The import javafx cannot be resolved

Question

I installed Eclipse IDE today on my Ubuntu Linux and then installed JavaFX using 'Install New Software' and when I created a javafx project, I got the following error in Main.java:

The import javafx cannot be resolved.

So, I listed the following directory to search for "jfxrt.jar":

ls -l /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext

But I didn't find "jfxrt.jar".

java -version

The output:

openjdk version "1.8.0_45-internal"

OpenJDK Runtime Environment (build 1.8.0_45-internal-b14)

OpenJDK 64-Bit Server VM (build 25.45-b02, mixed mode)

Answer 1

According to the packages list in Ubuntu Vivid there is a package named openjfx. This should be a candidate for what you're looking for:

JavaFX/OpenJFX 8 - Rich client application platform for Java

You can install it via:

sudo apt-get install openjfx

It provides the following JAR files to the OpenJDK installation on Ubuntu systems:

/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/jfxswt.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/ant-javafx.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/javafx-mx.jar

Hope this helps.
