Install SonarLint 7.4.0.46482 in Eclipse 2018-12

Hi,

i guess your Eclipse runs on Java 8 !?
see SonarLint | Eclipse Plugins, Bundles and Products - Eclipse Marketplace | Eclipse Foundation

SonarLint requires Eclipse to use Java 11+ as runtime (but you can analyze Java projects targeting older Java versions).

This thread might be helpful
