I usually install and uninstall different versions of Eclipse for fun. I don't want to install many plugins. I prefer to start with fresh install to test the IDE.
The problems comes when I have to config all the external tools that I always use (E.g. run jconsole).
Also I want to backup my launch configurations.
Do you know where Eclipse save this launch configurations?
These configrations are located in . metadata/. plugins/org. eclipse.
Run > External Tools > External Tools.... Select the Program configuration. Click the New button. Enter a name for your external tool (for example, My External Tool). Click the Browse File System button.
External tools are applications or scripts that typically act as extensions to your development environment. For example, they may be used to execute scripts to package and deploy your application or to run an external compiler on your source files.
As I said in this question "Which eclipse files belong under Version Control", the .launch xml files (launcher definition) are found in
[eclipse-workspace]\.metadata\.plugins\org.eclipse.debug.core\.launches
You can actually move them into your project directory:
when your project is refreshed, those configurations will be displayed in the "Run configuration" dialog.
That way, those launch parameter files can be also managed into a VCS within your other project files, instead being buried within the workspace metadata area.
Warning: do uncheck the option "Delete configurations when associated resource is deleted" in the Run/Launching/Launch Configuration preference panel: it is common to 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!)
