rJava installation fails on macOS 10.14

Question

After upgrading to MacOS Mojave (10.14.1), I\'m no longer able to install rJava for R version 3.5.1 with Java version \"1.8.0_102\" installed.

I tried

Answer 1

After installing JDK 11.04 LTS I rain into the same error in R Studio on Mojave

R was expecting Library not loaded: /Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk

Despite running sudo R CMD javareconf the error still persisted

Therefore I browsed to /Library/Java/JavaVirtualMachines/ in finder and renamed the folder "jdk-11.0.4.jdk" to "jdk-11.0.1.jdk"

Restarted R and both library(rJava) and library(xlsx) now work.

Hope this helps someone
