IntelliJ JavaFX 12工件：没有主要的清单属性，但它有吗？

Question

Little confused here. Looked around and haven't found anything. Lots of people seem to be having similar problems but I haven't seen a solution yet.

I cloned the IntelliJ gradle non-moduler hellofx sample application from here .

Builds and runs okay, good.

I then tried to build an artifact. I did Add -> JAR -> from modules with dependencies...

Resulting in:

Building the artifact and trying to run it gives me the following error:

"C:\\Program Files\\Java\\jdk-11.0.2\\bin\\java.exe" -Dfile.encoding=windows-1252 -jar E:\\hellofx\\out\\artifacts\\hellofx_main_jar\\hellofx_main.jar no main manifest attribute, in E:\\hellofx\\out\\artifacts\\hellofx_main_jar\\hellofx_main.jar

But the Main-Class attribute is in the manifest file that was generated when building the artifact:

Answer 1

Fixed it with help from Jose's answer here .

I had to add the native libs from the bin folder from javaFX.

I had to take extra steps because building with gradle wasn't putting the fxml and class files together in the build. So I had to add this to my build.gradle:

plugins {
  //...
  id 'idea'
}

sourceSets.main.output.resourcesDir = "build/classes/java/main"

idea {
    module.outputDir file("out/production/classes")
}

In addition I had to move the META-INF folder into the resource folder so when building it was placed in the correct location.
