For debugging it is often helpful to read the library's source code. When pointing at a library function which I want to inspect and opening the context menu and click on 'Open Declaration' in my own written code I will just have a look at the corresponding header file.
How do I show the corresponding source/cpp file in Eclipse?
If I just search for the file in the source folders (using OS tools) I can't use Eclipse methods like 'Open call hierarchy', so, that won't be a satisfying solution. Thanks.
You can tell the debugger where to find source files. In the Run or Debug Configurations dialog, there is a Source tab when you select a particular configuration. That's where you can specify so-called Source Containers.
For more details, see the Eclipse CDT help page.

In a Dynamic Web Project in Eclipse I have a Tomcat9 attached as a Targeted Runtime (I downloaded binary distribution from official site
But if I press F3 on any class (say, SimpleTagSupport class) no source code appears because it is not attached.
How to add source code?
I understand I can download source code distribution
And I understand how to add source code:
In my case ( SimpleTagSupport ) it is
But can I somehow attach source code to all jars in Tomcat Targeted Runtime? It is a tiresom work to manually find source and attach it to each jar!
Besides I cannot find needed source-folders for all respective jars, b/c source distributions looks like this:
Also it turns out ot be that java/javax/servlet/jsp/tagext folder does not contain any valid source files, but what shall add as source to servlet-api.jar or for javax.servlet.jsp.tagext package (for SimpleTagSupport class)...
The idea is that for every .jar (for example for servlet-api.jar) you specify entire src.zip file (Eclipse will figure out the needed part itself)
Solution is found here
Use: https://javaee.github.io/javaee-spec/javadocs/
If we add source files then besides opening source by F3 it also enables tooltip (javadoc) help (taken from javadocs inside source files) on hover (or F2), but Shift+F2 would not work.
To enable Shift+F2 we need to explicitly attach Javadoc (attach source is not enough for Shift+F2).
Download Tomcat's Full Documentation (not source!!!), unarchive it and then use file:/// notation:
file:/K:/SERVERS/apache-tomcat-9.0.16-fulldocs/tomcat-9.0-doc/servletapi
Now Shift+F2 is enabled!
I am running Eclipse Mars.1 and a recent (latest?) Eclipse CDT on Fedora 23. I have a Java project and want to use C/C++ for media support. However, I can't get the IDE to create the first C file (or the second for that matter). I have created a new source folder under the Java src folder and verified that it has been created in the file system. When I R-click on that new folder and ultimately selected 'create C/C++ source file', I am presented with a 'New Source File' dialog with 2 edit fields. One is titled 'Source folder' and the other 'Source file'. No matter what I do in the 'Source folder' edit field, a status message displays that the folder doesn't exist. When I enter a file name the status field states that I haven't specified a directory. When I use the browse button to try to select a directory, nothing is displayed except a status message that says that there aren't any entries. I have enabled the C/C++ perspective, but that didn't make any difference.
I originally posted this message on the Eclipse CDT forum but didn't get an answer. I have also posted it on the Eclipse newcomers forum.
Any help or insight to resolve this difficulty would be greatly appreciated.
Java and C do mix well through the JNI. I will implement my backend media in GStreamer, so I don't really have any option. I want it to be portable to Windows, Linux and Android (iOS later). I know that the UI will be different on Android.
I did find the answer here -> http://help.eclipse.org/mars/index.jsp?topic=%2Forg.eclipse.cdt.doc.user%2Ftasks%2Fcdt_t_new_cpp.htm
I had searched for the answer earlier but never found it. I think that the key was to highlight the actual Java project (not the destination directory) in the project explorer pane, then R-click/new/file. I was able to select my folder that I had created before for the C files under the project and did successfully create and have now edited a C file.
I'm using the Android Developer Tools wrapper of Eclipse, and the EGit git plugin for Eclipse. I'm having a problem where I'm generating Javadoc, but I can't find it in the package explorer.
I go to Project->Generate Javadoc.
I'm using C:\Program Files\Java\jdk1.7.0_51\bin\javadoc.exe as my Javadoc command, and I select the package I want to generate Javadoc for.
I select the standard doclet with the following destination, where ReverseSentence is my package.
C:\Users\myname\workspace\ReverseSentence\doc
I check "open generated index file in browser", and generate the javadoc. It generates the Javadoc with no errors, and the index shows up in the main section of eclipse. However, the files don't show up in the package explorer.
I searched in the workspace through opening up the folder, and inside workspace\ReverseSentence there is a folder doc, which contains the proper Javadoc. However it isn't showing up in the package explorer.
How do I make it show up in the package explorer? When I used the regular version of Eclipse in the past (not the android developer tools wrapper), the Javadocs showed up there automatically.
What I've tried:
refreshing the project
closing and restarting eclipse
generating the Javadoc with an older version of the Javadoc command, which was what I was using in the other version of eclipse last time it worked (jdk1.6.0_43)
deleting the doc folder, recreating it, then trying to generate the javadoc in it (it generated in it but did not show up)
unchecking the filters which hide some things in the package explorer, (as shown how to do here: How can I get Eclipse to show .* files?)
I think that the problem is the destination folder/directory for your Javadoc files once they are generated. I encountered this same problem and discovered (finally) that the Javadocs were getting sent to a different folder than my package files were in. They went to the workspace folder I thought held all of my code also, but the code was going into a different repository. Maybe try looking for your code's location and then seeing if the generated Javadocs are landing somewhere else when they are generated. If this is the case, then the fix is to regenerate and send to the code's directory. This way, Package Explorer should be able to find and display them. Hope this helps!
Did you try by refreshing the workspace or re-opening the eclipse !?
Check the filters in the settings of the explorer. If something does not show up, usually the filter hides it. The filter can be accessed in the drop down menu of Package Explorer.
I am a newbie to Eclipse. I have some plug-ins installed in my eclipse workbench along with their source plugins (thus i have attached code with these plugins).
How can I open(and view) the source code of these installed plugins and set break-points so that I could debug these plug-ins?
My motive behind this task is to get a deeper understanding of the source code of some of these plug-ins.
Though the post How to set a breakpoint in Eclipse in a third party library? explains some methods, it doesn't tell how to open and view the attached source code.
Thanks in advance.
If you only need breakpoints, use Ctrl-Shift-T (Open Type), enter the name of the class and set the breakpoints.
But if you really want to learn about the plugin in question, there is more: Open PDE perspective, there is a view "Plugins". Select the plugin you are interested in, choose Import->As Source from the context menu of the plugin. This imports the plugin into your workspace, so you can really investigate all artifacts inside, not only the source. By default, your launch configuration will use the plugins from the workspace as first choice, so you can even modify that imported plugin now and see the effects when running your workspace.
How do I get eclox working in Eclipse 3.5?
I'm using Ubuntu 9.04. I installed Doxygen from ubuntu repositories(version 1.5.8). Then I installed eclox on eclipse through the update site.
Despite this, I don't get any option to in any menu to initiate it.
Also the eclox site doesn't seem to have any "getting started" guide.
Please help.
BTW there is a manual inside org.gna.eclox_0.8.0.jar, wierd they did not post this on the project site!!!
Here is the content
Eclox, a Doxygen frontend plugin for Eclipse.
<http://gna.org/projects/eclox>
INSTALLATION
There are two options to install the plugin: using the update site or
using the packaged feature.
The update site is the more convenient way to install eclox. It is
located at https://anb0s.github.io/eclox. See eclipse's user
guilde for additionnal details.
When using the packaged feature, you must extract the archive content into
your eclipse's root location. For additionnal details, please refer to
eclipse's user guide.
CONFIGURATION
Once the plugin installed, you must ensure that the default PATH environment
variable makes the doxygen binary reachable for the plugin. If not, you can
update PATH to include to directory containing the Doxygen binary, or you can
tell Eclox where that binary is located on your system (which is in my opinion
the better solution). To do this, open eclipse's preference edition dialog
window and go into the new "Doxygen" section.
USAGE
You can create new Doxygen projects (also called doxyfiles) using the
creation wizard. Go to "File->New->Other->Other->Doxygen Configuration". Press
next and set both file location and name. Then a empty doxyfile will be
created at the specified location, the wizard automatically adds the
".Doxyfile" extension.
You should now see a file with a blue #-sign icon. This is your new
doxyfile. Double-clicking on it will open the editor. You can now browse and
edit the settings.
Once your have properly set all doxyfile fields, you can launch a
documentation build using the toolbar icon showing a blue #-sign. In
the case the button is not visible in the toolbar, your current perspective
needs to get configured. Go to "Window->Customize perspective->Commands" and
in "Available command groups" check "Doxygen". Additionnaly, you can browse
the laetest builds by clicking the down arrow right to the toolbar button.
When the documentation build starts, a new view showing the build log opens.
In its toolbar, a button named "Stop" allows you to halt the current build
process. The current build also appears in the Eclipse job progress view and
you can control the job from there.
The build toolbar action determine the next doxyfile to build depending on
the current active workbench part (editor or view) and the current selection
in that part. For example, if the active part is a doxyfile editor, the next
doxyfile to build will be the one being edited. If the active part is the
resource explorer and the current selection is a doxyfile, that doxyfile will
be next to get build. In the case the active part selection doesn't correspond
to a doxyfile, the last built doxyfile will be rebuiled. And if the build
history is empty, you will be asked for the doxyfile to build.
HTH Anybody
Never mind, worked it out my self.
First you need to create a DoxyFile (which is the configuration file) by giving the source path and the output path.
Then only you can generate the documentation by right clicking the project and selecting the "Generate Documentation".
Thanks anyway!
I just faced a problem setting the Doxygen binary path in eclox 0.8.0 settings in Eclipse on Mac OS X 10.7.
There is no way to configure the path via Eclipse-preferences->Doxygen.
The solution is to edit the preferences file manually
add a (fake) location, let's say /Applications, using the wizard mentioned above.
close Eclipse
edit this file:
$WORKSPACE/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.gna.eclox.core.prefs:
Replace the value for doxygen.default (currently eclox.core.doxygen.CustomDoxygen /Applications\n) with eclox.core.doxygen.CustomDoxygen /Applications/Doxygen.app/Contents/Resources/doxygen\n.
restart Eclipse
For MacOS user there is a very easy way to get around via the issue of the Doxygen version selection. The link that provides details is here:https://github.com/theolind/mahm3lib/wiki/Integrating-Doxygen-with-Eclipse
After installing the Eclox plugging:
1)"go to "Eclipse --> Preferences --> Oxygen"
2)"Press Shift+CMD+G then Add: "/Applications/Doxygen.app/Contents/Resources/doxygen"
3) Doxygen's version should be displayed
this might help you or any windows user trying to install eclox:
Tutorial for Installing eclox — Document Transcript
Step 1: go to eclox website (http://home.gna.org/eclox/) and to copy the update link address.Step
step 2: Insert the link into the update manager in eclipse and press OK.
Step 3: Select the Eclox item and to complete the installation.
Step 4: When the installation has done, you should select a project that you want to generate thedoxygen documents. Then, create a doxygen project for it.
Step 5: config the options. Note: You have to provide the “Input directories” correctly and to select the “Scan recursively”item. Finally, save the configuration file.
Step 6: find out the “#” and to choice “Choose Doxyfile...”.
Step 7: select a doxyfile.Step 8: wait for few seconds and the doucments will be generated.

Like claus I had to dig into the preferences file maually, because eclox 0.8.0 would just not take a good path from Eclipse Preferences file chooser.
So, edit this file: $WORKSPACE/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.gna.eclox.core.prefs and alter the given path (in my case I had to change from
doxygen.default=eclox.core.doxygen.CustomDoxygen C\:\\Programm Files\\doxygen\\bin
to this
doxygen.default=eclox.core.doxygen.CustomDoxygen C\:\\Programme\\doxygen\\bin
Hope this helps.
I find a webpage https://github.com/theolind/mahm3lib/wiki/Integrating-Doxygen-with-Eclipse where you can find more details. Especially, for Mac users, you need to Press Shift+CMD+G then Add: "/Applications/Doxygen.app/Contents/Resources/doxygen" when you configure the doxygen in eclipse before compiling .doxygfile by using Eclox.
Alternative from eclipse is to use Javadoc:
From menu (...Search Project Run...)
Project > Generate Javadoc
You should be in Java project and add comments with tags.
