Launching Eclipse 2020-09R error Version 11 or greater is required. [message #1833071]

Using the extraction from zip file and not the installer I get an error when launching the Eclipse software.
"Incompatible JVM Version 1.8.0_201 of the JVM is not suitable for this product. Version 11 or greater is required"
I've installed Java SE Development Kit 11 , 14, and 15 and continue to get the same error at launch. Each time I reboot and run java -version I see the version matches the last version installed:
Java version "15" 2020-09-15

Is there a config file that needs to be updated? Why does Eclipse not see the new version of java?

Hello

I have the same issue. The only thing that worked to me is to remove Eclipse manually and reinstall it, because in the first initialization after the installation it works. But when I close it, the next time I want to use it doesn't works.

I know this is an odd job and not a good solution. So, I hope if somebody more experienced can come and solve the problem in a "legit way".

If i find a good solution in other places I will come and post it, of course.

How do you uninstall it or install it? I've been using the zip file and extracting the Eclipse folder to C:\Program Files folder. In a cmd window I run java -version and it shows version 11 or whichever version I've installed. I have it band-aided for now by modifying the desktop shortcut to this:
"C:\Program Files\eclipse-2020-09R\eclipse.exe" -vm C:\progra~1\Java\jdk-11.0.8\bin\server\jvm.dll

But I'd like to figure out how to run it with out the switch.

If you used the installer, it would know that Java 11 is needed and would try find it in your system registry, so even if Java 8 is the default on the system, but you have Java 11 installed, the installer would find it and use it. The installer generates an installation where the eclipse.ini includes two lines like this before the -vmargs line in that file:

-vm
C:\Program Files\Java\jdk-11.0.5\bin

You can edit the eclipse.ini file to add this manually (or, if it's already present with an older version of Java, to change it).

Can the installer be made silent? This is for a programming class and the software will be pushed through SCCM if I can this sorted.
I tried the suggestions found on https://wiki.eclipse.org/Eclipse.ini#-vm_value:_Windows_Example. Modifying the ini file as you described and was described in the wiki did not change anything. But modifying the shortcut does work.

Side note, even when I tried the installer the version of Java never changed from 1.8 (as reported in java -version).

There is this bug open for a headless installer mode:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=487626

But everyone expects all software to be free and so no one is actually willing to fund anything.

Modifying the eclipse.ini most definitely works. The Eclipse Installer relies on this and I've done this a great many times to be able to assert that it most definitely work.

Using the Eclipse Installer won't change your default "java -version". When using the installer, you choose on the final page which Java version to use and if the version that you choose is not the default of the system, it will generate a -vm option in the eclipse.ini (and that definitely works because my system's default is Java 8 and yet I can create installations that use the Java 11 version also on my system).

BTW, I imagine it would be pretty easy to make a mistake editing the eclipse.ini. Each argument must be on a separate line, i.e., there is no parsing to break arguments on spaces. So even a trailing space on a line is going to end up being part of the argument passed to the process. So be sure that the -vm is on a line all by itself, without trailing spaces, and that the subsequent separate line is the path to your Java installation. And make sure it's before the -vmargs line in the eclipse.ini.

I stand (sit) corrected. I came into this knowing nothing and was being shown how to modify the file by a co-worker. We were trying to add the line at the bottom of the file. Once added above the -vmargs line it works fine. Thanks for the suggestion and hand holding.

Step 1: Installed the higher version of Java
Step 2: Navigate to bin folder of Java higher version
Step 3: Copy the path of Java bin folder as above step.
Step 4: In notepad, Open eclipse.ini from the eclipse folder (unzip)
Step 5: Add below text just above -vmargs,
-vm
path_of_Bin_folder\javaw.exe (e.g. C:\Program Files\Java\jdk-14.0.2\bin\javaw.exe)

Step 6: Save the notepad file

Step 7: Launch Eclipse 2020-09

Enjoy....!

IDE are supposed to be free... Not even Microsoft charges for their C family IDE, Visual Studios.

Can you paste or attach exactly what your eclipse.ini looks like after you tried?

I had that problem too, but it solved itself when I completely uninstalled Java, JDK, and then reinstalled everything.

My problem started after I installed jdk-8 after having a funtioning Eclipse install using jdk-15. I was able to solve the problem by using the "-vm" command line argument to point to the jdk-15\bin directory. My jdk-8 projects are still pointed to the correct JDK.
