Whenever i run the gradle task bootBuildImage, GraalVM JDK is downloaded for every new project as the console states below:
Downloading from
https://github.com/graalvm/graalvm-ce-builds/releases/download/vm-21.1.0/graalvm-ce-java11-linux-amd64-21.1.0.tar.gz
How can i set an offline GraalVM JDK for every new project?
You can use「SDKMAN」to resolve your question.
Command is:
export JAVA_HOME=$HOME/.sdkman/candidates/java/21.0.0.r8-grl
The SDKMAN is a command tool to switch the java enviroment.

I have a spring boot application where the gradle version is 7.0.
I had to change my openjdk 16 to openjdk 11 because I want to use keycloak with the project.
After I updated the Path, my java 11 gets recognized:
But my gradle is still stuck on the other version:
Edit: I have noticed that the error is in my build.gradle file:
Things I have tried:
restarting my pc
deleting cache folders for vscode
putting a JAVA_HOME into my path and link it and reverted it(I checked everytime with a new powershell window to make sure that it has updated and it always worked)
test another spring project (The other spring boot app does not have this gradle issue)
Anything else I can try?
I would look closely at the other spring boot app that does not have this gradle issue. VSCode has a habit of keeping cached versions of files around, but really you want the gradle files to be interrupted so it downloads new dependencies. I would look into that next, if you can't figure out what makes your other project work and this one not.
I have a JavaFX project I am working on using Gradle. What version of java is used when I use the gradle run task from the application plugin?
In IntelliJ I can go into the Gradle settings and change the "Gradle JVM" to any version I want. Is this just the version of java that is used to run the build? Or is this also the version that my application will be run on?
Where does my JAVA_HOME come into this, if at all?
Irrespective of IDEs, Gradle will use whatever language level of the JVM that is running Gradle. Typically whatever the value is for JAVA_HOME.
See Environment variables and Targeting a specific Java version
The new way to do it as of Gradle 6.7 is to use Toolchains for JVM projects
Your IDE should respect whatever Gradle configuration that is configured.
I am trying deploy my Spring Boot application to Elastic Beanstalk.
The problem that I am facing right now is, my application is developed with Tomcat 9, Java 13 and Project Facet 4.0.
So when I deployed to a AWS environment, I kept getting error. After researching, I found out AWS only support Tomcat 8, Java 8 and Project Facet 3.0.
I managed to change Project Facet 4.0 to 3.0.
But I can't add Java 8 to the project.
I downloaded the JDK 8 from Oracle, and tried open jdk-8u251-macosx-x64.dmg and run JDK 8 Update 251.pkg.
The system keeps giving me error that: "JDK 8 Update 251.pkg" can't be opened because Apple cannot check it for malicious software. This software needs to be updated.
Anyone know how to fix this problem so that I can run JRE 8 on eclipse?
Here is picture the problem that I have when I deploy the app to AWS.
An internal error occurred during: Updating AWS Elastic Beanstalk environment
Here is the thread that I tried to follow but without success:
https://github.com/aws/aws-toolkit-eclipse/issues/149.
Can you elaborate where exactly are you seeing the error? While running the JDK package or while configuration the JDK within Eclipse?
Nevertheless, I suppose your main requirement is to get your Eclipse to use Java 8.
It can be done in multiple ways.
Usually you can change Java compiler level to 1.8 from Project Settings even if you're using Java 13.
If you're using Maven, you can specify compiler source and target to Java 1.8
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
Alternatively, you can download the JDK 8 zip instead of installer, unzip to any location and use that in Window > Preferences > Java > Installed JREs. Be sure to mark that one as default JRE.
We have a server that runs Sonar and previously only had Java 6 installed and everything worked fine. We now have a Java 7 project and are encountering the "Unsupported major.minor version 51.0" version when the Maven surefire plugin tries to analyze the project.
Is there a way to specify the Java version sonar should use for a specific project?
Java 7 is already installed on the server.
Thanks in advance!
Never mind found the JDK option under Advanced in the Jenkins configuration for the job.
I created a dynamic web project in eclipse for a web service with axis2. I then converted it into Maven project, I'm able to compile and generate war file in eclipse, but when i deploy it on server and try to build it with Hudson-3.0.0 it gives me following error:
mojoFailed org.apache.maven.plugins:maven-compiler-plugin:2.3.2(default-compile)
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project WebServices: Compilation failure
Unable to locate the Javac Compiler in:

Please ensure you are using JDK 1.4 or above and
not a JRE (the com.sun.tools.javac.Main class is required).
Please Let me know what's wrong with it!
I have exactly the same problem, ever since I upgraded Hudson from 2.2.1 to 3.0.1.
Both JAVA_HOME environment variable and JDK in hudson configuration point to JDK and not to JRE.
If I run mvn compile in the workspace directory of the job, everything works well.
Looks like the hudson cannot find java_home.
In hudson settings java.home property is set correctly ?
Does any other java projects builds successfully ?
Did you do what the exception said yet?
Please ensure you are using JDK 1.4 or above and
not a JRE (the com.sun.tools.javac.Main class is required).
Sounds like you don't have Java installed. So install it.
