21

In build.gradle(app) update as below: (Worked for me)

 kotlinOptions {
        jvmTarget = '1.8'
    }

Answer 22

For me this problem was resolved by just installing older version of testng. Looks like It compiles with my Java 8

Faced the same issue when initialise my project from spring initizer We need to match the version of java used for run and compile in "build.gradle.kt" file as shown below:

Answer 26

In my case, I use the IntellJ Idea and set JDK11 as my SDK and JDK17 in gradle setting.

Just update my SDK as JDK17, it was solved

Check the JDK in "Project Setting"(CMD+;) -> SDK

with

the gradle JVM in "Preference"(CMD+,) -> Build Tools -> gradle JVM

For Android Studio, File -> Project Structure [Ctrl + Alt + Shift + S]

Answer 29

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.

Answer 30

it looks like everyone is using windows for development, but if you use Linux, lower your Java version. maybe install JDK 8, the version table provided by @Nithin should give you an idea of which version you want to install.

Answer 31

After configuring the version of the compiler to 1.8 (your required version), try the older version of spring boot currently it is 3.0.0 by default but you can try 2.7.6 instead.
