How do I save Eclipse launch profiles across workspaces?

Question

When I copy an Eclipse project directory, it contains the .classpath and .project files so that when I take that same directory to another Eclipse instance, I don't have to setup my build path and such (assuming that all the resources are contained in the project, and not external.)

However, this procedure doesn't cause launch profiles to "travel" with the directory.

Is there some other file/directory structure I can "carry around" to another instance of Eclipse that will include my launch profiles?

Answer 1

The .launch xml files (launcher definition) are found in

[eclipse-workspace]\.metadata\.plugins\org.eclipse.debug.core\.launches 

Just copy them into your <project>/.settings directory.
Refresh your project, and there you have it: those launcher configuration are available, and you can copy them along the rest of your project files.

Warning: do uncheck the option "Delete configurations when associated resource is deleted" in the Run/Launching/Launch Configuration preference panel: it is common ot soft-delete a project in order to import it back again, to force a reinitialization of the eclipse metadata,... but this option, if checked, will removed your detailed launch parameters!

Jared adds:

There is no .settings directory in my project directory - I created it and put the .launch file in there, refreshed my project, and it doesn't have any Run profiles. Do you have to mirror the directory structure under .metadata?

Just create the .settings directory (it is actually created when you have project specific settings as illustrated in the question "Maintaining a common set of Eclipse preferences").
Then delete the same .launch file from the .metadata directory.
Then refresh your project and go to the "Run Configurations" Panel: you will see your launch configurations still available, except they are stored where they belong: within your project directory and not buried under an obscure workspace metadata thingy.

Update June 2012

I always seen my launch configurations, saved under PROJECT_LOC/.settings, automatically imported when reloading the Eclipse workspace.
However, as described in "Tip: Creating and Sharing Launch Configurations (2007)", you should be able to reference a launch configuration saved into any subdirectory of your project if you go to the "Common" tab of your "Run Configurations" wizard.

So saving your launcher anywhere in the project won't display them automatically in the "Run Configurations" section of the preferences.
But declaring a new one, sharing its launcher as a "Shared file" (as illustrated above), and then overwriting that launcher with the actual one you had previously saved would update that run configuration.

Answer 2

Try choosing a shared file location inside your workspace from the "Common" tab of the launch configurations (profiles).
