I have just installed the support package for java 11 support for Eclopse Photon, and after Right-clik on the project -> Build Path -> Configure Build Path -> Java Compiler from left menu -> Use default compliance settings = 11 it worked!
A big thanks to the kids at Eclipse, special to the most senior kids.

It does not work as expected, since I installed it I get several errors about "The type Exception is not visible" and "The type StringBuilder is not visible", and many more.

Don't work in Eclipse 2018-09 final
"Eclipse PDE Patch with Java 11 support for 2018-09 development stream" is not applicable to the current configuration and will not be installed.

For all who get an error regarding "Eclipse PDE Patch ...":

PDE is not included in some Eclipse Packages. To work around this issue, you may try to

  1. Install "Eclipse Plug-in Development Environment" from from the built-in update site
  2. Then install this Marketplace Entry
