I work on java project in eclipse using javafx and java-9 but i got an error:
Error: JavaFX runtime components are missing, and are required to run this application
I have installed:
java-9-openjdk.x86_64
java-9-openjdk-devel-9.0.4.11-4.fc27.x86_64
openjfx-8.0.152-12.b04.fc27.x86_64
openjfx-devel-8.0.152-12.b04.fc27.x86_64
I tried removing and installing these libs again using yum and also from .rpm packages but it didn't solve that problem.
In eclipse I specified build path in project like on screen here:
Eclipse Build Path
I tried to fix it by adding external jars: ant-java.jar, javafx-mx.jar, packager.jar but this didn't solve the issue.
My version of eclipse is Eclipse Oxygen.2 Release (4.7.2) and i got e(fx)clipse 3.0.0 . My kernel is: Linux 4.15.9-300.fc27.x86_64 I have no problem on Win 10 but i really want to work on my Fedora. I spent huge amount of time but I didn't find the solution.
I am not a Linux user but I wonder how java-9... and openjfx-8... are supposed to go together. They are just incompatible versions. You will have to find a Java distro which already contains JavaFX like the Oracle JDKs.
Update:
You find the latest version including JavaFX here:

I had some problems with JRE versions, so I tried to change it using the plugin Choose Runtime. I changed it to Java 1.8.0_112-release-287-b2. Now, when trying to start IntelliJ, i get an unsupported Java version error: Cannot start under Java 1.8.0_112-release-287-b2: Java 11 or later is required. I have tried to modify the runtime path in the ide64.exe.jdk file, but it seems like the old jdk IntelliJ ran on has been deleted. I also tried reinstalling intellij, no luck either. Anyone know how to get back the JDK? do I just download it from oracle and install it in the IdeaIC2020.3\jdks\ folder?
Thanks,
Jakob
I went to the jdks folder and deleted all contents. This fixed the issue. IntelliJ started without a problem.
I have a new MBP (16" 2019). Downloaded a fresh copy of IntelliJ IDEA Ultimate 2020.1.1. Used SDKMan to install Java 11-zulu and latest Gradle, 6.4. Went to File->New-Project and chose Gradle. When it loads, I get a Sync error and gradle won't process in IntelliJ correctly. Everything works fine from the CLI. I tried with importing an existing gradle project, different Java and Gradle versions, all give the same vague error.
idea.log
Caused by:
org.gradle.launcher.daemon.client.DaemonConnectionException: The newly
created daemon process has a different context than expected. It won't
be possible to reconnect to this daemon. Context mismatch: Java home
is different.
I've seen other questions about this but none of those solutions are working for me and I've never had this issue before, 10 years of using IDEA on OSX.
The issue is likely caused by the incorrect Java home path specified for the JDK in IntelliJ IDEA. Make sure it points to the correct location like this:
/Users/rob/.sdkman/candidates/java/14.0.1-zulu/zulu-14.jdk/Contents/Home
On macOS /Contents/Home part of the path is significant.
If some one are using macos with Sdkman use this version: sdk install java 8.0.322-librca for sdk 1.8 or other correlated version from librca, because sdk fom zulu i always had this same problema in intellij idea with java/kotlin and gradlew...
I have searched but not found any detailed information about it. In http://www.oracle.com/technetwork/java/javafx/downloads/index.html it says
As of JDK 7u6 JavaFX is included with the standard JDK and JRE bundles
But I am getting error on compile the code includes javafx.* packages. The packages are not founding. I am using Oracle JDK 10.0.2 and Intellij Idea 2018.2. Code is worked after I added the $JAVA8_HOME/jre/lib/ext/jfxrt.jar as library.
But the strange thing is I am able to build the code to target bytecode version 8 without adding the jar file from JDK 8 as above.
So the question is
How can I get the latest JavaFX?
Is the latest JavaFX is in the JDK 8?
UPDATE
JDK 10 includes JavaFX and compiled and ran successfully in command line. There is a problem with Intellij IDEA 2018.2. It does not recognize the JavaFX packages.
The error message in Intellij:
Error:(3, 26) java: package javafx.application does not exist
Note: There is no error while coding in editor (Not underling red). Error occurs when compiling in Intellij.
Updated question title.
JavaFX is included in Oracle JDK up to and including Java 10. From Java 11 onwards it will not be included anymore but can be downloaded separately here http://jdk.java.net/openjfx/ .
Additional information on how to get started with JavaFX from version 11 onwards is also available here: http://docs.gluonhq.com/javafx11/ .
Problem solved with this step:
Set the Project byte code version to 10 instead of 8 in
File > Settings > Build, Execution, Deployment > Compiler > Java Compiler
Thanks for helps.
I'm doing a Java project which involves JavaFX. I'm using Eclipse Oxygen with Java 8 (java-8-openjdk-amd64) and I installed the Eclipse plugin e(fx)clipse.
I don't understand why this project has two errors:
The project was not built since its build path is incomplete. Cannot find the class file for javafx.geometry.Point2D. Fix the build path then try building this project
and
The type javafx.geometry.Point2D cannot be resolved. It is indirectly referenced from required .class files
I searched on StackOverflow for similar problems, and tried some settings changes but nothing solved my problem.
I tried to change the access rules in the Build Path of my project: Build Path > Configure Build Path > Libraries > JRE System Library > Add a new rule
I added different rules: javafx/**, changed it to **/javafx/** but nothing changed.
This project works well in Windows, I opened it with Eclipse on Windows and everything works fine.
Do you have an idea on how to solve this problem?
EDIT: Accepted answer: $ sudo apt install openjfx
It looks like you haven't installed JavaFX. Because some parts of JavaFX are not compatible with the distributions open source licenses, it often is not part of the packages shipped by default.
If you're using Ubuntu, you can install it using sudo apt install openjfx.
For further reading have a look at JavaFX and OpenJDK.
I just read How to have Eclipse use JDK8 to compile a project?
What i added jdk8 to eclipse as,
From the answers of How to have Eclipse use JDK8 to compile a project?
I tried to Update the JDT/Core, JDT/UI bundles from http://dist.springsource.com/snapshot/TOOLS/java8/e43
But it shows error as,
"Eclipse Java Development Tools Patch for Java 8 Support (BETA)" is not applicable to the current configuration and will not be installed.
"Eclipse Plug-in Development Environment Patch for Java 8 Support (BETA)" is not applicable to the current configuration and will not be installed.
How Can i fix it ?
I can say that Java 1.8 does in fact work with Eclipse Luna ( the beta version released around March 17, 2014) or later. I tried it and it was good.
Also, I noticed that in the Eclipse Marketplace, there are now plugins to install functionality into Kepler to support JDK1.8. I haven't tried the plugin myself though.
This is a old topic but I just wanted to point out that I have searched enough to find that Indigo version can't be updated to S.E 1.8 here the link which is given on eclipse website to update the Execution Environment but if you try it will throw error for Indigo.
Here is the link where the Information about execution environment is given.
This shows the step by step to update Execution environment.
I have tried to update Execution environment and I got the same error.
