rJava error when running dismo::maxent()

[Magda Dillen]

Hello everyone. Yesterday, I was able to run the maxent function from dismo without any problems. Today, I open my computer and try to run my code again and get errors.

I first got the following error:

> dismo::maxent()
Error in .jcheck(silent = TRUE) : 
  No running JVM detected. Maybe .jinit() would help.

So I ran .jinit(). Now when I try to run the code, I get the following error.

> dismo::maxent()
Error in rJava::.jnew("meversion") : java.lang.ClassNotFoundException

My maxent.jar in saved in the dismo/java folder and rJava is installed. I am working on a windows 10 Pro (R version 3.6.1, Rstudio version 1.2.5042) What can be the problem here, since it happened over night? Is this a rJava problem?

Hi Magda,

Thanks!

Hi,

In case somebody runs on the same problem, I uninstalled and reinstalled r, rstudio and java, and afterwards the error was gone.
