My Eclipse information is copied below.
upgrade the Eclipse to Eclipse Java EE IDE for Web Developers. Version: Mars.2 Release (4.5.2) Build id: 20160218-0600
I have installed sonarlint 2.2.0 successfully. But it can only be found in installed software. It can not be enabled in project configure or project properties.
SonarLint 2.2+ requires Java 8.
Make sure that you are running Eclipse with Java 8.
