Use Java 8 (it may work with newer versions, see below)
Get the iObserve variant of the JPetStore from JPetStore-6 <https://github.com/research-iobserve/jpetstore-6>
Use git clone https://github.com/research-iobserve/jpetstore-6.git
to obtain the JPetStore
Download Jetty <https://www.eclipse.org/jetty/download.html>. Use a version which is compatible with your Java version. Kieker 1.14 with AspectJ will not work with Java 11. This will change in the 1.15 which supports Java 11.
