Implementing OptaPlanner in Eclipse

Implementing OptaPlanner in Eclipse using JAVA

[@Maaaarsel]

Thanks Vikas. For newer versions of Eclipse, when adding .jar in the Properties/Java Build Path/Libraries (min 14:30) be careful to select the Classpath, and not the Modulepath. Regards.

I am looking for an Optaplanner for Bangalore location. If you have any references please share.

Hey Vikas. I am using a newer version of eclipse. When I follow the steps plus ensuring I add it to classpath as Maaarsel stated the program loads but then when you click on the examples this error message comes up: Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: The directory dataDir (C:\Users\Hussain Zubaidi\Desktop\optaplanner_eclipseWS\CLMP Work Rota\data
urserostering) does not exist.
Either the working directory should be set to the directory that contains the data directory (which is not the data directory itself), or the system property org.optaplanner.examples.dataDir should be set properly.
The data directory is different in a git clone (optaplanner/optaplanner-examples/data) and in a release zip (examples/sources/data).
In an IDE (IntelliJ, Eclipse, NetBeans), open the "Run configuration" to change "Working directory" (or add the system property in "VM options").

can i ask you something sir? why my eclipse show an error sign? is that okay?

[@felixcheruiyot3943]

Using maven pom.xml was easier for me.

[@HammadAKhtar09]

Did you setup optaplanner using maven pom.xml. I am struggling with it. Thanks in advance
