Blynk server on Raspberry Pi problem with start

Hy guys. Sorry for my bad english. I have problem with running server on Raspberry
I use this command for starting server:
pi@raspberrypi:~ $ java -jar server-0.41.12-java8.jar - dataFolder home/pi/Blynk
and error is here.
Exception in thread “main” java.lang.RuntimeException: Error unpacking static files.
at cc.blynk.utils.JarUtil.unpackStaticFiles(
at cc.blynk.server.launcher.ServerLauncher.main(
Caused by: java.nio.file.AccessDeniedException: /home/pi/static/report-email.html

… 3 more

i need help very quickly!

Also i have java 11.0.3 but server is on java 8 I think because I don’ make server I just configure server. I try deinstalled java and instal now (8.0) but then write again 11.0.3. (comand java -version)

Sounds like either a missing file, or a permissions issue.
Mine looks like this when viewed in WinSCP…

Also, I wouldn’t normally have a space betetween the “-” and the word “dataFolder”


All what you need is start server as a ROOT. In terminal write sudo pcmanfm . Then open folder in terminal and run server!
