Trying to start Grakn but getting a Java error

I'm trying to start Grakn with ./grakn server start in the console. I'm in the grakn directory but I'm getting the error below:

An error has occurred during boot-up. Please run 'grakn server status' or check the logs located under the 'logs' directory.
Unsupported Java version [11] found. Grakn needs Java 1.8 in order to run.

Grakn uses Java 8 whereas you have Java 11. You can fix this by installing the JDK for Java 8, you should be able to find it for your system here.

Then, you need to make sure Java 8 can be found. On mac/unix:

export JAVA_HOME=`/usr/libexec/java_home -v 1.8
