Cannot find JRI native library!

Please make sure that the JRI native library is in a directory listed in java.library.path.

java.lang.UnsatisfiedLinkError: C:\Users\----\R\win-library\3.5\rJava\jri\x64\jri.dll: Can‘t find dependent libraries

Q: I get the following error, what‘s wrong?
java.lang.UnsatisfiedLinkError: no jri in java.library.path

Usually it means that you didn‘t setup the necessary environment variables properly or the JRI library is not where it is expected to be. The recommended way to start JRI programs is to use the run script which is generated along with the library. It sets everything up and is tested to work. If you want to write your own script or launcher, you must observe at least the following points:

R_HOME must be set correctly
(Windows): The directory containing R.dll must be in your PATH
(Mac): Well, it‘s a Mac, so it just works ;).
(unix): R must be compiled using --enable-R-shlib and the directory containing libR.so must be in LD_LIBRARY_PATH. Also libjvm.so and other dependent Java libraries must be on LD_LIBRARY_PATH.
JRI library must be in the current directory or any directory listed in java.library.path. Alternatively you can specify its path with
-Djava.library.path= when starting the JVM. When you use the latter, make sure you check java.library.path property first such that you won‘t break your Java.
Depending on your system, the R verison and other features you want to use, you may have to set additional settings such as R_SHARE_DIR, R_INCLUDE_DIR and R_DOC_DIR.

1、在环境变量中设置R_HOME；

2、在系统path中加入路径，指向包含R.dll的目录，如果你的系统为64位系统，可能是在x64目录中
3、工程中配置java.library.path为jri.dll所在的路径

设置完成以后记得重新启动eclipse
