System Requirements

• Java Development Kit (JDK) version 1.8 or higher.
• Eclipse version 4.4 or higher. We recommend the Eclipse IDE for Java Developers distribution.

Different version of DKPro Core have different version requirements.

For Windows Users

Note: On your machine the Java path may be different, e.g. because you are using a localized Windows version it may be C:\Programme\... -or- because you may have a Java version other than 1.8.0.51.

• Edit your eclipse.ini and add/change the following lines (the -vmargs line should be present already):

-vm
C:/Program Files/Java/jdk1.8.0_51/bin/javaw.exe
-vmargs

• Make sure that the linebreaks are as shown above (the formatting is actually necessary)
• Open Eclipse
  • Open the preferences
  • Go to Java -> Installed JREs
  • Click Search and choose your Java directory
  • Close the preferences and re-open them
  • Select jdk1.8.0_51 as your JRE (this should match the entry you added in the eclipse.ini)
