Build errror in Eclipse

[defalt926]

Hi everyone!

I have just started to setup my Eclipse. I followed the instruction on this site:
https://github.com/dbeaver/dbeaver/wiki/Develop-in-Eclipse
But somehow I have a lots of errors when build. I don't know how to resolve this problem. I am a total beginner at Eclipse.
I am using OpenJDK11, and I am developing on Linux Mint. But similar errors occured on Win 10.
Here is a few of those:

Thank you for your help in advance.

Hi! In Project Explorer, open context menu with right-click on a node dbeaver -> plugins -> org.jkiss.dbeaver.model. In the popup window, choose Java Compiler -> Errors/Warnings. Open Deprecated and restricted API. Switch all combo boxes from Error to Warning, hit Apply and Close, recompile the app, and everything should be ok.
