NoClassDefFoundError when opening Experiments Model Editor

Description

I followed this documentation to install and use Experiment Automation, but when creating an .experiments file or opening an existing one the follow error is thrown [1]. This makes the editor unusable.

org.eclipse.core.runtime.CoreException: Plug-in "org.palladiosimulator.experimentautomation.editor" was unable to instantiate class "org.palladiosimulator.experimentautomation.experiments.presentation.ExperimentsEditor".

I could not reproduce the particular problem of opening or creating new Experiments models with the generated Experiments Model Editor. I used the current nightly update site (as of 2020-07-14) and Eclipse Modeling Tools 2020-06. I tried both opening an existing .experiments-File in the provided example project (org.palladiosimulator.experimentautomation.examples.espresso) as well as creating a new file with the generated wizard.

I suggest to close this issue and reopen it (and get back to me) when this problem occurs again.
