This article outlines the class loader hierarchy employed by Son= arQube and is intended to assist plugin authors in understanding what class= es/resources are accessible to their plugins at runtime.
The SonarQube classloader:
For each plugin, a classloader is created as a child of the SonarQube cl= assloader. By default, the plugin classloader uses parent-first delegation = model.
Search order for parent-first model:
A plugin can explicitly use the child-first model (see the property useChildFirstClassLoade= r). In this case, the search order is :
Each plugin has its own class loader, so by default a plugin cannot use =
a class defined in other plugins. This constraint can be bypassed if a plug=
in explicitly exports a subset of classes. These classes must be defined in=
"org.sonar.plugins.<plugin key>.api" or any of its potential sub-packages. For this reason this feature is r=
eserved to the plugins hosted in the forge of open-source plugins.
For example the DBCleaner plugin shares the class
s.dbcleaner.api.PeriodCleaner. Any plugin can use this class.
