Dear archimate2rdf team,
I passed a very simple model xml file (created in just 10 min in the Archimate Tool, and i am getting this error:

C:\>java -jar archimate2rdf.jar /archimate_test_files/test_archimateOExml.xml /archimate_test_rdf/test_archimateRDF.rdf

Could not find the main class: org.bp4mc2.archimate2rdf.Convert. Program will exit.

Could I ask how to solve it?
I have the jar file just in the parent folder of the xml input and output.
I am using Archimate version 4.5.1.

How did you compile the jar? Typically you would use maven (mvn clean package) which creates the appropriate jar in the target folder. You should at least use the java version 8 jdk.

Thank you @architolk , It was the java jdk 8 PATH. The bin folder It was not in my global path environment. After download the java version 8 jdk and add the path into the %PATH% the problem is solved.

1. Download java JSDK 8 (need to register in Oracle)
2. Run in the cmd (as administrator)
   set PATH_HOME = %PATH_HOME%; "C:\Program Files (x86)\Java\jre1.8.0_51\bin"

After these 2 paths I also realized the file cannot contain spaces. Now is working perfectly. Many thanks again.
