When I try to download my kepler engine using cmd, I face this problem for the ant in the build.xml. I install the java, ant, and svn versions, and I don't have any problems.

The Kepler FAQ "system requirements" explicitly states:
Kepler is a large application that has substantial hardware requirements.
These include 512MB of RAM (1 GB or more recommended), at least 300 MB of disk space, and at least a 2GHz CPU. Kepler runs on modern Windows, Macintosh (OS X), and Linux systems using Java 1.8 or greater.
As explained here, you error message means you are not using the right JDK. (JDK8 or more)
Check out Instructions and Overview of the Kepler Build System. / Assumptions
You are running Java 1.8. To test this assumption type: "java -version"
You are using Ant 1.8.2. To test this assumption type: "ant -version"
You have installed Maven 3.0.3 or newer. To test this assumption: "mvn --version"
You have installed an SVN client, v1.6. To test this assumption type: "svn --version"
For development with Eclipse these have been tested with Eclipse Ganymede and SVN 1.5.5,
with Subclipse 1.4.7.

I have built my app with JavaFX 11 and now I need to distribute it. I have chosen to distribute it in two ways: cross-platform fat-jar (I know, I know, it is discouraged, but that is not the point) and platform specific image created with jlink.
I am building on Linux Mint 20.1. I am using Maven and creating runtime image with javafx-maven-plugin. I have JDKs for both platforms on my Linux machine and pointed to the corresponding jmods folder in pom.xml.
The built fat-jar works on both Linux and Windows where both have installed the latest Java SDK (11.0.12).
The image for Linux also works without problems.
However, the image for Windows does not run and the output of -Dprism.verbose=true is this:

I got the same response when I tried to run the project from source on Windows. (I copied the project to Windows, installed maven, and it would not even run with javafx:run, let alone jlink with javafx:jlink)
I have tried many links on Google and none of them works, People either have something missing in their installation (I have everything installed at least as far as I have found) or the issue pops up in a different situation (when packaging a fat-jar for example, or running their application from IDE).
What I have not tried so far is creating the image by hand from command line, since I have read many times that it is discourage compared to using a build tool like Maven.
What can I try next?
java.lang.UnsatisfiedLinkError: no prism_sw in java.library.path
Means you're definitely missing some dlls from your library path, although this could only be a part of the problem.
When you download javafx sdk for windows from this link, you get a zip with the following structure:
The bin folder contains all the natives you need to run JavaFx (on windows, or the platform you downloaded the sdk for)
Note that you don't always need all the natives, jfxwebkit.dll for example is only needed when you work with javafx-web.
You need to extract them somewhere and add the folder you extracted them in to the library path when you run the java program
java "-Djava.library.path=path_to_natives" -classpath "your_classpath" <Your main class>
I have managed to solve this. The javafx-maven-plugin expects in <jModsPath> a colon separated list of paths to ALL jmods, not just the standard oridinary JDK. It pulls what's missing out of maven repository I think but ignores all platform clasifiers.
When I run my project I get the following errors. My jdk is currently 1.8. To fix it, I have tried resetting the jdk, downgrading to 1.7, I've checked my buildpaths, I've gone into preferences and restored to defaults and it's the same error. I've deleted and reinstalled the jdk as well.
In regards to the error about JavaLaunchHelper I found a question on here that said it's a bug that isn't fixed in 1.8 and that it can be ignored as they are actually in the right place.
My IDE is Spring Tool Suite and I'm writing in Spring Data.
Any help is appreciated, thanks!

The class io/pivotal/ticket/RuleControllerTest has been compiled using Java 1.8, but you are trying to run it using Java 1.7 (or earlier). You should check your run config. Since this is being run from Eclipse's test runner, you need to either change the run config for that or run Eclipse using JDK 1.8.

The following indicates that the JDK you are running with is not able to load classes compiled with JDK 7: Unsupported major.minor version 51.0
Check the JDK used by Intellij in the menu 'IntelliJ => About IntelliJ Idea'.
SonarLint for IntelliJ 2.2 requires JDK >= 7. Also note that upcoming new versions will probably require JDK >= 8.
To change the JVM that intellij Uses by default refer https://intellij-support.jetbrains.com/entries/23455956-Selecting-the-JDK-version-the-IDE-will-run-under.
You can Update /Applications/IntelliJ\ IDEA\ 14\ CE.app/Contents/Info.plist
and replace JVMVersion 1.6* with 1.8*

I have encountered the same problem, but on Mac.
I have solved it by updating my Java from 1.7 to 1.8!
In this video, it says that before installing the RoboVM plugin, you should do some configurations, in particular choose Java 1.8 for JDK.
Also, here is the link to the same problem on RoboVM Google Group!

One month ago this was working fine, but now I have resumed the example and it does not work. I reinstalled Orion CB in mi VM but I didn't change anything in Tomcat.
Could you help me? Thank you.
Maven 3.3.3 is only compatible with Java 7+, and it seems that you are trying to run it with Java 6. Please check your JAVA_HOME environment variable, it should point to a Java 7 JDK.
