Upgraded from SonarLint 5.3.0 and now there is no sign of SonarLint in Eclipse. There is no Preferences > SonarLint, no SonarLint views, nothing. How can I get this working?
Maybe you are you running Eclipse with a JVM version lower than 11? SonarLint requires a minimal Java runtime of Java 11.
You can check the current JVM version in Eclipse Help → About → Installation Details → Configuration:
Yes, that is the issue. I run two Eclipse environments, one using Java 8 for supporting a legacy product which requires Java 8 and another using Java 11. I hadn’t checked the Java 11 environment with the 7.3.1 SonarLint yet.
