Eclipse RDF4J: scalable RDF for Java
This is the main code repository for the Eclipse RDF4J project.
Visit the project website for news, documentation, and downloadable releases. For support questions, comments, and any ideas for improvements you'd like to discuss, please use our discussion forum. If you have found a bug or have a very specific feature/improvement request, you can also use our issue tracker to report it.
For installation and usage instructions of the RDF4J Workbench and Server applications, see RDF4J Server and Workbench.
For installation and usage instructions of the RDF4J Java libaries, see Programming with RDF4J.
mvn verify- compiles and runs all tests
mvn package- compiles, tests, and packages all modules
mvn install- compiles, tests, packages, and installs all artifacts in the local maven repository
mvn -Pquick install- compiles, packages and installs everything (skipping test execution)
These commands can be run from the project root to execute on the entire project or (if you're only interested in working with a particular module) from any module's subdirectory.
To build the full RDF4J project, including onejar and SDK files and full aggregated javadoc, from source, run:
mvn -Passembly package
The SDK and onejar will be available in
assembly/target. Individual module jars and wars will be in
target/in their respective modules.
Modern IDEs like Eclipse, IntelliJ IDEA, or Netbeans can of course also be used to build, test, and run (parts of) the project.
