Before you close this question as a duplicate: I am very well aware of answers like this.
However, the Quick Doc only provides the type information, like Class and so on.
This is because the jars we have no JavaDoc in them (When I Ctrl + B into them they don't have any JavaDoc).
With jars, I don't mean some internal ones, but rather Objects like String or List, which would provide a JavaDoc in Netbeans, but in IntelliJ that Doc is just missing.
Can you enable it somewhere that JavaDoc gets loaded with the jars?
Quick Documentation feature works using the sources attached to the JDK configuration like this:
Try to reinstall the JDK, remove it from IntelliJ IDEA and add it again. Double check src.zip is added in the Sourcepath.

I have some problems with Netbeans IDE. I installed v. 7.0.1, but now the pop-up windows of the javadoc say:
Javadoc not found. Either Javadoc documentation for this item does not exist or
you have not added specified Javadoc in the Java Platform Manager or the Library
Manager.
Why didn't it auto-download the JavaDocs? I'm talking about component, method etc etc.. of Java Platform SE.
Go to Tools -> Java Platforms
Select the platform that you want and go to the javadoc tab
and the url to the javadocs. either http://docs.oracle.com/javase/6/docs/api/ or http://docs.oracle.com/javase/7/docs/api/
I believe JDK include javadoc in it But something went wrong either at the time of installation or later. So I solved this issue using these steps:
Goto
Tools >> Analyze Javadoc
An Analyzer tab will appear with the method/s that you defined and have no javadoc.
Select its checkbox and Fix Selected Button will enable press that button and problem is now gone.
In my case removeAllRows() is the method that has no javadoc.
For further check this image
.
It does not create missing javadoc for your own methods But also fix javadoc for predefined methods.
If this does not solve your problem than you should try adding javadoc manually.
I am having a weird problem with intellij. A handful of people in here, had similar issues in the past but none of the proposed solutions worked for me.
So I am trying to view the javadoc for a builtin class(in my example java.io.FileReader) but I am only getting information about the signature, not details about the method as it is usually happening. I have also tried things around quick and external documentation, I have even added an external doc url in the project settings but nothing happened.
In the screenshot you can see the output I am getting. Any help appreciated.
Looks like Eclipse uses a different approach for the documentation. Also I had a non-fully document API and thats, combined, the reason it was not working.
The solution is as follows: File -> Project structure -> SDKs -> Documentation paths -> Click the add button, with the earth on it -> Add an online documentation source.
If you click the other one, you need to space a folder in your filesystem.
Both work. Thank you for your help.
Ctrl + Q
This assumes you have the JDK (with documentation) downloaded and configured with IntelliJ for the relevant object/class/method.
Edit:
Turned out it was a problem with the Users' JDK.
The JDK source files didn't contain any comments (which IntelliJ uses to show JDK Documentation). This was resolved by installing the JDK Documentation and configuring it with IntelliJ.
I have the JD-eclipse-plugin installed. I want to decompile the classes within a jar-file. So I select the jar-file within Project-Explorer and click Decompiler in the Menu. However both decompilers (JAD and JD-core) are greyed out.
I also tried the steps shown in this blog on AVAJAVA Web Tutorials. I guess the blog is a bit outdated, however I can see within Windows-->Preferences-->Java-->Decompiler that Jad is correctly set up. But there is no JD-eclipse found within Preferences-->General-->Editors-->File Associations as you can see in the following image.. Now I right click the jar-file within Project-Explorer, but there is no such "Attach Source File".
Did I miss anything to set up the plugin?
EDIT: I´m using the following setup: Eclipse: Mars.1 Release (4.5.1); JadClipse 4.0.0; JDK 1.8
EDIT2: Forgot to mention that I use Tomcat and want to dive into the libraries from /WebContent/WEB-INF/lib. This is not working, I cannot further collapse the jar-files.
For Eclipse 2018-09 , the problem was related to " class without source
"
I had resolved this issue by going to:
Preferences
General
Editors
File Associations
Class without source
and setting decompliler viewer as default : see the following screen shot:
Obviously I mixed the actual JD-eclipse-plugin an a plugin called JadClipse for Eclipse which is a slightly different plugin from eclipse marketplace. Thus when I followed the installation instructions of JD-eclipse, I could set the options for the screenshot posted within the question. So I set JD-eclipse as default for both *.class-files with and those without source-code.
Second mistake I did was a pretty silly and obvious one, namely that I wanted to browse the jar-files from within WEB-INF-folder of my Tomcat instead of from within Java Resources. Thus I could not dive into the jar-files at all hindering me to get to the class-level and thus to decompile those classes contained within the jar.
I hope this helps anyone outside also having trouble with the plugin for eclipse.
I had the same problem but "class without source" did have decompliler viewer as default. So all I did was set class file viewer as default and then switched back and that fixed the issue.
I had to update all of my plugins. the Procyon decompiler has this symptom when running under java 11 or later.
I'm working on big Java enterpriseware (MatrixOne / ENOVIA V6, if you mind). The maintainers provide some kind of Javadoc, which looks like very vanilla Javadoc, and I can read it as HTML in my browser.
However, I'm unable to integrate it to Eclipse, which is painful because I have to make round-trips to my browser. In Eclipse, I just get the dreaded Note: This element neither has attached source nor attached Javadoc and hence no Javadoc could be found.:
After learning that Javadoc can be defined at project and .jar level, I tried to do both, knowing that:
the javadoc folder contains a package-list file, which seems to sanely define the documented packages
the javadoc folder contains the typical folder/subfolder package structure, itself containing ClassName.html files. E.g. the com.matrixone.apps.domain line of my package-list file is matched by a com/matrixone/apps/domain structure, containing lots of ClassName.html files
the javadoc folder doesn't contain a index.html file
When I try to define my Javadoc, the Validate... button fails because of a missing index.html. Then if I create a dummy index.html file, validation works, but I still cannot see the Javadoc when hovering a vendor class/method.
So my question is: What's missing to get this skewed Javadoc to display in Eclipse? Sub-questions I see at this point are:
Was it a bad idea to create a dummy index.html file? If yes, what should I do? (i.e. what tags/meta-information does Eclipse expect?)
A quick comparison of a standard Javadoc file (String.html) vs. one of those vendor Javadoc (DomainObject.html) reveals that meta-information possibly used by Eclipse is absent from my javadoc. For example, my vendor Javadoc includes none of the many <meta> tags present in the String.html Javadoc <head>.
→ Does somebody know the logic/heuristic used by Eclipse to fetch a method/class Javadoc? Maybe point me to the code? With this information I may be able to figure out what's wrong in my Javadoc, and hopefully fix it.
Anything you see fit if you ever faced a similar problem.
I'm currently using Eclipse Juno SR1 on Java 7, under Windows 7.
Of course, feel free to comment to ask for information I forgot to include. Thanks for your help!
I had a similar problem; however, I didn't try to solve it by using a local copy of the JavaDoc for JDOM. Instead, I was trying to use the appropriate URL (the JavaDoc URL for the current version of JDOM is http://jdom.org/docs/apidocs/). So, on the jdom.jar library in the Java Build Path configuration for my Eclipse project, I configured the URL and hit the Validate button. Eclipse seemed to think it was valid, but I still got the same error about not having any attached JavaDoc.
I then discovered that jdom.org also has the JavaDoc for an older version of JDOM (http://www.jdom.org/docs/apidocs.1.1/). So, I tried that on the jdom.jar library JavaDoc configuration and that worked!
The lesson I learned was that the version of the library appears to be taken into consideration when Eclipse is deciding whether the configured JavaDoc is utilized (considered to be attached or not). Make sure the library version matches the version of the JavaDoc for the library (seems obvious now that I've found it).
Hope this helps.
I have a problem with Eclipse Indigo regarding library source code. When I open a library class (e.g. from the JDK, but also from some other included libraries, such as Guava), either using the Open Type dialogue or simply through Ctrl+ click on the class name or some of its methods, once in a while (not always) something breaks.
Don't get me wrong, the source is always displayed without any problem (either JDK source shipped with the JDK itself or Guava source downloaded by Maven). What actually stops to work:
When I open the Quick Outline popup in that given class using Ctrl + O, the list of methods and fields displays normally, but when I click on any of them, Eclipse doesn't move the view on it as it should. Also Ctrl + clicking any of the methods or fields of that class in my code doesn't bring me directly to it, but simply at the top of the source file.
When I hover over that said class or its methods, no JavaDoc appears in the popup as you can see in the attached image. I am in the HashSet class, the source is clearly there, but it isn't displayed in the popup.
I found out that this can be fixed by opening the Outline View and briefly clicking through the class's methods and fields. After a few clicks, Eclipse catches on and starts to work correctly, but only for this one class, not for all which are broken in this way at the moment.
Has anybody met this kind of bug? Is it tracked at Eclipse Bugzilla? Thanks in advance for any advice.
For completeness, this is my configuration:
Windows 7 Professional x64
Oracle JDK 1.7 Update 2 32b
Eclipse Indigo for Java EE Developers 32b
your issue #2 may be resolved by following these steps :
Go to http://java.sun.com/j2se/1.5.0/download.jsp and choose to
download the JDK 5.0 Source Code.
For JDK 5.0, select Download(SCSL source).
Download JDK (SCSL) 5.0 (1.5.0). This will give you a file jdk-1_5_0-src.scsl.zip. You do not need to unzip this file; Eclipse likes it the way it is.
In Eclipse, go to Projects -> Properties -> Java Build Path -> Libraries and expand JRE System Library [jre 1.5.0], then rt.jar. Select Source attachment and click Edit...
Select the above zip file. and Finish by exiting the dialog boxes.
source
Hope this helps..
Sounds like wrong sources are attached to the libs inside Eclipse.
I had similar symptoms in a project where a class exist in both: inside a lib and in the project's src folder. Same canonical class name, but different implementations.
I would recommend to verify (or reinstall) your JDK-Installation and re-configurating it in Eclipse.
Hitting Ctrl+Shift+T and typing HashSet and taking a screenshot of that window may help here, too.
To answer my own question, I didn't find out how to solve the problem in Indigo, but updating to Juno fixed it.
