发生了JNI错误

Question

I built a GUI form through Intellij. I exported the app as an artifact to a JAR file. I opened the JAR on my personal computer and had no issues - the app appeared and fully functioned. I tried running it on someone else's computer, and when I clicked on the JAR file it said "Error: A JNI error has occurred, please check your installation and try again." After that box, it said "A Java Exception has occurred." I tried this on my laptop, and the JAR file properly opened.

I think it has to do with the JRE or JDK being necessary on a computer, but I do not know enough about Java to fix my problem. The computers I tried that it didn't work on either had JDK installed or not installed at all.

Suggestions?

Edit - I'm using Java 10. The other computer that it didn't work on had Java 8. I ran jar on the command, and the error is here - stack trace I guess the solution is update java? but then is there a way to force java 10 code to run on a java 8 computer?

Answer 1

I figured it out. I had to change the compiler on my app, and then, rebuild the artifact.

Change compiler: File -> Settings -> Build, Execution, Deployment -> Compiler -> Java Compiler
