| # Apache Felix |
| |
| The **Apache Felix** project is a collection of semi-related **OSGi** sub-projects that build and release individually. |
| |
| ## Felix Framework |
| |
| The flagship project is the **Apache Felix Framework** which implements the [**OSGi Core R7**](https://osgi.org/specification/osgi.core/7.0.0/) specification. The `/framework` directory contains the source and build tree for the **OSGi**-compliant |
| framework implementation. |
| |
| Directly related projects: |
| |
| - **main** `/main*` - provides an executable jar that launches the Felix framework. |
| |
| ## OSGi Core |
| |
| - [**Log Service**](https://docs.osgi.org/specification/osgi.core/8.0.0/service.log.html) `/log*` |
| - [**Resolver**](https://osgi.org/specification/osgi.core/7.0.0/service.resolver.html) `/resolver` |
| |
| ## OSGi Compendium |
| |
| Several sub-projects cover various [**OSGi Compendium**](https://osgi.org/specification/osgi.cmpn/7.0.0/) specifications such as: |
| |
| - [**Configuration Admin**](https://osgi.org/specification/osgi.cmpn/7.0.0/service.cm.html) `/configadmin` |

| - [**Event Admin**](https://osgi.org/specification/osgi.cmpn/7.0.0/service.event.html) `/eventadmin` |
| - [**Http Service**](https://osgi.org/specification/osgi.cmpn/7.0.0/service.http.html) `/http` |
| - [**Http Whiteboard**](https://osgi.org/specification/osgi.cmpn/7.0.0/service.http.whiteboard.html) `/http` |
| - [**IO**](https://osgi.org/specification/osgi.cmpn/7.0.0/service.io.html) `/io` |
| - [**Metatype**](https://osgi.org/specification/osgi.cmpn/7.0.0/service.metatype.html) `/metatype` |
| - [**Preferences**](https://osgi.org/specification/osgi.cmpn/7.0.0/service.prefs.html) `/prefs` |
| - [**UPnP**](https://osgi.org/specification/osgi.cmpn/7.0.0/service.upnp.html) `/upnp` |
| - [**User Admin**](https://osgi.org/specification/osgi.cmpn/7.0.0/service.useradmin.html) `/useradmin` |
| - [**Wire Admin**](https://osgi.org/specification/osgi.cmpn/7.0.0/service.wireadmin.html) `/wireadmin` |
| |
| ## Extra Features |
| |
| Several projects provide extra features to an OSGi runtime. |
| |
| - **bundle repository** `/bundlerepository` - Bundle repository service. |
| - **connect** `/connect` - A service registry that enables OSGi style service registry programs without using an OSGi framework. |
| - **dependency manager** `/dependencymanager` - A versatile java API, allowing to declaratively |
| register, acquire, and manage dynamic OSGi services. |
| - **fileinstall** `/fileinstall*` - A utility to automatically install bundles from a directory. |
| - **gogo** `/gogo` - A command line shell, runtime and set of base commands for interacting with and introspecting an OSGi framework. |
| - **health checks** `/healthcheck/*` - An extensible framework to monitor the status of the OSGi container at runtime. (contains **systemready**) |
| - **inventory** `/inventory` - Provides some mechanisms to get the current state of the system and therefore provides an inventory of the system. |
| - **ipojo** `/ipojo` - A *service component runtime* aiming to simplify OSGi application development. |
| - **jaas support** `/jaas` - Bundle to simplify JAAS usage within OSGi environment. |
| - **logback** `/logback` - A simple integration of the OSGi R7 Log (1.4) service to Logback backend. |
| - **OSGi metrics** `/metrics/osgi` - Collecting and publishing metrics related to OSGi applications |
| - **rootcause** `/rootcause` - Finding the root cause of problems with OSGi declarative services components. |
| - **utils** `/utils` - Utility classes for OSGi (intended for embedding within other bundles.) |
| - **webconsole** `/webconsole*` - Web Based Management Console for OSGi Frameworks. |
| - and many other **OSGi** things |
| |
| ## Build tools |
| |
| The `/tools` directory contains various build tools. |
| |
| - **maven-bundle-plugin** `/tools/maven-bundle-plugin` - A maven plugin for building **OSGi** bundles. |
| - **osgicheck-maven-plugin** `/tools/osgicheck-maven-plugin` - Maven plugin for checking several OSGi aspects of your project. |
