R: rJava package install failing

Question

When installing rJava using the install.packages(\"rJava\") command I get the following error:

checking Java support in R... present:
interprete         


        

Answer 1

On Arch Linux, I needed to install openjdk-src to get a JNI path working.

In other words, these are the packages I needed to install before sudo R CMD javareconf ran successfully:

local/jdk-openjdk 14.0.2.u12-1
    OpenJDK Java 14 development kit
local/jre-openjdk 14.0.2.u12-1
    OpenJDK Java 14 full runtime environment
local/jre-openjdk-headless 14.0.2.u12-1
    OpenJDK Java 14 headless runtime environment
local/openjdk-src 14.0.2.u12-1
    OpenJDK Java 14 sources
