Arduino for STM32

I think issue is relared to '(' and ')' i the path.you should try to protect it with one or two '\'.

I ran into the same problem. Has there been a solution found in the meantime ?

You should check if issue has been reported:

Some issue has already been closed:

Sorry, late answer.

If it can help you, the manual workaround is in that way: add < and > around the concerned value. The action has to be done in Eclipse, under the project properties.
