JRebel tries to create a directory for license, properties, logs and boot cache and by default it places it under %USERPROFILE%/.jrebel
however in your case the path contains some unicode characters.
This is not properly supported so you will need to define a non-unicode path for the base folder via the VM argument -Drebel.base=[path]
or the environment variable REBEL_BASE=[path]
.
For example:
java -agentpath:C:/path/to/jrebel/lib/jrebel64.dll -Drebel.base=C:/some/path foo.Main
This folder will be created if it does not exist.
