This would need to be added to https://github.com/eclipse/eclipse.jdt.ls first. Could you create an issue there?

I had raised the issue eclipse-jdtls/eclipse.jdt.ls#1892.
Thank you for replied and your work really awesome.

Hi @mfussenegger, I had followed the instruction at eclipse-jdtls/eclipse.jdt.ls#1892 (comment) and it worked.

But I have a question that can we handle this with this plugin because I don't want to add that line every time to every project. Would you like to add this line to the global setting?

Thank you.

This seemed to work for me, however: the code-action doesn't seem to work, when the class extends another class implementing Serializable. The warning will show up, same as the code action, but nothing will be generated.

If it works for a simpler case it is likely a eclipse.jdt.ls bug and you'd need to open an issue there in order for it to get fixed.
