Java versions nightmare

[matteodefelice]

Hi, yesterday I had to upgrade Java to version 8 on my ubuntu machine. Well, I'm still trying to resurrect the whole loadeR ecosystem.
I swichted back to version 7 using update-alternatives, reinstalled rJava from sources, did the javareconf from sudo but when:

> devtools::install_github(c("SantanderMetGroup/loadeR.java")

rJava' seems to work, .jinit()` doesn't trigger any error and this happens both on Rstudio and on R in the terminal. Any clue?

Apparently in 2017 you still have to reboot your system...
after installing rJava from r-forge, adding JAVA_HOME in my conf files, doing javareconf something like 100 times...after the reboot I could install your packages...

Hi Matteo,
I had exactly the same issue last week after java version upgrade (I needed v8 for other applications). I struggled for a while with no success with update-alternatives, and finally came up with the solution after reboot (for a different reason). Thanks for reporting anyway. It may help others in the same situation.

Matteo and Joaquín,
Just for the record , could you report your operating system and version?

The java update in OSX it's tricky but I would no expect this weird requirement with linux.

If a reboot it's requiered it's because a some cleanup of in memory process had happened

Hi everyone,

After a lots of trying and testing I still get this error:

devtools::install_github(c("SantanderMetGroup/loadeR.java", "SantanderMetGroup/climate4R.UDG", "SantanderMetGroup/loadeR")) Downloading GitHub repo SantanderMetGroup/loadeR.java@HEAD Error in utils::download.file(url, path, method = method, quiet = quiet, : download from 'https://api.github.com/repos/SantanderMetGroup/loadeR.java/tarball/HEAD' failed

The package climate4R.UDG have been installed well.

Really looking forward to using this package !
