I am new to Kotlin and still do not understand everything. I am trying to build a project in .jar but so far without success. I found many many solutions and tried all of them
Invalid signature file digest for Manifest main attributes w/ Jetty and Maven Shade Plugin
"Invalid signature file" when attempting to run a .jar
Valid JAR signature for JavaFX projects
but every time the same error pops up:
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

Please forgive me my ignorance and treat with understanding. Thanks =)
Changes:
assembled jar with such a command:
jar cvmf src/main/kotlin/META-INF/MANIFEST.MF Application.jar -C target/classes io/lavr/utils/any2json
Then I tried to run:
java -jar Application.jar
but I have error again:
Error: Unable to initialize main class io.lavr.utils.any2json.ApplicationKt
Caused by: java.lang.NoClassDefFoundError: kotlin/TypeCastException
