How to remove launch configuration histories in eclipse?

Question

Right click an arbitrary existing project in Package Explore, choose "export..." - "Java" - "Runnable JAR file", I find all the old projects in the "launch configuration" list. Those projects have already been removed from the disk, and are not visible in the Package Explore. How can I remove them from that list? I'm using eclipse indigo.

There is also option Delete configurations when associated resource is deleted on the Preferences>Run/Debug>Launching>Launch Configurations page. It is better to turn it on to prevent further creation of "orphaned configurations". – Amigo

Answer 1

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.

Since those projects have already been removed from the disk, there's nothing about them in the "run configurations". I only found the old projects' history when exporting Runnable JAR file. – Kochi

Sorry, missed the point but in the preferences, you have a Lauch Configuration settings under run/debug and there you can activate some filters. I think it is what you are looking for. If so i'll edit my answer. – Kazim

Thanks a lot! I've found and deleted the old configurations after unchecking the items "Filter configurations in closed projects" and "Filter configurations in deleted or missing projects". – Kochi

I added a filter but still have the launch configuration of a project that does no more appear in the projects list. Interestingly, the annoying old entry does not appear under "Run Configurations…", so it is not possible to delete the old one over the GUI. Is there a way to remove it in the configuration files? – Monolithic

Answer 2

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.

Theres another place: ${WORKSPACe}\.metadata\.plugins\org.eclipse.debug.ui with the file launchConfigurationHistory.xml. Edit this file and remove those entries you don't want. – Edrei

This is the only solution that removed my "Launch configuration" history from the Runnable JAR File Export window ( right click on project > Export... > Runnable JAR file > Next ). But it was applied only after I restarted Eclipse. – Valery

After deleting eclipse have to be restarted. – Weariful

I deleted everything except for my webserver launch configurations. Restart. Then simply run or debug any project you need and the configuration will be re-generated. – Cherey

Answer 3

Eclipse menu -> Run -> Run Configurations... pops up the list of all viable run configurations, grouped by type. You are looking for those under Java Application. Any of these are deletable. Delete them and they will no longer show up in Run/Launch configuration lists.

if the preferences are not set correctly, the configurations of deleted projects will not shown here. Thanks all the same! – Kochi

Answer 4

• Go to Run->Run configuration. Delete the existing saved projects under the Java Application.
• Run the class, having main method from eclipse. It will be automatically set.
• create runnable Jar.

Go to Run->Run configuration. Delete the existing saved projects under the Java Application.

Then run the class, having main method from eclipse. It will be automatically set.

Now create runnable Jar.
