Can I use the same Eclipse workspace simultaneously on two computers? - eclipse

My friend and I need to use the same Eclipse workspace. I've put it on an AFP server, so we can both mount the volume and use the workspace there. But will that work without problems as long as we are not editing the same file at once? For example, if there are classes Starter and View, could I be editing Starter.java and saving the project while he edits and saves View.java?
I know that Eclipse cannot normally use workspaces on AFP due to a bug. I had to add "-Dosgi.locking=java.io" to the eclipse.ini file to make it work.

Yes. But you will need to change its configurations to not lock the workspace. This is the default behaviour.
This is the option:
-Dosgi.locking="none"
Use it in your vmargs or in ini file. I do not need to mention you and your friend need some discipline to not be caught by side effects of this solution.
For example, if both are working in file A, when the first save eclipse will ask if you wish update with system file changes. If you click yes your changes will be lost.

Chrome Developer Tools add a SINGLE file to workspace not folder

I'm doing some clean up work in the stylesheets. But there are some files that I don't want to touch by accident. So I don't want them to be editable. How can I add some files to the workspace but leave the rest of the files in the folder are not added.
Basically I want to achieve below;
DevTools technical writer here. It's not possible to choose which files are editable in Workspaces. The intended use of the feature is to persist any changes in a given directory to disk.
Maybe you'd prefer to use Local Overrides?
Also, a potential workaround could be to use chmod to disable write access on the files you don't want to touch...

Multiple sub-workspaces in Eclipse

I write code in several languages (Python, C, C++, and Java) using Eclipse. Is it possible to designate a directory on my machine (say /home/workspace/) as the "primary" workspace for any Eclipse session, but then to have subfolders, /home/workspace/python, /home/workspace/java, etc., in which I can create new Eclipse projects.
I don't want to have to navigate menus and select different workspaces for each session of Eclipse that I start up. I would rather just always have permission to manipulate any projects from a variety of folders at any time, but I can't find a clear answer about whether this can be done and how to do it.
As I understand your question; You want to have one workspace, but be able to code in several different languages without switching workspace but at the same time keep the projects separated?
First I would suggest you consider several workspaces, I find it convenient to keep settings and projects in separate workspaces. I rarely have to switch language that often.
But. I think what you want to do is to keep several working sets. You create one java working set, one C++ set and associate your different projects with a working set. Then you can minimize the java working set when you are running C++. For working sets you dont need any subfolders on the harddrive.
You might also want to look into Mylyn. Its a great tool for those who often are switching context. It saves the context (eclipse perspective, open files, etc) as associated with a task.
How about setting Eclipse to prompt for the workspace at launch? It wouldn't allow you to work in two languages at once, but should do the trick otherwise.
An Eclipse workspace can contain projects slated for different languages and those projects can live anywhere on your hard drive. There are at least two ways to do what you want. When creating a new project, uncheck the Use default location checkbox and browse to or specify the folder where you want your project to live. If a project already exists import the project into the workspace using the File->Import menu option and then select Existing Projects into workspace. In the next screen make sure the checkbox for Copy projects into workspace is not selected. This will leave the source files in the original folder.
In the Project explorer view, all the projects are going to look like they live at the root level. However you can group related projects into working sets. Then select just the working set you're interested in and all the others will disappear from view.
A warning is in order if you make use of eclipse variables in external tools (and possibly elsewhere). The syntax you use for paths needs to be adjusted. For example with projects outside the workspace this syntax ${workspace_loc:/MyProject/MyFile.txt} is no longer the same as this syntax ${workspace_loc}/MyProject/MyFile.txt

How to search all open files in Eclipse?

Simple question: how do I search all the files currently open in Eclipse? Note: I don't wanna search all the files I have in that workspace, just the ones open in tabs. Is there an easy way to do this?
Closest way is selecting several resources in Navigator or Package Explorer view, then press Ctrl+H and choose 'Selected Resources' radio button. It will limit search only to selected files.
CTRL+E on Windows or Linux, and Command+E on OSX.
There's no way to do that at the moment.
The easiest solution would be to select your files manually (holding CTRL + click on file) and to specify "selected resources" as your search scope.
This may come too late for the original poster, but just in case somebody else needs to find out an answer, I had the same problem and found my solution by installing a plug-in named Instasearch. You can get it by going to Help/Eclipse Marketplace and searching for Instasearch.
You can find more about this plug-in in the following address.
http://marketplace.eclipse.org/content/instasearch
Spring produces a stand-alone Eclipse plugin (no dependencies on Spring) called Quick Search
http://marketplace.eclipse.org/content/quick-search-eclipse
For efficiency, it searches your open files first. So while it isn't purely restricting to opened files as you requested, you can still get a similar effect in practice by just clicking the first results that come up.
The currently opened files simply aren't considered special in eclipse - you have far more advanced methods of organizing your files: projects and working sets.
Working sets allow you to define sets of files, which can be used as constraints for many operations. You have to define them explicitly, but then they don't change just because you've closed a file.
There is no find-in-open-files command in Eclipse, no.
I think that the main reason find-in-open-files is not implemented in Eclipse is probably because the set of open files is for many users rather insignificant. (In fact, I don't know (or care) which files I have open. (I even have Eclipse set to automatically close editors/files when they become too many). If I want to navigate to a file, I open it. Limiting a search to the files I currently have open would be completely pointless for me.)

Opening a temporary buffer / scratchpad in Netbeans?

I often have to open a secondary editor outside of Netbeans in order to work on temporary bits of text outside of my project files. Is there a way to create temporary files in Netbeans without adding them to a project?
File -> New expects every file to be part of a project.
I know this has already been answered successfully, but there is now a proper Netbeans plugin for this requirement: http://code.google.com/p/netbeans-scratchpad-plugin/ It works nicely for me and allows multiple scratchpads which can be handy.
Also note that the Copy/Paste History plugin which is available by default (with NB7 at least) is handy for this too.
HTH,
JD
By default, there is no such feature yet (I'm using 6.5).
You could include a folder in the Favorites window, and right click > New > Empty File from the folder, it won't be part of the project.

Eclipse syntax highlighting preferences save and restore

I spend some time customizing the colors for syntax highlighting in Eclipse (Java, JSP, HTML, CSS, etc.) but whenever I try to export these settings via File|Export|General|Preferences and reimport them, the settings never completely get imported back. Some colors are restored and others are left unchanged, leaving me in an 'in between' state - very frustrating.
I'm using Eclipse 3.4 Ganymede, by the way.
Has anyone found a reliable way to save and restore Eclipse syntax highlighting settings?
I finally figured out how to do this.
I just wanted to mention beforehand that I did try to start with a fresh Eclipse install, export the preferences to a .epf file, change just one single setting, export again, and compare the files. To my surprise, trying to import settings from a minimal .epf file did not work reliably either.
The solution that worked for me was to copy these files: {Eclipse workspace directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings/*.prefs
I tried a fresh Eclipse install on another machine and after copying those files over, all my settings were restored perfectly.
The solution was to copy SOME - not all - of the files from {workspace}/.metadata/.plugins/org.eclipse.core.runtime/.settings/*.prefs into my other workspace.
In particular (per the https://stackoverflow.com/questions/96981/color-themes-for-eclipse thread):
org.eclipse.jdt.ui.prefs = Syntax Coloring
org.eclipse.ui.editors.prefs = Text Editors
Copying other files caused things to break.
There are a couple of notes to add:
I had to copy the aforementioned pair of files several times before I got the correct syntax coloring.
Be sure to close the workspace, if it's open in Eclipse, before copying the files.
This worked with Eclipse Helios.
If you want to be a little more fine grained on what you migrate, the syntax highlighting rules are the lines starting with semanticHighlighting on workspace-indigo/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.jdt.ui.prefs
Doing this, I was able to migrate my syntax highlighting from Helios to Indigo
I'm using JBoss Developer Studio 10 with the Eclipse Neon 4.6 engine.
All .prefs files are inside this path:
/workspace/.metadata/.plugins/org.eclipse.core.runtime/.sett‌​ings
Update: I found a similar structure on this path too:
\RedHat\JBossDev\studio\configuration\.settings
It's my IDE folder plus \configuration\.settings
I recommend search for org.eclipse.*ui*.prefs instead *.prefs to refine your result.
The principal config files are:
org.eclipse.jdt.ui.prefs
Java Syntax Color Settings
org.eclipse.ui.editors.prefs
Text Editor Settings
org.eclipse.cdt.ui.prefs
Formatter Settings
org.eclipse.wst.jsdt.ui.prefs
JavaScript Syntax Color Settings
org.eclipse.jst.jsp.ui.prefs
org.eclipse.wst.css.ui.prefs
org.eclipse.wst.html.ui.prefs
org.eclipse.wst.json.ui.prefs
org.eclipse.wst.dtd.ui.prefs
org.eclipse.wst.xml.ui.prefs
org.eclipse.wst.xsl.ui.prefs
If have a problematic workspace:
Copy the files above
Create a new workspace
Copy and Replace that files in your new workspace
This will recover perfectly your custom editors color settings. For me worked very well.
Eclipse CDT stores 'Syntax coloring' in the file org.eclipse.cdt.ui.prefs
This is located for example here: C:\eclipse\workspace.metadata.plugins\org.eclipse.core.runtime.settings\
Copy and paste over the top of the one in your new eclipse instance. This worked for me when moving from 3.4 to 3.5
I would export the preference before modifying the color, and then after.
That way, you would be able to isolate the specific rules of an eclipse preference file into one smaller file and:
check if some colors not restored are indeed represented by a rule
the import of a smaller preference has any effect on the previously unchanged settings.
That kind of strategy can be further refined into several small settings files (one for Java, one for JSP, HTML, CSS, ...), in order to better analyzing the potential side-effects when re-importing those settings.
I have had success in importing Eclipse Helios's syntax highlighting rules by copying the file:
.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.jdt.ui.prefs
from the source workspace to the target workspace. It seems this file also contains Eclipse's code formatter profiles and code templates.
Environment:
Version: Helios Release
Build id: 20100617-1415
(on linux)
Once Michael Bosworth's answer helped me to some extend and I voted up. But now I see some obligation to answer it myself, because copying these two files are not enough. Let me explain why.
First, these files contains lines irrevelente to syntax coloring.
Second, syntax coloring for other editors are located elsewhere, for example, those of XML files are in
org.eclipse.wst.xml.ui.prefs
and those of HTML files:
org.eclipse.wst.html.ui.prefs
JSP pages?
org.eclipse.jst.jsp.ui.prefs
, etc.
Third, when we change font colors, usually we change background colors, line highlighting colors, etc. to get a clearer view of codes. This involves more files.
If we search *.pref files in path
/workspace/.metadata/.plugins
we can find all preferences files where we can locate all lines of coloring settings. But by copy-pasting all these files to another workspace can also trigger problems, for they are not exclusively syntax-coloring-related. Moreover, when we are switching between two versions of Eclipse, unexpected problems may arise.
So, the safest way is:
Create a new workspace if you don't have one.
Open all *.pref files we find in the workspace one by one,
Copy those lines containing color codes,
Find the same file in your new workspace,
Replace the color part by existing one. Or, set the colors in Eclipse, by assuming the corresponding options according to properties' name. All color codes are RGB based.
EDIT: (2017.02.24)
Eclipse Mars has a plugin Oomph, which can record your preference settings to provide seamless transmission of your preferences. When you activate it, every time you change a value, it prompts to ask you if you want to record it in Oomph, providing you the exact line in the corresponding file where your new value is stored. So, when you install Oomph, you can:
Change the settings of your font face, font size, background color, etc.
In the prompt windows of Oomph, take note of the location of your new settings. (Because if you tell Oomph to remember your settings, it will not prompt never again, so you may only see this windows once.)
I have deleted recently changed *.prefs file from the following dreictory \myworkspace.metadata.plugins\org.eclipse.core.runtime.settings\ and imported existing exported preference.
I am the first person, who answer for this question as per my knowledge :), Cause even I struggled lot.
Thanks
I faced the same problem few days ago.
The easiest way to restore the defaults is to import the default theme again, which you can find under:
