Eclipse存储首选项在哪里？

Question

When I change a setting in a window like in the screenshot below, where are those settings actually stored?

Bonus: Is there any way, using Java, Eclipse RCP etc, to access the settings programmatically?

Thanks!

Answer 1

Source : Eclipse wiki

If you want to keep preferences from one version to the other, export them using File/Export/Preferences.

Preferences are stored in various places (this applies to Eclipse 3.1)

for each installation (but this may vary for multi-user installations), in files stored in: <eclipse_home>/eclipse/configuration/.settings/

There is typically one file per plugin, with a prefs extension. Note that very few plug-ins use installation-wide preferences.

for each workspace, in files stored in <workspace>/.metadata/.plugins/org.eclipse.core.runtime/.settings .

There is typically one file per plugin, with a prefs extension. for each project --for project-level settings -- in files stored in a .settings sub-directory of your project folder.

Here's the article to access preferences using java code.

Answer 2

The preferences are stored in prefs files in the workspace at .metadata/.plugins/org.eclipse.core.runtime/.settings . There is one prefs-file for each plugin contributing preferences.

The programmatical access to the entire preferences is done with IPreferencesService the which you may obtain using Platform.getPreferencesService() .

You may find more information and examples on how to use them in the Runtime preferences Eclipse help page.

Answer 3

Search for it:

Change some setting in Eclipse then run:

find ~  -type f -mmin -5 | grep "\.settings"

This will discover files modified in last 5 minutes.

Mine was in workspace , literally...

~/workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.ui.workbench.prefs

Answer 4

You can see most of the relevant eclipse settings (mainly for JDT) in the saneclipse project from Lars Vogel .

See the vogellacompany/com.vogella.saneclipse repo, which will tweak and fine-tune the settings of:

com.vogella.saneclipse.preferences/.settings/org.eclipse.jdt.core.prefs
com.vogella.saneclipse.preferences/.settings/org.eclipse.core.runtime.prefs
com.vogella.saneclipse.preferences/.settings/org.eclipse.core.resources.prefs
com.vogella.saneclipse.templates/.settings/org.eclipse.jdt.core.prefs
com.vogella.saneclipse.fileextensions/.settings/org.eclipse.jdt.core.prefs
com.vogella.saneclipse.fileextensions/.settings/org.eclipse.pde.core.prefs
