Planning to implement sonarqube 7.9.6 for our projects (using Java 8). Couldn’t find what version of gradle is supported by sonarqube 7.9.6 in the documentation.
There’s no specific mapping of Gradle version to SonarQube version (no known compatibility issues exist). However, please be aware that SonarQube v7.9.6 is an EOL version of SonarQube you won’t be able to find support for. You need to use at least the minimum supported version of SonarQube, v8.9.6 (maybe an upgrade is in your future).
