Unable to get SonarLint work

RememberMe · July 20, 2021, 1:31am

I run new Eclipse EE version (2021-06) and use my old workspace (was created on eclipse 2019) Then I installed coupled plugins, but I was unable to get Sonarlint work.
So to see if the problem was caused by another plugin, I removed every old settings from my PC and download new Pure Eclipse EE (2021-06) with new workspace then Installed SonarLint and create a new simple project (i.e hello world app) to test if SonarLint is working but with no luck.
Hope anyone can help me.

I have:
OS: Win 10 x64 Pro v2004
Free Space over 200 GB
RAM 16 GB
Eclipse 2021-06

Hello, welcome to the community! And thanks for reporting this issue.

I see in your logs that class EmptyMethodCheck (responsible for rule php:S1186) is trying to initialize a regular expression with pattern \w{٣}, which is not a legal regexp pattern in Java. According to the source code for the PHP analyzer, I believe this is a locale-related issue: most probably, earlier versions of the JDK used the “English” locale to format the %d pattern, whereas the one you use now is defaulting to a locale that uses “Eastern Arabic” numbers.

This looks to me like a bug in the PHP analyzer, I managed to reproduce it by setting the JVM’s default locale to ar-EG.

I believe that as a temporary workaround, you can put the following in your eclipse.ini file, after the line that contains -vmargs:

-Duser.country=US
-Duser.language=en
