How to protect the jar files from reverse engineers

[Bahar Çağlar]

Hi,

I have a jira plugin, and I want to put it to marketplace. (paid via atlassian)

There is a field in the form of listing the add-on: Binary URL

I put my jar file to an address. But I do not want to anyone to extract my "example.jar" file and access my source.

Thanks in advance

1/ First, compile your code with -g:none (to eliminate debug info)

and

2/ Second, you can obfuscate your code using an obfuscator

Keep in mind that you cannot completely hide your code. You can only make the attempts to reverse engineer the code harder, that's all.

This is why I would advise against it. If you have a bug, the stack trace will point to the obfuscated code, which is painful to determine in real code.
