As a head's up, the page with the Hello World on the tutorial https://pivot.apache.org/tutorials/hello-world.html contains the following command to compile the Hello World application:
java -cp pivot-core-*[version]*.jar;pivot-wtk-*[version]*.jar; pivot-wtk-terra-*[version]*.jar;pivot-tutorials-*[version]*.jar org.apache.pivot.wtk.DesktopApplicationContext org.apache.pivot.tutorials.HelloJava However, the latest release of the .jars (apache-pivot-2.0.3.zip) does not contain pivot-tutorials-*2.03*.jar (nor any version).
