Generated JAR file - JNI error has occurred

I am using the IntelliJ IDEA to create a jar artifact from a LeanFT project.

The jar artifact was generated, but with the following error message:

JNI error has occurred, please check your installation and try again

when trying to execute the jar file directly.

It is working when I use the IDE for execution. No arguments or parameter values are required. I am getting the same error when I generate a jar file from a simple "Hello World".

Stack trace:

Solution

  • I looked into the exception you got : Invalid signature file digest for Manifest main attributes.

    Are you using signed jar files as dependencies of your project? If so, when you generate a jar containing the dependencies, then try to execute it - the JVM detects your generated jar as a manipulation of the signed jars you are using.

    Here is a list of questions where this exception was encountered:

    Follow the links above and find the exact solution which will help you. The solution depends on what exactly you are doing, deployment-wise (specifics of how you are creating your jar artifact).
