I am developing a Javafx application and its ready for the build. In order to read and write excel files I,m using org.apache.commons.compress library (a jar file), which has a main class named Lister in it. Where as, my application has its own MainApp class file (essential for a Javafx application). So, while I'm building the application, the build is successful and a jar file of my application is also generated but I am getting this error :
The jar libs\commons-compress-1.18.jar has a main class
org.apache.commons.compress.archivers.
Lister that does not match the declared main org.dracul.tree.MainApp
Bundler EXE Installer skipped because of a configuration problem: Main application jar is missing.
This means that there are two main files inside my jar.
Secondly, when I'm running executable jar of my application, it crashes.
You can specify main class when creating the jar, by adding class name as MyClass:
java -cp myjar.jar MyClass
