Unable to use aracne.jar executable

[gspirito]

Hello, I've build the jar with ant main as indicated with no errors (openjdk version "1.8.0_212"), but if I run java -jar ./aracne.jar I get this error:

Exception in thread "main" java.lang.NullPointerException
at java.io.File.(File.java:277)
at aracne.Aracne.main(Unknown Source)

What is the cause of that?

Thank you in advance.

Hi, this is actually the expected behavior. Unfortunately, the current version of ARACNe doesn't have a help menu by default. You can invoke it by java -jar ./aracne.jar -h.

Thank you!

The error is caused by the source file format.

java -jar ./aracne.jar

Do you what the issue is exactly because when I type in java -jar ./aracne.jar it gives me the same error and tells me nothing new
Exception in thread "main" java.lang.NullPointerException
at java.io.File.(File.java:277)
at aracne.Aracne.main(Unknown Source)
Can someone explain me what does this mean?

You need to supply the argument -h, please see above answer.

java -jar ./aracne.jar -h

Unknown option '-h'
