Starting this program with 'java -jar minoritytranslate-1.14-beta.jar' in Linux gives this error:

[main] INFO ee.translate.keeleleek.mtapplication.MinorityTranslate - Starting application [main] ERROR ee.translate.keeleleek.mtapplication.MinorityTranslate - Application failure: java.lang.NoClassDefFoundError: javafx/application/Application at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:763) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:467) at java.net.URLClassLoader.access$100(URLClassLoader.java:73) at java.net.URLClassLoader$1.run(URLClassLoader.java:368) at java.net.URLClassLoader$1.run(URLClassLoader.java:362) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:361) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at ee.translate.keeleleek.mtapplication.MinorityTranslate.main(MinorityTranslate.java:39) Caused by: java.lang.ClassNotFoundException: javafx.application.Application at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 13 more

What is the solution to this error?

MinorityTranslate requires JavaFX to function, which is not included with openjdk. Try installing openjfx package.

The openjfx package is relatively new and I haven't tested it yet. I will take a look this weekend (I don't have access to my VMs right now).

You can also try using the binary version of MT, which includes JavaFX.

Oracle JDK will also work.
