Apache Stanbol is a modular set of components and HTTP services for semantic content management.
To build Stanbol you need a JDK 1.6 and Maven 2.2.1 installed. You probably need
$ export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256M"
The following builds the Apache Stanbol plus available Enhancement Engines and a default set of linked open data for the EntityHub. If you want to have a ready to use version of Apache Stanbol, this is the way to go.
In the Apache Stanbol source directory type
$ mvn install
If you want to skip the tests, use :
$ mvn install -Dmaven.test.skip=true
The recommended lanchers are packaged under the launchers/ folder. For
instance:
$ java -Xmx1g -jar launchers/full/target/org.apache.stanbol.launchers.full-0.10.0-incubating-SNAPSHOT.jar
Your instance is then available on http://localhost:8080. You can change the
default port number by passing a -p 9090 options to the commandline launcher.
Upon first startup, a folder named sling/ is created in the current folder.
This folder will hold the files for any database used by Stanbol, deployment
configuration and logs.
If Stanbol is launched with a FactStore a folder named factstore is created
in the current folder. This folder holds the FactStore database (Apache Derby).
Eclipse is the most popular IDE among Stanbol developers. Here are instructions to get you started with this IDE. For other IDEs / editors, please refer to their documentation and maven integration plugins.
To generate the Eclipse project definition files, go to Stanbol source directory and type:
$ mvn eclipse:eclipse
If you want to recreate already existing Eclipse projects, you have to delete
the old ones first by using eclipse:clean.
Then in Eclipse, right click on the Project Explorer panel and select
your source folder from the following menu / import wizard:
> Import... > General > Import Existing Projects into Workspace
You will also need to setup the build path variable M2_REPO pointing to
~/.m2/repository (where ~ stands for the path to your home folder). To set
up this variable go to:
> Window > Preferences > Java > Build Path > Classpath Variables > New...
If you plan to contribute patches to the project, please ensure that your style
follow the official sun java guidelines with 4 space indents (no tabs). To
ensure that your files follow the guidelines you can import the formatter
definitions avaiable in the conventions/ folder:
> Window > Preferences > Java > Code Style > Formatter > Import...
You can then apply the formatter to a selected area of a Java source code files
by pressing Shift+Ctrl+F.
To debug a locally running Stanbol instance from eclipse, run the stanbol launcher with::
$ java -Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n \
-jar org.apache.stanbol.some.launcher-[VERSION].jar -p 8080
In eclipse, you can then create a new "Debug Configuration" with type "Remote Java Application" and connect it to localhost on port 8787.
To check for license headers within the source code Stanbol uses the RAT Maven plugin [1]. You can activate a 'rat:check' by using the 'rat' Maven profile.
For example to check the licenses in the Stanbol Framework use
$ mvn install -Prat
You should read [1,2] before doing any release related actions.
To do a release test build, you have to activate the 'apache-release' profile. For building Apache Stanbol plus signing the artifacts as it would be done during a release you can use
$ mvn install -Papache-release
The 'apache-release' profile will be automatically activated when the Maven release plugin [3] is used. For doing official release you start with
$ mvn release:prepare
