I wanted to try Java 19 and have easy switching back to the Java 17 that I have already installed.
So, I installed sdkman but it knows nothing of the previous Java.
Found the "install local" command, used it to link the java 17 location to a unique name and sdkman seems happy, as it reports "Done installing!".
After that the "sdk current java" returns "Not using any version of java".
So then I tried "sdk use java [my unique name]. That was also accepted.
But still the "sdk current java" response is unchanged.
Have I misunderstood how this should work? I want to be sure sdkman knows what is there already before I add another Java.
Thanks for your advice!

OK, I should have tried harder.
I installed Java 19 with sdkman then the command "sdk default java [my old version]" switches back as required.

i haven't done anything yet, i can't find any problem similar to this on google
It was the JDK version
Inside netbeans when i clicked on Start to start the server, it says something about JDK 11, netbeans has a feature that let's you download many open JDK versions, i downloaded a random openJDK8 version and it worked
I don't know how to edit the JDK version manually or from any other IDE though, but my (video) class is using netbeans so for now i'm ok (they didn't teach on video because the video is 2 years old so it's outdated)
as Apple announced that Xcode Cloud is now available for all developers, I tried to set it up for a Kotlin Multiplatform project. The start was a little bit hard tbh. Currently I am facing following problem during a simple test action:
The operation couldn’t be completed. Unable to locate a Java Runtime.
Please visit http://www.java.com for information on installing Java.
Command PhaseScriptExecution failed with a nonzero exit code
So I tried to install a jdk during the ci_post_clone.sh phase. The output of java -version after the installation on the Xcode Cloud is the following:

also ./gradlew -v output:

Nevertheless, I still get the same error. Is this maybe a restriction by Apple?
Any ideas?
I'm trying to set up flutter on my Ubuntu 19.10 machine.
When I run flutter doctor --android-licenses It prompts me to update the SDK like so -
A newer version of the Android SDK is required. To update, run:
/home/<username>/Android/SDK/tools/bin/sdkmanager --update
When I run it, I encounter an Exception - java.lang.NoClassDefFoundError
This answer suggests changing DEFAULT_JVM_OPTS in sdkmanager to
DEFAULT_JVM_OPTS='"-Dcom.android.sdklib.toolsdir=$APP_HOME" --add-modules java.xml.bind'
This seems to work in Java 9/10. However, I use Java 11 and unfortunately the java.xml.bind module and java.se.ee module has been discontinued from Java 11 -
java version "11.0.6" 2020-01-14 LTS

Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.6+8-LTS, mixed mode)
Is there a way to fix this in Java 11? Or do I have to downgrade to Java 9/10?
flutter supports java 1.8
so, try install java 1.8
Hi I am trying to run javaws but it prompts:
To open this Web Start application you need to download the Java Runtime Environment.
I am sure JRE is installed, maybe javaws does not find it, how do I fix that?

Java Web Start (javaws) was deprecated in Java 9 and removed in Java 11.
As you are using java 13, you can either downgrade from 13 to 8, or look for alternatives.
Perhaps an alternative such as https://openwebstart.com/ can help you out with that.
P.S: In case you're using tools to manage version such as sdkman or such, there might be the case where it's also not available in SDKs # version 8 provided by sdkman.

I feel like I've installed everything possible - jre, jdk, dfk, openadk,....and nothing works. Is there a guaranteed solution to make java work?
Try it with java 8 SDK or versions before it, Not after this version.
