adoptium.net VS download-jdk

1.18 requires Java 17. (Java link if you need it)

Note: In order for JarFix to work, you needed add all options when installing Java (Picture).

Did you actually install a Java Development Kit? Because this sounds like you only installed a text editor. You can download it here: https://adoptium.net/ (download the latest version for your OS and install it)

Try this https://adoptium.net/

Make sure you have Java fully installed (select all components when installing). Link to Java download if you need it: (Link)

if you downloaded Java from adoptopenjdk/adoptium/temurin/whatever they call it now, you do have it.

I had the same issue and I fixed it with downloading openjdk 17. you can download it here https://adoptium.net/

Which was recently rebranded as Eclipse Temurin

if they are using Windows, have them reinstall java https://adoptium.net/

e.g https://adoptium.net/

There are plenty of vendors providing builds of OpenJDK free to use in production including Oracle themselves. Oracle's build of OpenJDK that is free to use in production is found here: https://jdk.java.net.

Java can also be found in OpenJDK. Download your version, extract it (usually, the default directory is /usr/lib/jvm), and point the java program.

As someone else has mentioned, Oracle JDK still has limitations when used in commercial applications. However, there are lots of JDKs that are free to use for anything you want to do with it. jdk.java.net is where I used to get mine from. If you want an installer adoptium.net is also great (that's the JDK provided by the Eclipse foundation).

Java.com is the website for the product Java. Oracle owns java as mentioned in 1 so it makes sense they would have java-related things on their website. jdk.java.net is the domain for the Oracle OpenJDK

This, the oracle JDK from oracle.com.. Not the Oracle build of the JDK from http://jdk.java.net/ which has always been free.

https://jdk.java.net/ is probably the most standard as those are the build from openjdk itself. The eclipse temurn is a different Openjdk build by a different organization.

OpenJDK is an open-source project. The key word there is 'source'. OpenJDK does not provide binary distributions. Yes, there is one available from jdk.java.net but that is the Oracle OpenJDK JDK.
