Not a java dev touching java for the first time, can't get gradle to work.
I'm trying to install this extension for Ghidra. The readme says I should run:
GHIDRA_INSTALL_DIR=${GHIDRA_HOME} gradle
I've installed java 18 and gradle on a mac. When running the above, I get the following error:
Starting a Gradle Daemon (subsequent builds will be faster)
> Task :copyDependencies NO-SOURCE
> Task :compileJava FAILED
/home/gradle/project/src/main/java/ghidra/app/plugin/core/analysis/eBPFSolanaAnalyzer.java:156: error: text blocks are not supported in -source 11
func.setComment("""
^
(use -source 15 or higher to enable text blocks)
1 error
FAILURE: Build failed with an exception.
Tried running out of docker too (thinking it was a problem with my installation):
docker run --rm -u gradle -e GHIDRA_INSTALL_DIR=/home/gradle/project/installed -v "$PWD":/home/gradle/project -w /home/gradle/project gradle gradle
But alas get the exact same error.
Why does gradle think I have Java 11 when in fact I have java 18? gradle -v gives me:

Gradle 7.4.2

Revision: 540473b8118064efcc264694cbcaa4b677f61041
Kotlin: 1.5.31
Groovy: 3.0.9
Ant: Apache Ant(TM) version 1.10.11 compiled on July 10 2021
JVM: 18.0.1.1 (Homebrew 18.0.1.1+0)
OS: Mac OS X 12.4 x86_64
This is probably total newb question but like I said I've never touched java:) Any help super appreciated.
The error means that the project has been configured to be compatible with Java 11, which is why you can't use features from newer versions (even if you run with a newer version).
While I don't know the Ghidra project, you can see from the build file in the extension that it applies a script from the base project:
apply from: new File(ghidraInstallDir).getCanonicalPath() + "/support/buildExtension.gradle"
Then, if you head over to the Ghidra project and find the extension file, you can see that it indeed configures the source and target version:
compileJava {
sourceCompatibility = ghidraProps.getProperty('application.java.compiler')
targetCompatibility = ghidraProps.getProperty('application.java.compiler')
dependsOn copyDependencies
}
These appear to come from the properties file located in Ghidra/application.properties:
application.name=Ghidra
application.version=10.2
application.release.name=DEV
application.layout.version=1
application.gradle.min=6.8
application.java.min=11
application.java.max=
application.java.compiler=11
So I would imaging that if you find this file in your local installation, you can change the application.java.compiler property to 18. Just be aware that Ghidra might not not actually support it - or it might work just fine; try it out :)
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
IDE: Eclipse Oxygen
Firefox Version: 46
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
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#?

has been compiled by a more recent version of the Java Runtime (class file version 53.0)
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
That screenshot stolen from the Jetbrains issue as well
You can try this way
javac --release 8 yourClass.java
For Android Studio, File -> Project Structure [Ctrl + Alt + Shift + S]
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
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.
The solution for me was doing what Andrei Kuznetsov 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 Kuznetsov)
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.
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.
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.
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.
Additional helpful links:
Setting the Java Version in Maven
Consuming Jar Artifact of a Specific Java Version
Go to Project section, click on properties > then to Java compiler > check compiler compliance level is 1.8 , or there should be no yellow warning at bottom
Refreshing gradle dependencies works for me: Right click over the project -> Gradle -> Refresh Gradle Project.
You should check your Project Facets.
Project Properties > Project Facets
Change java version to the same version you are using. That work for me!
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.
If you're using IntelliJ IDEA and having this error, try this.
Command + , (Open Preferences)
Build, Execution, Deployment > Build Tools > Gradle
Gradle JVM > Change it to a proper version
This is getting as an example
if your computer running on an older version of java and the Neo4J is compiled on the latest version, please try to install the same version or upper to your computer.

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:

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.
In build.gradle(app) update as below: (Worked for me)
kotlinOptions {
jvmTarget = '1.8'
}
For me this problem was resolved by just installing older version of testng. Looks like It compiles with my Java 8
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
Check the version of Java configured in IDE by navigating to Settings -> Build, Execution, Deployment > Build Tools > Gradle
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
Faced the same issue when initialise my project from spring initizer
We need to match the version of java.sourceCompatibility and jvmTarget used for run and compile in "build.gradle.kt" file.
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.
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.
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.

but I can not find gradle home.
echo $GRADLE_HOME

the first step to determine home directory is detect location of gradle instruction:
which gradle
/usr/local/bin/gradle
there is incomprehensible bash file.
Any ideas how to detect gradle home directory via terminal?
You can use command:
brew info gradle
As the result you will have something like this:

Here, on the line 4 you can see the home path : /usr/local/Cellar/gradle/3.4
You can retrieve the path for GRADLE_HOME automatically using the following snippet in your .bashrc or .zshrc:
export GRADLE_HOME=$(brew info gradle | grep /usr/local/Cellar/gradle | awk '{print $1}')
This is handy when the path to Gradle's home changes, when Gradle is updated.
On Mojave (v10.14), Gradle v5.4, I had to append libexec after Gradle version for IntelliJ to work.

In eclipse go to platform - build.xml - right click on it - go to run as - external tools configuration - go to jre tab - add in separate jre the required jre version - add the build.xml file again to ant and run it
check this one
try this instead, adding java version in util.xml under platfrom folder. worked for me!
