I have searched the same error solution in here. I have tried and i get errors every time i have tried to add the attributes to the jfx-impl and the build file as suggested on here . I have came across a solution on net beans to clean re-build and the issue will solve its self but that is not working for me . I am currently using netbeans version 8.2. Please can any one provide a simple updated solution please that is easy to follow. I have tried several different suggestions before submitting my issue
The errors are below
Detected JavaFX Ant API version 1.3
Launching <fx:jar> task from C:\Program Files\Java\jdk1.8.0_261\jre\..\lib\ant-javafx.jar
Warning: From JDK7u25 the Codebase manifest attribute should be used to restrict JAR repurposing.

BUILD FAILED (total time: 1 second)
Update---
I have carried out further investigation, the error is related to "no main manifest attribute, in jar file " i think . I found a suggested solution that Main-Class need to be a configured path but did not demonstrated how and what to exactly .
Here is my MANIFEST.MF
Manifest-Version: 1.0
Implementation-Title: UserModelApplication
X-COMMENT: Main-Class will be added automatically by build
Implementation-Version: 1.0
Permissions: sandbox
Codebase: *
JavaFX-Version: 8.0
Class-Path:
Created-By: JavaFX Packager
Implementation-Vendor: aaaa
Main-Class: usermodelapplication.UserModelApplication
I have been currently working on this issue for a long time now , Please provide me a clear work around . I am tempted to install net beans 8.0 as the attributes are already added.
I have tried all the latest versions of java , still receive the same issue . it was recommended to use latest versions to run JavaFx smoothly still receive issue
