How to remove launch configuration histories in eclipse?
This question seems to be well answered here
, however, to make changes I have simply deleted every undesirable launch configuration from the below path.
${WORKSPACE}/.metadata/.plugins/org.eclipse.debug.core/.launches/Delete all the .class LAUNCH Files
After deleting the files, it is necessary to restart Eclipse for the changes to take effect.
Under Window...Preferences...Run/Debug...Launching...Launch Configurations, you can activate and deactivate some filters that restrict what is shown in Run...Run Configurations. I think it is what you are looking for.
