Is there a way to stop eclipse search from duplicating results - eclipse

This is a really minor issue but I thought I'd stop ignoring it and see if there is an easy resolution. In Eclipse Oxygen.2 I have a Java app with a number of sub projects which I tend to look at in JavaEE view (presumably irrelevant to the search results). When I do a file search (*.java) I get each file twice. One under parent_project\project and once under project. This is a little irritating and made more so because the intellisense and code 'go to' facilities don't work in the files displayed under parent_project\project.
I just wondered if I was missing a really obvious way to stop this happening ?

I don't know since when this feature is implemented in Eclipse, but on 2020-09 version you can use "Filter duplicated resources" on the Ctrl+R search options :

Intellij Idea highlight src with errors

I'm investigating switching from Eclipse Scala IDE to Intellij 15 + Scala plugin.
I can see that compile errors are reported in the Messages tool, but I can't see any highlighting of source files containing errors in the project tree.
Is this feature not available? If not, how do you cope? Have I been just spoiled by Eclipse and should learn to 'rough it'?
Update
This question is different to IntelliJ - show where errors are because:
This question is concerned with visual indicators against files in the folder/file tree view.
That question is concerned with indicators within the files being edited. This can be seen in the accepted answer, where the screenshot concerns editor settings for code highlighting.
I opened an issue with the exact same request when I switched from Eclipse to IntelliJ: https://youtrack.jetbrains.com/issue/IDEA-110767 !
After a while you become accustomed to look at the messages window where you get active links which when clicked, directly take you to the error.
Having syntax highlighting in the tree is nice when you refactor and hence tend to break a lot of existing code. At the same time automatic refactoring was (still is?) much better in IntelliJ than it was in Eclipse.

eclipse libraries no longer working

i had put two libraries on the build path of my project, and then i closed eclipse for the night. when i re-opened eclipse, and opened the same workspace, the libraries "aren't working" in that eclipse isn't doing any of the helpful things it was previously doing, like underlining bad syntax with red squigglies, reporting things that didn't get imported, etc. anyone have an idea of what happened?
Maybe you have disabled "Project->Build Automatically"?
Try Project->Clean. Perhaps the perspective has changed, e.g. from one language to another so it isn'd doing any syntax highlighting

Eclipse: Refreshing known types in Java project

If you press Shift+Ctrl+T or choose "Navigate > Open Type..." you get the "Open Type" dialog for quickly navigating to a known class. When you start typing a name only the classes for which the name matches stay visible. That way you can find a class of which you know the name very quick without having to browse through the package explorer tree.
This has been working great for me up until this morning. All of a sudden for a couple of my projects I am only seeing some of the types that exist. Of course I tried the obvious steps of refreshing the projects, cleaning the projects, re-building the projects, rebuilding the projects externally, but all to no avail. It is a bit odd since the types are known in other places. If I add an import statement Eclipse does not complain that it doesn't know the type and I can Ctrl-Click through the types to get to their file. However, the type navigation knows nothing about them.
In the past when InteliJ used to do this to me I would go find its cache files and delete them forcing it to rebuild. Does Eclipse have something similar I might do (I'm an Eclipse newbie)? I am using Eclipse 3.4.2 and I have it configured to not delete files on a clean (because our actual build process puts files into the output directories that I don't want Eclipse mucking with).
Have you tried closing and reopening the project? Only types from open projects are held in memory, and the refresh occurs when you Shift+Ctrl+T for the first time on a newly opened project.
Edit to add: Ctrl+Shift+R also displays the types (along with everything else) but it also supports the Camel-case thing to find the Java types quickly.
Close eclipse and delete any .index files and the savedIndexNames.txt file in workspace/.metadata/.plugins/org.eclipse.jdt.core once eclipse is restarted it will rebuildl the entire index for Ctrl+T
try starting eclipse with the -clean flag, you can add this to your eclipse.ini which can be found in the same directory as you eclispe.exe, or if you start eclipse using a bat or shell script, add it as a startup argument, e.g. eclipse -clean.
The clean will tidy your workspace, and should force eclipse JDT to recalulate types. Ive had issue with .snap files (with seem to be created on dirty shutdowns) that seem to corrupt my workspace until I clean them up, not long ago eclipse lost the Object class!! made for some interesting errors!
I get problems like this often. I tried your solution, noticed it seemed to rebuild its search index, but I still couldn't find any of my classes. Then I took a look at the little green arrow on top right corner of that dialog, and noticed I had a working set selected which belonged to another project. I find it a little dumb that Eclipse doesn't warn you about this or anything, since this can be a very annoying little detail that one tends to forget (me at least ;-)).
Anyways, clicked on "Deselect Working Set" and bam I can find my classes again. Thought I'd add this here since others may make the same mistake.
This worked for me -
Select your project in Package Explorer
Press F5 or Right click and select Refresh
I used the "-clean" as first line in the eclipse.ini (version Juno) and worked like a charm.
I'v tried all the answers and I still had the issue. I then tried this:
I deleted the project (it's a maven project) and re-imported it. This time I made sure i check the "Add Project(s) to working set" checkbox. After that Eclipse was able to find the classes in that project.
The problem must have started because I didn't check this checkbox when i first imported this project.
By the way, I'm using Neon
(Warning: Shameless marketing ahead)
If you like this feature, you would love nWire. nWire allows, among other things, to quickly search not only for types, but for any possible Java element like method or field. It also uses a navigator view which is non-modal. After searching you can see the class associations in a very quick and easy way. Check out the video on our site.

Painless integration of Eclipse with Vim?

Has anyone managed to get Vim integrated into Eclipse painlessly? I just want to use Vim for the editor while retaining the general Eclipse interface. I have tried using Eclim plugin but the editor seemed to crash more often than work (the site said that the editor replacement functionality is still beta).
On the flip side, is there any IDE which matches Eclipse's functionality—mainly the integration with SVN, ant, etc.—and is also able to use Vim?
I mostly use eclipse for SAS SCL, Java and Javascript programming and find the eclipse editor too "mouse-y".
I'd also like, in a perfect world, to use vimdiff as a diff viewer for SVN (we use TortoiseSVN) while checking for diffs or conflicts during merge etc. I admit I havent spent a lot of time trying to get these things to work. I feel guilty about spending too much time on potential wild-goose-chases while my other team members are working away at their code, perfectly content with all that Eclipse has to offer.
Edit: Just found this while desperately browsing around: Vim plugin. Any experience using this? From the claims on the site, it sounds perfect.
I've been using Vrapper for about 2 months and it works great. It is simple to install, and makes life much easier.
It doesn't integrate Vim with Eclipse, it just emulates Vim's behaviour so you don't need to have Vim installed.
EDIT:
I have been experiencing errors while refactoring methods in Eclipse (only when Vrapper was installed) so I stopped using it.
Now I'm using ViPlugin (very similar to vrapper). It works great (especially since version 2.0) and I recommend it, but it is not free (but cheap and has a trial version)
Edit
As the new post mentioned, if we always use the rename dialog to rename, it can be a work around for Varpper.
Preferences > Java > and uncheck "Rename in editor without dialog"
http://sourceforge.net/apps/trac/vrapper/ticket/96
The consensus seems summarized in that Wanted: VIM in Eclipse article.
No decent Vi plugin exists for eclipse, except viplugin which does not offer macro mechanisms.
Whereas on the NetBeans side... jvi does a killing job ;)
WOW, this is the one!
http://vrapper.sourceforge.net/home/
It just came out a few months ago, and seems much better than the other alternatives...and it is open source.
I use Viable, which is a new plugin for Eclipse providing Vi emulation. It is very similar to vrapper, but it doesn't have the same problem as vrapper with refactoring (as cysiek10 described.)
It's got some pretty cool features which none of the other Vim emulators in Eclipse seem to have (though jvi for NetBeans has a few of these) such as:
Visual block mode
External filters and commands
Command history
Window splits (love having this one!)
It is pay; however, you can try the full version for free just like viPlugin.
I never had much luck with vim integration into any IDE, be it Eclipse, Visual Studio, NetBeans, or sth else. Instead when stuck using an IDE, I just make the IDE launch a custom program: which passes the file onto vim using the client/server feature.
I.e. vim --servername SomeName --remote-{choice of how to open it: splits or tabs} {extra args like filename and +line#}
I just tried Eclim http://eclim.org/ and found it really good. I can still edit inside Vim, and enjoy most of the benefits of the eclipse IDE inside Vim (such as better omni completions).
The best thing about Eclim is we are still using the original Vim, so I can enjoy all the existing benefits (my own functions, macros, etc.) while having the extra convenience provided by an IDE.
http://vimplugin.org, which I found over the weekend was the closest I could come to a nice integration. Unfortunately when I opened more than 2 files in my IDE, it made my entire workstation unresponsive. And I didn't even use the "new process" option for the editor.
So bottom line it does seem that there is no decent integration available yet. Although with some it's close. I'm rooting for vimplugin to stabilize and I'll also some time (when I'm not eating up my employer's time like now) play some more with hte plugin to see if I can make it usable.
I tried Eclim and didn't like it at all. I ended using this plugin called "viPlugin," which actually works well enough to warrant using it every day. Here is the site for viPlugin:
http://www.viplugin.com
The big downside of this plugin is that it's not free. I paid for it, and I think it's worth it.
...is there any IDE which matches Eclipse's functionality -- mainly the integration with SVN, ant, etc. -- and is also able to use Vim?
IntelliJ IDEA has a very good VI plugin, but I didn't like it, although the plugin did it's work.
My problem was I have formed habits to use IDEA and those were harder and my experiment didn't it through. So I uninstall the plugin, and learned idea shortcuts instead.
But, is not free :(
Vrapper does the trick.
After installing Vrapper you need to remove CTRL+W key binding in Eclipse settings. Or else it keeps closing the editor when you actually meant Backspace.
It also comes with "surround" and split window plugins. Be sure to install those.
This is not 100% Vim, though. And nothing is 100% Vim except for Vim (doh!). You will find some commands missing (or you may not, depending on how "vimy" you are). But vrapper has :vim command, which opens up Vim editor with the current file in the buffer and places your cursor in the exact location in the file. This way you can continue editing from where you left off. When you're done in Vim just close the editor, and you return to your eclipse editor.
I hope this was helpful.

Eclipse's WTP translation output

How can I view the intermediate translation done to JSP and JSPX pages by WTP? I'm getting weird syntax errors in my Problems tab of Eclipse in a project that has plenty of .jspx pages. They don't affect anything in the running application (Tomcat 6.0) and they appeared only over the last 2 weeks, after an update.
The reason why I'd like to view the output is that I'm using the Stripes framework at http://stripesframework.org and the errors disappear for a particular .jspx file after I remove the <stripes:errors /> line of that file. At the same time, the syntax errors only appeared after I did recent fresh install of Eclipse at work, but then an update of Eclipse at home shortly therafter. I'd like to see the output to determine whose problem this should be (WTP, Stripes, or maybe just me :).
Remember that this issue is somewhat cosmetic, as it doesn't affect anything functionally. It simply spams my Problems tab in Eclipse and shows the little red X icons in the project explorer.
Right now you'd have to add the separate automated tests download to do this, and only in the 3.1 branch, but it enables a "Show Translation" command through Ctrl+Shift+9. Beware that the translation generated isn't 100% the same as the server would create at runtime--it's not intended to be executed. Also, the most recent 3.0.3 builds contain fixes to the translator that should clear up these kinds of problems (NESTED variables + self-closing tags). 3.0.3 is due in November and should update cleanly into Ganymede SR1.
I've seen the eclipse JSP editor get really confused over almost nothing. You said the problem goes away if you remove the tag. Does it come back if you put the tag back? I know that Eclipse 3.3 sometimes had some issues with JSP files where opening them, and forcing a save would clear the file of error messages (I haven't tried 3.4 yet). Maybe that's what's happening to you. Other than that, do you have all the proper includes / xml namespaces defined in the files?
I'm having exactly same problem with JSP and <stripes:errors/> tag in Ganymede. With Europa, there were no errors. Now it displays a couple of weird syntax errors on the problems pane. But as Silvaran stated it's just cosmetic, since the project builds correctly and works. It's still annoying though.
