安装R包r5r时提示需Java SE Development Kit 11的问题求助

背景与已完成操作 #

我按照r5r官方教程安装并使用该包，执行以下代码过程均正常（已提前安装64位Java）：

options(java.parameters = '-Xmx2G')
install.packages('r5r')

library(r5r)
library(sf)
library(data.table)
library(ggplot2)
library(mapview)
mapviewOptions(platform = 'leafgl')

data_path <- system.file("extdata/poa", package = "r5r")
poi <- fread(file.path(data_path, "poa_points_of_interest.csv"))
points <- fread(file.path(data_path, "poa_hexgrid.csv"))
points <- points[ c(sample(1:nrow(points), 10, replace=TRUE)), ]

报错详情 #

运行r5r_core <- setup_r5(data_path = data_path, verbose = FALSE)时触发错误：

Error in setup_r5(data_path = data_path, verbose = FALSE) : 
  This package requires the Java SE Development Kit 11.
Please update your Java installation. The jdk 11 can be downloaded from either:
  - openjdk: jdk.java.net/java-se-ri/11
  - oracle: www.oracle.com/java/technologies/javase-jdk11-downloads.html

已尝试的解决措施 #

1. 已从OpenJDK官网下载并安装JDK11，包括使用installr包的install.jdk函数完成安装
2. 自定义find.java函数查看Java环境，输出显示系统当前仍默认指向JRE 1.8：

> find.java <- function() {
     for (root in c("HLM", "HCU")) for (key in c("Software\\JavaSoft\\Java Runtime Environment", 
                                                 "Software\\JavaSoft\\Java Development Kit")) {
         hive <- try(utils::readRegistry(key, root, 2), 
                     silent = TRUE)
         if (!inherits(hive, "try-error")) 
             return(hive)
     }
     hive
}

> find.java()

$BrowserJavaVersion
[1] "11.341.2"

$CurrentVersion

$`1.8`
$`1.8`$JavaHome

$`1.8`$MicroVersion

$`1.8`$RuntimeLib

$`1.8.0_341`
$`1.8.0_341`$JavaHome
[1] "C:\\Program Files\\Java\\jre1.8.0_341"

$`1.8.0_341`$MicroVersion
[1] "0"

$`1.8.0_341`$RuntimeLib
[1] "C:\\Program Files\\Java\\jre1.8.0_341\\bin\\server\\jvm.dll"

$`1.8.0_341`$MSI
[1] "<subkey>"

3. 尝试手动设置JAVA_HOME，但路径指向的是JRE 1.8的jvm.dll文件：

Sys.setenv(JAVA_HOME='C:\\Program Files\\Java\\jre1.8.0_341\\bin\\server\\jvm.dll')

环境信息 #

• R版本：4.1.3
• 操作系统：Windows 10 x64

疑问 #

我哪里操作有误？下载的JDK11是否需要额外配置才能让R识别到？
