Setting up Eclipse

The full setup requires:

• Eclipse
• JDK 7+
• Maven 3

Additionnaly, Eclipse requires:

• Scala support
• Git support

Note: Maven support within Eclipse is discouraged (read below)

• In Eclipse: “File” >> “New” >> “Project” >> Git >> “Clone Existing Git Repository”
• GitHub Repository read-only URL: https://github.com/dbpedia/extraction-framework/

On Maven support within Eclipse: There is a Maven integration plugin for Eclipse (M2E), but its use is discouraged: there are [conflicts between M2E and canonical Maven] (https://bugs.eclipse.org/bugs/show_bug.cgi?id=374332#c14) that seem unlikely to be fixed, even though there is a workaround for it. In any case, it is possible to generate the Eclipse configuration files with vanilla Maven ("mvn eclipse:eclipse"). If your Eclipse installation has Maven support, you may disable the Maven nature of the project.

You can use either:

• a minimal Eclipse + Scala IDE installation (read below).
• your current Eclipse (which most likely already includes M2E) + [the Scala IDE] (http://scala-ide.org/download/current.html),
• [the Eclipse + Scala IDE bundle] (http://scala-ide.org/download/sdk.html) (which includes M2E),

Minimal Eclipse installation

Go to http://download.eclipse.org/eclipse/downloads/ Select the Eclipse version you want to use.

Download only the following:

*Platform Runtime Binary (a minimal Eclipse distribution)

*JDT Runtime Binary (to support Java -and thus, Scala- as a developing language)

1. Extract the Platform Runtime Library (this will generate an "eclipse" folder)

2. Start Eclipse from "eclipse/eclipse"

3. Install the JDT Runtime Binary from within Eclipse:

Start Eclipse >> Help >> Install >> add New Update Site >> Archive... >> (select the ZIP file).

Deactivate “Contact all update sites”!!! Otherwise installation takes forever. Deactivate “group items”, otherwise Eclipse won’t list any items in the archive.

4. Install [the Scala IDE] (http://scala-ide.org/download/current.html)
