The build file is missing because the list of modules is not built until the Liberty Explorer window is opened. We need to move the logic to build the list of modules out of the LibertyExplorer class and into an independent place like LibertyModules so it can be used when needed. |

Steps to Reproduce:
The dev mode doesnt get started and we will encounter the exception.
However, once we start using the default Start action without any configuration, stop it, and then try starting again with the configuration, it works.
Verified the same issue occurs with 24.0.9 version also.
