In my Eclipse preferences, I have "Refresh using native hooks or polling" selected.
If I make a change to a Java file outside of Eclipse, the project that contains that Java file automatically refreshes and rebuilds that file as it should. However, if I make a change to a file under src/main/resources/... from an external editor, it is not automatically refreshed. I have to select the project and press F5 to get it to refresh.
Is there a way to configure Eclipse to automatically refresh any resources under src/main/resources?
In Eclipse
Run > External Tools > External Tools Configuration
Create a new Program configuration Point the location to an exe that is very fast
On the Refresh tab, choose Refresh Resources upon completion, The Entire Workspace
On the Build tab, deselect Build before launch
Can I refresh the explorer without pressing F5 button? I want it keep refresh by itself while running the project.
I'm using Eclipse Mars 4.5.1
From eclipse doc Workspace
Select Check Box: Refresh using native hooks or polling
It is needed to check both "Refresh using native hooks or polling" and "Refresh On Access".
But not only check the "Refresh On Access".
there's a new preference Settings > General > Workspace > Refresh On Access (aka Lightweight Refresh). This preference causes Eclipse to automatically refresh resources when it discovers that they're 'out-of-sync'. When opening, reading or searching files, it'll prevent out-of-sync errors from occurring.
Other option is preference Settings > General > Workspace >Refresh using native hooks or polling
If this option is turned on then the workspace resources will be synchronized with their corresponding resources in the file system automatically using native refresh providers (on Windows) or a polling mechanism.
Note: This can potentially be a lengthy operation depending on the number of resources you have in your workspace.

Can Eclipse refresh resources automatically?
I write a *bat-script to update my workspace projects to HEAD revision.
The problem is that I stil have to need refresh the workspace in project explorer of eclipse manually.
(Otherwise, new files want shown)
Can I use "External Configuration" or something like that to run my bat and after finished that eclipse refreshes the workspace?
You can use 'Run > External Tools > External Tools Configurations' to configure and run a Program.
This configuration has a 'Refresh' tab where you can configure the refresh action to take when the program finishes.
Is there a possibility to refresh the files and folders of a project within eclipse at the end of a maven build automatically.
Usually I'm building from commandline. After a build e. g. the target folder should be refreshed.
Additional info: the maven build runs in the command line and eclipse should update automatically when it ended.
Use Run as -> Maven build... In the run configuration/build properties go to the refresh tab and select the refresh option you want.
Note that the eclipse build and the maven build may interfere, so make sure that you turn off the Build automatically option in the Project menu before staring the maven build. You may get indeterministic compilation errors otherwise.
Here is an eclipse plugin that implements the external hook for refreshing: https://github.com/andrask/maven-eclipse-control-plugin
I dont think so, there is no option to link the two things.
But eclipse has an option Refresh on access which might be useful for you.
For me, the accepted answer of using Run as -> Maven build... and the Refresh option did not refresh the target folder in Eclipse. I needed to do the following:
Preferences -> General -> Workspace -> Refresh using native hooks or polling
When enabled, any changes made by external editors will be automatically discovered by the Workbench. On some systems there may be a slight delay if polling is used.
Eclipse (3.4.2 with PyDev) deals with out-of-sync resources (files that have been edited outside of the IDE) differently from other IDEs that I've used, where only resources with editors open are considered out-of-sync. In Eclipse, any resource can go out of sync.
This means that when I perform a search after any file has changed outside of Eclipse, I get an error dialog telling me that files are out of sync, even if they have no open editors. As far as I can tell, there is no global refresh command, so I'm forced to read the project names (I have several projects) in the error dialog, and do a right-click + refresh for each of them.
I've checked the Refresh Automatically setting in Settings > General > Workspace, but this has no effect. Is there any way to get Eclipse to always just load non-active resources from disk?
This issue will be fixed in Eclipse 3.7 (Indigo). While "Refresh Automatically" does eventually bring resources back into sync, the refresh hook only exists for Windows, so on Linux and Mac OS it has to poll the filesystem periodically.
From 3.7 there's a new preference Settings > General > Workspace > Refresh On Access (aka Lightweight Refresh). This preference causes Eclipse to automatically refresh resources when it discovers that they're 'out-of-sync'. When opening, reading or searching files, it'll prevent out-of-sync errors from occurring.

I think if you click on the project node in the Project Explorer and press F5 or right click and select Refresh, all resources for that project will be refreshed. Also, if you CTRL+click on multiple projects, you should be able to refresh multiple projects at the same time.
A single click on a project, a CTRL+A to select everything, and an F5 should do exactly what you need - refresh everything.
I'll have to test this when I get the chance, but I believe this is how I overcame similar problems in the past.
I've noticed that this answer routinely is getting down voted. I'd like to point out that the question refers to a specific version of Eclipse: 3.4.2. There was actually no automatic method to refresh out-of-sync resources until version 3.7 Indigo of Eclipse, as mentioned in James Blackburn's answer. The method described in this answer is the only method to achieve this in version 3.4.2 (and any other version before 3.7 Indigo).
Out of synchronization problem is common in eclipse IDE so you have to check this option windows -> preference -> Workspace -> refresh using native hooks or polling.
Eclipse Helios possesses a built in refresh feature at Preferences > General > Workspace. It's in the same spot where you disable automatic builds. Select refresh automatically. A plugin with the same functionality is Andrei Loskutov's Filesync Plugin. The update site address is: http://andrei.gmxhome.de/eclipse/. During installation, select Eclipse 3.5-3.7 plugins > FileSync.
Given that Java 7 has an api for filesystem hooks, one would think that refresh could be handled better in Eclipse.
Edit: Actually, there is a plugin that uses this mechanism: https://github.com/psxpaul/EclipseJava7Refresher
There is a global refresh - have nothing (or everything) selected in the package explorer and press F5 (or right-click on empty space and select Refresh). Of course, this could take rather long if you have large projects.
The global refresh actually exists in plain Eclipse without any plugins and without selecting every project in your workspace.
Basically you need to deselect everything in your project explorer and hit F5. To do that Ctrl+click the selected resource in the project explorer and hit F5.
A global refresh is really missing in Eclipse. The above procedure with selecting all projects and then running refresh (e.g. F5) does not work if you have closed projects included in your selection. This means, if you have 1/2 of your many projects closed as I do, you find yourself manually Ctrl-clicking through your dozens of projects. This is quite painful. I wish Eclipse would simply ignore closed projects.
Perhaps you should add a feature request on the eclipse site:
https://bugs.eclipse.org/bugs/
I think it would be a great idea to add a preference for automatically refreshing out of date resources.
Yes, Refresh on Access is long overdue ... those answers to this and similar enquires usually suggested enabling the global auto-refresh, which could take an age for large remote projects.
In fact there are those who would say that Refresh on Access should have been the original (< 3.x) default behaviour ...
I managed to solve this by creating a new "external tool" run config that executes a blank batch file. In the run config, you can have it refresh the workspace when complete. Then I created a macro using Practically Macro that 1) executes the last external tool run config (refreshing the workspace), then 2) executes the last debug run config (running my app). If you uncheck "Allocate console" then the completed external tool entry won't show up in the debug window.
Even if the solutions proposed by others perso are indeed correct, you have a "Refresh All" plugin for Eclipse. Simply add the Update page to your Eclipse list of update sites to install it in your IDE.
For Starting up there is an option to automatically refresh files in
Window -> Preferences -> General -> Startup and Shutdown -> Refresh workspace on startup
Click it in order to have a "fresh" start in eclipse. :)
