I'm using GluonHQ's JavaFX to create mobile applications for Android. I'm using OpenJDK 8 and OpenJFX 8.
asus@asus-pc:~/Dokument/Eclipse-Workspace/Deeplearning2C$ java -version
openjdk version "1.8.0_222"
OpenJDK Runtime Environment (build 1.8.0_222-8u222-b10-1ubuntu1~19.04.1-b10)
OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)
asus@asus-pc:~/Dokument/Eclipse-Workspace/Deeplearning2C$
When I generate a android application, I write this command.
asus@asus-pc:~/Dokument/Eclipse-Workspace/Deeplearning2C$ ./gradlew android
But I get this error. I don't understand what it is and I have never got that before.

According to this question, the suggestions in the answer was was:
- (The easiest solution, but not suitable for most of the applications) Change your minSdkVersion to 21.
- Shrink your application code. This was discussed many times previously (see here and here).
- If none of the above solutions work for you, you can try to use my workaround for this issue - I'm patching the Android gradle plugin to not include Activity classes in main dex. It's a bit hacky, but works well for me.
Too many classes in --main-dex-list, main dex capacity exceeded
My project is very minimal and I don't use many dependencies at all. So I cannot shrink down my code. That's is impossible for me. I cannot change the SDK version because I'm running at the lowest Java 8 version. The last suggestion I don't want to try because I don't like "quick hacks" for projects.
Do you think it has something with Deeplearning4J dependency?
My gradle.build file looks like this:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'org.javafxports:jfxmobile-plugin:1.3.17'
}
}
apply plugin: 'org.javafxports.jfxmobile'
repositories {
jcenter()
maven {
url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
}
}
mainClassName = 'se.danielmartensson.Main'
dependencies {
compile 'com.gluonhq:charm:5.0.2'
compile group: 'org.deeplearning4j', name: 'deeplearning4j-core', version: '1.0.0-beta4'

compile group: 'org.datavec', name: 'datavec-api', version: '1.0.0-beta4'
compile group: 'org.projectlombok', name: 'lombok', version: '1.18.8'
}
jfxmobile {
downConfig {
version = '3.8.6'
// Do not edit the line below. Use Gluon Mobile Settings in your project context menu instead
plugins 'display', 'lifecycle', 'statusbar', 'storage'
}
android {
manifest = 'src/android/AndroidManifest.xml'
}
ios {
infoPList = file('src/ios/Default-Info.plist')
forceLinkClasses = [
'se.danielmartensson.**.*',
'com.gluonhq.**.*',
'javax.annotations.**.*',
'javax.inject.**.*',
'javax.json.**.*',
'org.glassfish.json.**.*'
]
}
}

Edit:
I tried to compile gradle.build file with dexOptions . Se below and the error too.

> warning: Ignoring InnerClasses attribute for an anonymous inner class
(EDU.oswego.cs.dl.util.concurrent.FutureResult$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.
