A JavaFX application that uses the Californium libraries to act as coap-client to discover and interact with coap-servers.
Unfortunately javaFX was only a short time part of the java-JRE/JDK releases, mainly for oracle's java 1.7 and java 1.8. For openjdk's and since java 11 it's required to be installed as separate SDK, specific to the java-JRE/JDK used.
See JavaFX/openJFX for general information around JavaFX. Downloads are available from Gluon - Downloads. For Windows, download the windows SDK, e.g. Gluon - Windows 64 bit, 17.0.2 or an other version/variant listed at that download page.
Unzip the content of the downloaded zip into <path>. The --module-path must then contain <path>\javafx-sdk-17.0.2\lib.
For Ubuntu or other linux distributions, there are also packages available.
sudo apt install openjfxNote:
Using different versions of java and javafx may fail, ensure you use a proper pair.
Prebuild jars are available from the Eclipse Repository.
Eclipse Repository - cf-browser-3.6.0.jar
Additional experimental TCP/TLS support (copy it to the same folder as the cf-browser-3.6.0.jar): Eclipse Repository - cf-cli-tcp-netty-3.6.0.jar
oracle-jdk-8 or openjdk-11:
Just use mvn to build it, as usual.
mvn clean installUsing openjdk-8 instead of oracle-jdk-8 requires to install openjfx-8 ahead. See Stackoverflow
sudo apt install \
openjfx=8u161-b12-1ubuntu2 \

libopenjfx-jnito prevent further updates, though the current recommended version is for java 11.
Note: if openjfx was marked to hold the java 8 version, updating to java 11 requires to mark the above modules with unhold and update & upgrade them to the java 11 version.
java-8:
java -jar cf-browser-3.6.0.jarjava-11 (module-path of Ubuntu 18.04):
java --module-path /usr/share/openjfx/lib --add-modules javafx.controls,javafx.fxml -jar cf-browser-3.6.0.jarNote: If openjfx has been downloaded and installed manually, adapt the --module-path to
<path>/javafx-sdk-???/lib.
Alternatively, when using Java 11 or later, the application can be started from the source folder using
