When I run my Eclipse RCP application, it creates a whole lot of directories

  • 0

When I run my Eclipse RCP application, it creates a whole lot of directories in my $HOME/.eclipse directory. What is this?

I don’t want the files there, how can I hinder them from getting there? The rational for this: the application must run very clean and only leave files at one specific location (not $HOME/.eclipse).

I’d figured it was controlled by osgi.instance.area so tried to set this to different values (a directory, @none, @noDfault etc…) but can’t stop the application from creating directories in $HOME/.eclipse. -data and other arguments works as expected.

    On my system the only thing that is stored in .eclipse is the Equinox Secure Storage. Here is the blurb on the doc page for that:

    By default, secure storage is located in your home directory. On Windows that typically resolves to “C:\Documents and Settings\.eclipse\org.eclipse.equinox.security”. This location is selected to allow multiple Eclipse-based applications to share the same secure storage.

    If you would like to modify the location of the default secure storage, you can use the “-eclipse.keyring ” runtime option. The is a path to the file which is used to persist the secure storage data.

    Here is the online reference.
