I have a Eclipse project.
I am searching for a way to generate code-templates that will appear automatically when I am adding a file to the project.
For example, I want to add a documentation code-template (eclipse's template is-
/**
**
** #author:
**/)
such that it will automatically appear in each java class file I add to the project, without making it manually.
Is there a good way to do so?
You're able to change this behavior in
Window -> Preferences -> Java -> Code Style -> Code templates -> Comments -> Files
Sharing #howlger answer:
In eclipse - Window>Preferences>Configure Project Specific Settings> choose project and then ok , then add any code-template you want.

I'm having trouble getting Eclipse to index my source code. I'm using Eclipse Helios on Windows XP at the moment.
I have a directory called src. Within it, I have a bunch of dirs, something like this:
src
-include (common headers)
-lib
-libIO (source code for this library)
-libGUI (source code for this library)
-pgms
-pgm1 (source code and headers for this pgm)
-pgm2 (source code and headers for this pgm)
Each leaf has its own Makefile. There is no top-level Makefile in src. pgm1 can and does include files from include and lib/libIO and lib/libGUI.
Basically, I want Eclipse to index my entire src directory, without having to set up a C/C++ project for every leaf in my tree. I can't seem to find a way to make this happen.
Here's my symptoms; what I'm trying to solve for:
When editing source in the pgm1 dir, it references functions that are declared in my include dir header files and defined in source files found in lib/libIO.
However, when I press F3 to get to the declaration of a function, Eclipse says "Could not find symbol 'X' in index". I can't seem to get Eclipse to find either the header declaration or the source definition for the method under my cursor (like the Java module does perfectly). Is this possible?
I had exactly same issue as OP but for some reason the menus in Eclipse I was using (Helios Service Release 2) were not "Go to Properties -> C/C++ General -> Paths and Symbols -> Source Location.".
The way I fixed the issue was :
in C/C++ view, right-click on top project name;
in the menu, select New->C++ Project;
in the window that appears, select Convert to and then select C++ project;
click OK to close the window.
Eclipse will start indexing right away. Depending on the size of source tree it may take a while but you will have the indexing working finally after that.
I faced similar situation. I solved it in this way: right-click the project in project View-->select Index-->rebuild.
I managed to solve this thanks to comments here.... I ended up recreating my project. I used the Import method to download a project from CVS, and told it to use the New Project wizard to do so. When I got the New Project dialog, I told it this was a C++ Project, and the indexing now works fine.
I still wish I could index files without having to attach a specific project type to it, but at least I found an answer.
Thanks for the help all.
Exit Eclipse. In workspace go to ".metadata/.plugins/org.eclipse.cdt.core" and delete everything in there.
in the project explorer panel, right click the project you want to re-index, then select index, then select the action you want
Indexing of files and variables under different flags is always complicated when we have a huge project, lot of files and more importantly lot of different build options. I prefer playing around with the Indexer option to help me browse the entire code.
You can find it : Project Properties>C/C++ General/Indexer.
You can choose "Enable project specific settings"
Then it's up to you to choose the options you want for your project.
For a particular build we can choose "Use active build configuration" so that only the files and MACROS are considered which are used by the build script.
Or Index all source files in the entire project.
I am using Eclipse Neon 3, here's the solution that worked for me :
go to File
New
Convert to C/C++ Autotools project
then select your project and finish.
It can take some time to finish indexing, it depends on your project size.
I have experienced problems with the indexer of Eclipse Luna when there was an unresolved friend declaration in the class declaration - it seems then that the indexer skipped indexing the rest of that class, and all references to it was shown as unresolved by the indexer.
Solution: removed the unresolved friend declaration (in my case, it was legacy code that was no longer needed).
Please try the following (my project is set up differently, so I am not sure this will work for you).
Go to Properties -> C/C++ General -> Paths and Symbols -> Source Location.
Do you see your source folder there?
I observe this behavior:
When I add a source folder and then exclude it from build, it disappears from the above list. After that the folder is no longer indexed. Re-adding it to "Source Location" solves the problem: the folder is now indexed; remains excluded from build (as intended); is visible among source locations.
I believe it is a bug -- excluding a source folder from build should not remove it from source locations list.
In Coocox IDE (Eclipse + gcc) the problem is resolved by going from file menu
Edit > Preferences > C/C++ / Indexer > Build configuration for Indexer set to Active build configuration and the rebuild the project (Ctrl R).
If the project is already converted to C/C++ and still the index is not working you can right click on the project and Index and rebuild. The project will start indexing right away.
I am using
Eclipse IDE for C/C++ Linux Developers
Version: Helios Service Release 2
Build id: 20110218-0911
I followed the suggestions above and in addition I had to mark all referenced projects (with in the work space) using project properties->Project references
The following has worked for me in Eclipse Neon:
New Project -> C/C++ -> Makefile project with existing code -> Next. Then Navigate to the code and finish the project creation. Indexing starts automatically.
I'm trying to figure out how I can have a comment header automatically added to all new source files in my eclipse java project. I've looked around but I haven't found a simple solution to automate this process. I gave JAutodoc a try, and even though it does allow me to specify a header I still had to tell the plugin manually to inject the header and it didn't seem very fond of my keyword-subsitution.
I'm by the way using the Maven2 plugin for Eclipse for most of my projects if that's any help.
Any tips?
Comments generation is configured in:
Main Menu -> Window -> Preferences -> Java -> Code Style -> Code Templates -> Configure generated code and comments
You can change directly the New Java files template:
Code -> New Java files -> Edit
As of Eclipse 3.6 version, it is already configured that for new Java files ${filecomment} is inserted, so it is probably better to edit it instead:
Comments -> Files -> Edit
If you want to add your comment a the top of the file (to add a copyright header), give a try to Eclipse Copyright Generator. There is a wizard that ask you what you want to include. Therefore you can add every kind of comment header.
After installation you get a new menu: Project > Apply Copyright....
In the include files field enter *.java to reduce the set of files.

As indicated in the comments, there is an other tool provided by the Eclipse Fundation: Eclipse Copyright Tool (as part of their releng tools)
I have noticed that autocomplete is not working in some of java files in Eclipse.
Also, the files where autocomplete is not working, display a hollow "J" as the icon for the Java file. The files where autocomplete is working, icon for java file is a filled "J"
I am wondering if someone can point out what went wrong all of suddent, why the change in icons and why autocomplete and syntax highlighting is turned-off in the files with a hollow "J" icon?
Thanks.
update
Basically, I was doing what VonC has suggested but Eclipse was not refreshing that it why I was thinking that VonC's suggestion isn't working, after doing a refresh, the problem resolved.
Since this question is highly ranked on Google, I will add a solution to fix general auto complete issue, not for 'hollow J' ones.
Try Window (Windows/Linux) or Eclipse (OS X) -> Preferences -> Java -> Editor -> Content Assist -> Restore Defaults
also
Content Assist -> Advanced -> Restore Defaults
some answers (restore defaults) above do not work for some adt bundle installs as of jan '13.
in those cases, go to
Window -> Preferences -> Java -> Editor -> Content Assist -> Advanced
and tick on the JAVA PROPOSAL options.
In this following picture, MyClass.java has a hollow J, because it is explicitly excluded from the sources to build:
Could you go to the properties of the project, "Java Build Path" Section, "Source" tab and see if some exclusion filter has been set ?
It is usual for instance to define:
**/Test*.java
to exclude at first building any unit-test class (when you have a large set of sources and do not want to be presented with Test classes during auto-completion, or do not want them considered during source searches).
Those with a hollow J aren't part of the build path of the project, so they can't participate in the normal build process and therefore auto-complete won't be enabled for these files (and other Java editor features!). You must add the folders with the Java files to be built to the build path using the 'source path' section of the project properties. This can be accessed by right clicking on a project in the project navigator / package explorer and going to Properties. See http://www.informit.com/articles/article.aspx?p=367962 for details.
Additionally, if the files aren't part of a Java project in the first place, you must create a project and move the files in, or put the files in an existing one. Again, make sure these file are under a source directory as described by that section of the project properties.
(source: teradata.com)
I cope with the issue by deleting the file if autocomplete does not work. Just before copying the source code. Then I have recreated the java file with the same name. Pasted the source code previously copied.
As an addendum to the #VonC answer, make sure that the Java files are part of the Inclusion pattern. I had a case where a build process was creating the project while only including .js files and not the Java files:
You can manually edit the inclusions via the Edit button. In my case, a fix was made to the build script to make it permanent.
Neither Restoring Defaults or my build path (file was already in package directory w/other files where auto-complete was working) fixed problem. Fix for me was to close the file explicitly (right click on file name in tab) and re-open. Interestingly, just re-starting Eclipse didn't work either.
Make sure you have the right directory structure. I believe that:
Hollow J icon beside Java file - will not be build
Normal J icon beside Java file - is a file to be build.
I made a mistake when I created webapp artefact. By default it does not create folder for Java, but for resources. I mistakenly put my sources there.
Have a look - see the difference.
I was able to get this fixed in Visual Studio Code, VSCode but entering crtl-shift-p and typing in clean. When I did that I ran the "Java: Clean Java Language Sever Workspace" command. This fixed my autocomplete issue for me.
I work in a group project and after every checkout
I have to remove and add the javamail api..(because the path is relative)
how can i make it IN the Project folder?
This is how i add the library :
right click on librarys folder
Add/jar Folder..
Choose the mail.jar
But when my collegue checks this out... he get's problems.
How can i make the path absolute ?
This worked for me: Project Properties -> Libraries -> Add JAR/Folder, and in that dialog there is a "Reference as" option. Choose "Relative Path" and then locate your library.
A better way to add library to Netbenas would be
Tools -> Libraries -> New Library...
After it:
Project tab -> [your project] -> Properties -> Libraries -> Add Library
This would be always "relative"
You might be better off using a dedicated folder for your libraries. Please see this tutorial to help doing the same. That way, the libraries can always live in their own country.
Is there a way to get PHPUnit auto-completion to work in Eclipse PDT without including the libraries in your project?
Have you tried putting the PHPUnit code on your project's include path?
How do you add a PHP framework to code completion/assist in Eclipse PDT and can the framework be added as default for all projects?
Generally speaking in Eclipse, you can add a library or framework to code assist/completion by:
Going into Project > Properties
Under PHP Include Path, pick the "Libaries" tab.
Add an "external folder" with the path to where your framework is
located.
You need to enable it.
Go to menu: Window -> Preferences. Then under PHP -> Editor -> Code Assist. From under auto activation check the enable auto activation check box (note: 200 ms default is a bit slow). You can adjust the timing.
