Hello all !

I am using:
- Windows 10 64 bit
- Eclipse 2018-09 (4.9.0) Build id: 20180917-1800
- openjdk-11.0.1_windows-x64_bin.zip which I unzip and included under Installed JREs Preferences.
- Eclipse is running using jdk-10.0.2_windows-x64_bin.exe .
- I installed "Java 11 Support for Eclipse 2018-09" based on information from the market place
( http://marketplace.eclipse.org/content/java-11-support-eclipse-2018-09-49 )
I installed from http://download.eclipse.org/eclipse/updates/4.9-P-builds

Using openjfx.io/openjfx-docs/#maven as a reference I created a maven project with:

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.target>11</maven.compiler.target>
<maven.compiler.source>11</maven.compiler.source>
</properties>

Under <dependencies> I have:

<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-controls</artifactId>
<version>11</version>
</dependency>

I copied openjfx.io/openjfx-docs/HelloFX.java and it compiled with no problems .

The project does not use module-info.java !!!

When I try to run it I am getting:
Error: JavaFX runtime components are missing, and are required to run this application

This is odd since the compile went ok.

Next just for testing I created a Runnable JAR . I used "Package required libraries into generated JAR"

Since my JDK 11 is not included in my system path environment variable I created a shortcut (Windows) to the jar:

Target: C:\Java\jdk_11\bin\javaw.exe -jar java_11_tests.jar

Statrt in: K:\JavaAPPs\Java_11_Tests

I was VERY surprise to see that the program is working !!!

Can some one explain why I could not run the program in the IDE and run it as a Runnable JAR ?

Is something missing in Eclipse to support java FX 11 ?

I prefer not to use module-info.java for the time being.

Do you have openjfx-11 jars on the classpath of Eclipse Project ?

OpenJDK-11 does not include javafx anymore, it comes as standalone.

Thanks for the response.

I am aware that javaFX 11 is a stand alone now.

If you look at my post you will see that:

- The project is Maven and I have the dependency needed.

- The code is compiled with no problem.

- a Runnable JAR is working !!! it containes the javaFX jars
index.php/fa/34195/0/

- I get the message in the IDE when I use the regular run configuration
index.php/fa/34196/0/

Regards.

Perhaps s.t. is not good in that launch configuration.
Luckily, the launch configuration dialog now has a button "Show Command Line" that shows you, how Eclipse is invoking your program. From there it should be easy to figure what is missing.

Thanks for the response.

This is the "Show Command Line" output.

The FX stuff is there....

But there is new development.

When I generate file module-info.java
index.php/fa/34207/0/

I have

It is working !!!!

Also the -p is added (--module-path)

index.php/fa/34209/0/
