I’m trying to set up a java project to use openjdk-11 and all the answers I have found so far have me going in circles. I’m using ubuntu 20.04, so I used the command ‘sudo apt install openjdk-11-jre’. The installation seemed to be successful but now I can’t seem to figure out the file path to the installed JRE.
I thought it would be under /user/lib/jvm/java-11-openjdk-amd64 somewhere. When I point eclipse to that location and try to search for a JRE however it doesn’t find anything.
I have found lots of examples with info on how to install but nothing about how to track down the exact file path.
Any help would be greatly appreciated.
Update While I was able to find the JRE location, the root problem turns out to be eclipse. I forgot I had an older version (4.6) open since that is what the project was originally using. Once I switched over to 4.18 I was able to add the java 11 JRE.

Using which will give you /usr/bin/java which won’t help as it will be a symlink. You need something like
readlink -f $(which java)
