What is JaCoCo agent?
JaCoCo uses class file instrumentation to record execution coverage data. Class files are instrumented on-the-fly using a so called Java agent. This mechanism allows in-memory pre-processing of all class files during class loading independent of the application framework.
What is JaCoCo library?
JaCoCo is a free code coverage library for Java, which has been created by the EclEmma team based on the lessons learned from using and integration existing libraries for many years.
Does JaCoCo work with Java 11?

Does SonarQube need JaCoCo?
What are branches in JaCoCo?
Branches (C1 Coverage) JaCoCo also calculates branch coverage for all if and switch statements. This metric counts the total number of such branches in a method and determines the number of executed or missed branches. Branch coverage is always available, even in absence of debug information in the class files.

You can configure SonarQube authentication and authorization to an LDAP server (including LDAP Service of Active Directory) by configuring the correct values in $SONARQUBE-HOME/conf/sonar. properties. The main features are: Password checking against the external authentication engine.
What is complexity in JaCoCo?
JaCoCo also calculates cyclomatic complexity for each non-abstract method and summarizes complexity for classes, packages and groups. According to its definition by McCabe1996 cyclomatic complexity is the minimum number of paths that can, in (linear) combination, generate all possible paths through a method.
