Batch allows bootstrappers like maven and ant to inject their own objects to picocontainer, so that they are available at runtime by plugins.
- introspect maven dependencies from a sensor
- execute an ant task from a sensor
The maven extensions are being fully dropped and ant objects are not used for a while. They were used a long time ago when the ant task tried to introspect ant file without calling sonar-runner. Moreover the recent Gradle plugin does not use these extensions.
These bootstrapper extensions are not used anymore and can be dropped.
