I tried installing Jenkins with JDK 11 on a Linux server, and now I'm trying to add the Selenium (Grid) plugin.
I managed to get it to work on Jenkins with JDK8, but after upgrading to JDK 11, the plugin says Accept Time out, and the setting to access the grid on the right in Jenkin's menu disappeared.
I can't find a documentation saying it isn't compatible with JDK11, as on their page it says it requires java 1.8 or later.
*Note: I also tried a fresh installation with JDK 11 directly, but I got the same result.
I'm a little late, but for those who read it later. Selenium plugin is not compatible with java 11. You have to use java 8.

I've spent too much time trying to find how to do this with. Tips for setting up a dev environment are what I am asking for, however I will start with what I tried so far.
As I understand JavaFX was separated from the JDK after JDK 8, however, for an R&D project, I need to create JavaFX applications that can be built and compiled in Java 11. Normally installing the e(fx)clipse plugins into Eclipse will not work unless a Java 8 installation is pointed to.
So, I have been following this guide: https://gist.github.com/stevenliebregt/bc62a382fc43064136b662ee62172ab3
JavaFX 11 is on LTS from Gluon, it seems, meaning I'd have to pay at least $900 to get it.
So instead, I tried building OpenJFX using following the instructions at this link:
https://wiki.openjdk.org/display/OpenJFX/Building+OpenJFX
When I start the build with Gradle, it fails because the minimum supported version for Java to build this is apparently 17.
Any suggestions for building JavaFX projects with JDK 11 is greatly appreciated.
The LTS version is JavaFX 11.0.16. You can download non-LTS 11.x versions from GluonHQ by checking the "include older versions" checkbox on the download page.
Once you clicked it, you see all versions starting with 11 until 20-ea+1, even the obsolete ones.
Your best choice is probably 11.0.2
And to add something you didn't ask for: JDK 11 is compatible with the latest versions of JavaFX, even JavaFX 18, as you can see in the Release Notes:
"As of JDK 11 the JavaFX modules are delivered separately from the
JDK. These release notes cover the standalone JavaFX 18 release.
JavaFX 18 requires JDK 11 or later."
(I emphasized the last part of the quote)
Thanks all, for the good information. I found that the best way to handle this way to build in IntelliJ instead. I can build and run JavaFX 18 easily with JDK 11.
I've been trying for a while now to get JDeveloper to use the latest JDK (17.0.1). I've searched around and the answers I've found have all said to change "SetJavaHome" in either jdev.conf or product.conf. I've tried both and both times when I tried to run JDeveloper it gave me a popup saying:
"You are attempting to run with Java 17.0.1
Running this product is supported with a minimum Java version of 1.8 and a maximum version less than 1.9.
Update SetJavaHome in
C:\Users\sudoc\AppData\Roaming\JDeveloper\12.2.1.4.0\product.conf to point to another Java.
This product will not be supported, and may not run correctly if you proceed.
Continue anyway?"
Since 1.8 is so far below 17, I feel like I might be trying to change the wrong thing. Any ideas? I'm running windows 11 and I just installed JDeveloper yesterday, so it should be the latest version.
Is there any compelling reason that you need to use JDeveloper? Otherwise, there are other options such as IntelliJ IDEA (community version) which is great for Java.
JDK 1.8 has passed a test of time and its very common to use that but jdk 17 is latest version and this version has not passed test of time so its better to use 1.8 or maybe jdk 11 is good too.
*Due to some project requirements I "have" to use eclipse 4.18 (2020-12) which uses Java 11 by default and is mandatory to start.
But my entire project is/was written in Java 1.7 earlier. Now , in my mac i have both java 1.8 and 11 installed also my eclipse settings are such shown below.
I have made sure removed all java 11 references in my eclipse and made the project and workspace configure to take the 1.8 jdk and run at 1.7 compiler level.*
but when i run ,project -->clean-->build, i run into the JaxB missing in java 11 ( in java 11 JAXB was removed and my project uses jaxB extensively) This is known.
So i am wondering what am i missing that my projects are still building my project with java 11 and not java 1.7 (using jdk 1.8 configured).
Please help.. stuck on this since some days.

If Eclipse itself is being run with Java 11, and you have a plug-in installed that has not been properly update to work under Java 11, as it appears, you will need an updated version of that plug-in. Update to the latest "oracle design studio", and if you still see this problem, contact Oracle support.
The latest Eclipse may require Java 11 to run, but it's simple to set up Eclipse projects that use older Java versions. Don't mess with the Java version it uses to start up, as long as that is a proper Java 11 version.
As one commenter mentions, you'll have to have a particular Java distribution configured in "Installed JREs->Execution Environments", and then you'll have to have the project configured to use that Java version symbol, like "JavaSE-1.7".
I had java version 8 previous and my eclipse worked just fine. But now I have java version 7 and I can't open eclipse on my computer. What should I do? please help.
I think there are two options:
Upgrade to Java version 8 (or newer).
If you can't do that, downgrade to a version of eclipse that supports Java 7. eclipse 4.5 (Mars) (or earlier as noted on the linked page), as of eclipse 4.6 (Neon) Java 8 is required.
I feel I should note that newer versions of Java (and eclipse) can still target Java 7 (and many earlier versions).
But now I have java version 7 and I can't open eclipse on my computer. What should I do?
Use versions that work together. When you for example look at your second screen shot, it says something like "requiredJavaVersion=1.8" or so.
In other words: you can't just come in and run eclipse with any version of java.
The other answer gives you the required details.
And a final note here: in case you tried to start eclipse with that older JVM in order to "allow" to ensure that eclipse won't allow "java 8" stuff in a project: that isn't the right way then. Instead: eclipse allows you to "define" JDKs to be used for your project. So you can easily tell eclipse: "I have a Java7 jdk sitting here, please use that for project X".
You do not need to run eclipse itself with a Java7 JVM in order to use a Java7 JDK for an eclipse project!
There will be a file under the Eclipse installation directory named as eclipse.ini.
It will launch the eclipse for that specific jdf and you can change the path to your jdk7.
Hope it helps.
It depends basically on which version of the eclipse you have.
If you have eclipse 4.6(Neon) or the latest version, then you must need a newer JDK version of Java (>=1.8 which you need to download). Or If you want to roll back to an older version of Eclipse then consider downloading eclipse 4.5(Mars).
Or If you have an eclipse version of 4.5(Mars) or older then see in eclipse.ini
-Dosgi.requiredJavaVersion = 1.8 and change it to -Dosgi.requiredJavaVersion = 1.7 which can be found in the folder containing eclipse.exe file.
I followed the answer given here:
https://stackoverflow.com/a/27647491/5904193 to install Netbeans ide 8.2 with jdk 10.0.2 on windows 10 64 bits OS.
After installation, I found that the jdk was generally incompatible with the ide. So I finally got the latest Netbeans version 9.1 from Apache.
This works with my jdk so I decided to clean things up by uninstalling Netbeans 8.2. Attempting to uninstall directly with the uninstall executable fails with the same error as the installer. That is it requests jdk 8 or higher (I have only jdk 10 installed).
I then tried using the jar file trick by extracting the Uninstaller and executing the jar file with Java. Things happened (lots of output in the console screen and uninstall actually completed) but all the program files remain, I can still see the program in Programs and Features and I could even start the app using the desktop shortcut that was not even touched by the uninstall.
I suspect I could uninstall it normally if I installed jdk 8. But, I mean, there has to be a way to uninstall it without jdk 8 after being able to install without that jdk. Thanks.
"But, I mean, there has to be a way to uninstall it without jdk 8
after being able to install without that jdk."
There is no reason that should be true since you did not did not meet the "required software" standard for NetBeans 8.2, which states "Java SE 8 is required to install and run NetBeans IDE 8.2", nor did you follow the standard installation process.
So you "installed" NetBeans 8.2, but not successfully. Since it wasn't installed properly it's not surprising that the uninstall process is failing.
After installation, I found that the jdk was generally incompatible
with the ide.
That's because:
You didn't install NetBeans properly.
Regardless of that, NetBeans 8.2 does not support the use of any JDK > 8.
I suspect I could uninstall it normally if I installed jdk 8.
Perhaps, and unfortunately I think that is what you need to try. However, since you chose not to follow the normal NetBeans 8.2 installation process don't be too surprised if you still have problems.
