Unless nobody has it you can have fun to deobfuscate it
The post was checked and we had not found any reason to believe its unsafe aka Its safe to use but not 100% possible well cause its obfuscated
The jar scan you had sent proves nothing and i would not recommend trusting the result since its mostly the same as Virustotal
Dynamic checking is the most useful method to verify if something is safe in such a case ( possible infections can hide but 99.99% get found )
