setup_r5() function does not run.

[adelfave]

Hi there,

Brief description of the problem:

Whenever I try to run the function: setup_r5(), I receive the following error: "Error in setup_r5(data_path = data_path) :
This package requires the Java SE Development Kit 11.
Please update your Java installation. The jdk 11 can be downloaded from either:

• openjdk: https://jdk.java.net/java-se-ri/11
• oracle: https://www.oracle.com/java/technologies/javase-jdk11-downloads.html"
  I have already downloaded the jdk 11, but I still keep receiving this error. I am wondering how to fix this issue so that I can at least run the sample data that you have provided in the package for a tutorial. I have asked Stack Overflow and none of their solutions have worked for me.

Reproducible example here

# insert reproducible example here

library(r5r)

# build transport network
data_path <- system.file("extdata/poa", package = "r5r")
r5r_core <- setup_r5(data_path = data_path, temp_dir = TRUE) # This is the part in your tutorial that provides me with the error.

# load origin/destination points
points <- read.csv(file.path(data_path, "poa_hexgrid.csv"))

Hi. Thanks for opening this issue. If you read the output of r5r::r5r_sitrep(), you will see that R is not detectiong you Java JDK v11, bus instead it detects v21.

$java_version
[1] "21.0.2"

The easiest solution here would be to install the dev version of {r5r}, which uses JDK 21. You can do this with the code below. Please let me know if this works for you.

  utils::remove.packages('r5r')
  devtools::install_github("ipeaGIT/r5r", subdir = "r-package")
