Hi @darenkster
Thanks for reporting this issue. You are right, this is caused by the space in the installation directory of Eclipse. This is a mistake from our side, there is a way to support this properly.
I have created a ticket, it will be part of the next sprint (starting today), so you can expect a release by the end of next week:
https://jira.sonarsource.com/browse/SLE-501
In the meantime, I suggest you move Eclipse installation dir to another folder, of you can simply revert to SonarLint 7.1
