I want to run java codes containing JavaFX pieces, in the sublime-text itself.
I am using JDK 13, and so JavaFX is not bundled with JDK itself. I downloaded the JavaFX files and stored them at E:\javafx-sdk-15.0.1, I also created a system environment variable PATH_TO_JAVAFX to store "E:\javafx-sdk-15.0.1\lib", the directory where JavaFX modules are present.
I tried to add the following build inside Sublime-Text 3, but it is not working.
{
"shell_cmd": "javac --module-path %PATH_TO_JAVAFX% --add-modules javafx.base,javafx.controls,javafx.fxml,javafx.graphics,javafx.media,javafx.swing,javafx.web \"${file}\"",
"file_regex": "^(..[^:]):([0-9]+):?([0-9]+)?:? (.)$",
"working_dir": "${file_path}",
"selector": "source.java",
"variants":
[
{
"name": "Run",
"shell_cmd": "javac --module-path %PATH_TO_JAVAFX% --add-modules javafx.base,javafx.controls,javafx.fxml,javafx.graphics,javafx.media,javafx.swing,javafx.web \"${file}\" && java --module-path %PATH_TO_JAVAFX% --add-modules javafx.base,javafx.controls,javafx.fxml,javafx.graphics,javafx.media,javafx.swing,javafx.web \"${file_path}/${file_base_name}\""
}
]
}
Running the same command in cmd itself with actual values of file, file_path and file_base_name, works smoothly. On inspection, I found %PATH_TO_JavaFX% is not doing what I expected it to, it is not expanding to the actual path I set it to.
Trying the same build with the actual value of PATH_TO_JAVAFX works for the normal compile, but the run version still doesn't work. I got the following error:
Error: Could not find or load main class D:\Codes\JAVA\HelloWorld_JavaFX.HelloWorld_JavaFX Caused by: java.lang.ClassNotFoundException: D:\Codes\JAVA\HelloWorld_JavaFX.HelloWorld_JavaFX
This is the code I am trying to run(taken from),
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class HelloWorld_JavaFX extends Application {
@Override
public void start(Stage stage) {
String javaVersion = System.getProperty("java.version");
String javafxVersion = System.getProperty("javafx.version");
Label l = new Label("Hello, JavaFX " + javafxVersion + ", running on Java " + javaVersion + ".");
Scene scene = new Scene(new StackPane(l), 640, 480);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch();
}
}
Where exactly is the issue, and how to solve it? Also is there a way, I can use the PATH_TO_JAVAFX, instead of writing the complete path?
NOTE: I am using Windows.
What I assumed to be an issue with Sublime-Text turns out to be Java issue only, which could have been resolved quickly with few Google searches if I had thought about that.
So, thanks to some enlightenment from this Stackoverflow thread and mostly hit and trial, I was able to build successfully inside Sublime Text only without any added plugin or modification to Sublime Text.
This is how my build file looks now
{
"shell_cmd": "javac --module-path %PATH_TO_JAVAFX% --add-modules javafx.base,javafx.controls,javafx.fxml,javafx.graphics,javafx.media,javafx.swing,javafx.web \"${file}\" && java -cp \"${file_path}\" --module-path %PATH_TO_JAVAFX% --add-modules javafx.base,javafx.controls,javafx.fxml,javafx.graphics,javafx.media,javafx.swing,javafx.web \"${file_base_name}\"",
"file_regex": "^(..[^:]):([0-9]+):?([0-9]+)?:? (.)$",
"working_dir": "${file_path}",
"selector": "source.java",
"variants":
[
{
"name": "Compile",
"shell_cmd": "javac --module-path %PATH_TO_JAVAFX% --add-modules javafx.base,javafx.controls,javafx.fxml,javafx.graphics,javafx.media,javafx.swing,javafx.web \"${file}\""
},
{
"name": "Run",
"shell_cmd": "java -cp \"${file_path}\" --module-path %PATH_TO_JAVAFX% --add-modules javafx.base,javafx.controls,javafx.fxml,javafx.graphics,javafx.media,javafx.swing,javafx.web \"${file_base_name}\""
}
]
}
Still can't find an easy way to get Environment Variable working, so have to add complete for path in place of %PATH_TO_JAVAFX%.
