I do not know, to be honest. I just Googled “how to install OpenJDK on Linux” and looked for a credible-looking source. Thinking about it, it might be that indeed that is only the JRE (given the extension) and therefore will not contain the extra stuff.
Later I’ll do some more research and see if I can help figure out how to use OpenJDK for development with Godot.
Summary of the following Longtext (every paragraph after this one is the actual Longtext): I figured out how to install OpenJDK 11 (not 8). I installed the headess one. Now I only need to know where the OpenJDK Jarsigner is and how to configure the Debug-Keystore.
Today I went looking for ,,how to install openjdk", this time I forgot the ,,on linux" extension.
I found this snippet in the description of the third search result:
If you want to develop Java programs then install the openjdk-7-jdk package.
So I tried sudo apt-get install openjdk-8-jdk in my terminal, with this result:
Paket openjdk-8-jdk can not be found.
Then I tried installing just openjdk-8, this package can also not be found.
Finally, I found Openjdk-11-jdk and Openjdk-11-jdk-headlesswhen browsing the application manager.
I installed the headless variant, because headless just means "without Graphical User Interface".
Now I only need to know where the OpenJDK-Jarsigner is and how to configure the Debug-Keystore before I can export my game to my Android phone,
