== Build KOMMA with Maven

KOMMA is a plain Maven project. You can simply use `mvn package` to compile and package all modules or `mvn install` to install them within your local Maven repository.

If you like to build an Eclipse update site (or rather a P2 repository) for KOMMA then use

[source,text]

----

mvn package -Pupdatesite

----

to create it. Afterwards a P2 repository can be found at `features/net.enilink.komma.updatesite/target/repository`.

== Build KOMMA IDE

KOMMA IDE is an Eclipse-based development environment with editing components for RDF, RDFS and OWL.

You can either use the update site as described above to install the modules in Eclipse or build the whole IDE package using:

[source,text]

----

mvn package -Pupdatesite && mvn package -Prelease -f ide/pom.xm

----

Afterwards Linux and Windows packages can be found at `ide/target/products`.

== Develop KOMMA with an IDE

- *Eclipse:* You can import the KOMMA projects into your workspace by executing

__File > Import > Maven > Existing Maven Projects__.

- *IntelliJ IDEA:* You can import the KOMMA projects by executing

__File > New > Project from Existing Sources...__.
