I have built a library and linked it to my Eclipse project as an External JAR.
Though the library works well, I couldn't make the Javadoc I wrote appear, as Eclipse keeps showing me:
I've read through some similar posts and they all refer to the javadoc file location, but I have no separate file for Javadoc. Everything is written above fields and methods with basic annotations.
How am I supposed to "link" a javadoc that is already present in the library files ? Thank you.
You could export the jar, and in the export window you can mark the option export java source files and resources
I know this insn't the ideal fix(cause you would be exporting your source code) but it does work

I started to work on a JavaFX project in which I want to add a copied text without to change the format and images from my driver (it should work like open office). The images should be able to be placed within the text on different positions.
Therefore, I need a controlfield which can handle a rtf format.
For this purpose I found RichTextFX. In the documentation is explained how to run RichTextFX with Maven or Grandle. I dont use Maven or Grandle, therefore I would like to know if there is a possibility to run RichTextFX without using neither of them. I added the jar file to my project and copied the source code of RichtextFX Demo. Afer that i got many errors and it is not able to run.
Can someone maybe guide me trough this problem?
I already figured out how to use RichtextFX.
For everyone who wants to use RichtextFX but doesn't use Gradle or Maven here is an explanation how to run RichtextFX-Demo:
get the fat JAR file (including dependencies)
integrate the JAR in your project
copy all classes in your project from the following link :enter link description here
add the pngs and the rich-text.css to your project from the following link : enter link description here
I can't answer other questions. I hope this helps to run the Demo.
I'm in the process of writing a small Java library that contains a related code that I usually include in most of my android app. I decided to export the library as a jar file then drop the file in the libs folder of my future projects.
Using Android Studio:
I created a Java Library module and put my code in it. And I added some comments to some of the method, following this.
Then, I ran the jar task in gradle, which gave me the .jar file in build/libs directory of my module.
Now, when I used this jar in one of my android apps, Everything works as expected, except the Doc part. When I hover over the classes and methods of my library, I don't see the Doc comments that I wrote.
Q1: Am I missing another step?
Q2: Are jar files supposed to have no comments?
The javadocs are the documents that are generated from the javadoc comments in your source code. They are not part of a normal JAR file because that would unnecessarily bloat the JAR files ... with stuff that someone running to code doesn't need.
The javadocs can be generated by a Gradle task, by the javadoc command (if you have a Java SDK installed) and by various other tools. You can then read them using a web browser.
On the other hand, IDEs can often render the javadoc comments in source code and display them as pop-ups, etcetera. (Some people would call this "javadocs", but I think that is an overstatement, since you typically can't navigate the documentation ... like you can with read javadoc documents.)
In order to render the javadoc comments, the IDE needs the source code. JAR files don't (normally) contain any source code or javadocs. Instead, the normal way to deal with this is to tell the IDE where the source code is, either by pointing it at a source code directory, a ZIP file containing source code, or URL for downloading the source code.
(I don't use Android Studio, so I can tell you exactly how to do this. However, I imagine that the IDE's online help explains how to do it ...)
It seems that your end goal here is to distribute your libraries in a way that allows programmers to see the javadoc comments.
The simple way to do that is to distribute source code. This Q&A describes how to get Gradle to generate a separate archive containing the source code, or add the source code to the JAR containing your compiled code1.
If that isn't acceptable, you may need to generate the javadocs as HTML2 and provide the HTML tree as a separate ZIP file that a programmer can unzip and read with a web browser. Alternatively, put the javadocs up on a website.
1 - I would not recommend this. People who just want to use the JAR as a binary are liable to complain about "bloat".
2 - If neither providing source code or javadoc HTML documentation is acceptable, I don't think there is a pragmatic solution.
There is a separate Gradle task to generate javadoc. Try adding the following:
task javadocJar(type: Jar, dependsOn:javadoc) {
classifier = 'javadoc'
from javadoc.destinationDir }
And then run:
gradle javadocJar
See if that helps.
In addition to the above, you can try and add the following to make to generate a single jar with both compiled classes and javadoc:
jar {
from javadoc.destinationDir
}
jar.dependsOn javadoc
I don't know if that's the right decision to bundle everything in the same jar. I prefer keeping the jars separate and maybe find another way to make the IDE use the javadoc jar file. Maybe try adding the javadoc jar as another dependency of the module.
Yes This is possible
Hi, This is possible but with a small change like in the jar file.
First of all, from a code point of view jar file contains only compiled ".class" files and not source files ".java"
So if you need a doc to be applied with a jar by this I mean not the index.html which gets created but the comment that appears whenever a person uses the jar API and calls a method with a suggestion.
Example :
For that, we need to also add a source file while generating .jar file.
Steps for the same:
Type comments/java docs in code
Generate Docs
This will create a doc folder in project folder
Now create jar file
Make sure you choose this option as shown below
Almost done just test it by importing jar to another project and it should the suggestions as per docs
Very Important this can be harmful as you are including source files.java in your jar so before making make sure if you need this or not.!!!!
Hope this gave your answer

I am a Java beginner, using Eclipse. I am trying to understand the NASA World Wind package. Specifically code that looks like this:
protected WorldWindow wwd;
protected StatusBar statusBar;
protected ToolTipController toolTipController;
protected HighlightController highlightController;
When I mouse over "WorldWindow" it says
Note: This element neither has attached source nor attached Javadoc
and hence no Javadoc could be found.
The code compiles and runs, though.
However, it points to a package in a JAR file. I can find the class it is referring to. But I cannot read the class file. When I double click on it, I get "Source not found" in the Class File Editor.
I want to understand how this code works. How can I read the class files within the JAR?
Reading the actual class files in the jar would require decompiling with a tool such as JD-GUI.
However a quick Google search returned the Javadocs for the entire library.
http://builds.worldwind.arc.nasa.gov/worldwind-releases/daily/docs/api/index.html
Enjoy!
Use a decompiler - try JD-Eclipse, an Eclipse plugin. After installing it, you should be able to click on the classes you want to view and be directed to decompiled code from within the JAR file.
The project you are using is open source, so you have a few options at this point.
Ideally you can associate the source code and javadoc with the .jar file in Eclipse. This will allow you to directly view (read only) the source and documentation for the library from within Eclipse. To do this, you will need to:
download the source code and/or the javadoc. These items may very well be included in the archive you used to originally download the project (either as a jar, zip, or expanded subdirectory).
inform Eclipse about the relationship between your compiled jar file and the source/javadoc. See this guide
☆ instant gratification ☆ View the source code directly from the project repository. The World Wind project appears to be accessible at http://worldwind31.arc.nasa.gov/svn/trunk/WorldWind/src/
You can decompile the compiled code. This solution is more useful if you're trying to investigate a closed source project or if you're debugging something unusual.
You have to "decompile" the class file into readable java code. There are several good decompilers out there, here is a very popular one JD-GUI.
Also if you are using an IDE you often can download the src files and attach them just to use as javadocs while writing your program.
I'm trying to create a SWT application in eclipse. I've followed the instructions and loaded the org.eclipse.swt project to my workspace, and made it a dependency of my project by adding it to my build path.
However i cannot see the javadoc when i'm referencing the SWT libraries. I tried extracting the 'src.zip' into the org.eclipse.swt project, and then tried generating the Javadoc which created a 'doc' folder with a whole bunch of html files, so i think it's all there, it's just that eclipse isn't picking it up.
Can someone suggest anything please?
You shouldn't need to generate anything to get the Javadoc.
See if you can edit your SWT build classpath entry and attach the src.zip there. That should be enough to display the associated javadoc (like in this tutorial, except you can reference an external file src.zip instead of the external 'src' directory).
You shouldn't need to extract the zip or generate the Javadoc. I assume you followed the instructions listed here:
Developing SWT applications using Eclipse
I followed the same steps and was able to view the Javadocs in the Javadoc view tab. The tab is automatically updated whenever you click on a class you are instantiating in your code.
I just downloaded Eclipse several hours ago, and needed to add Java3D to the classpath. Installing it went without a hitch, but Eclipse can't seem to find the documentation folders so that it can give super-IDE functionality, such as autocomplete and method signatures.
While I know how I would add them individually, this lead me to the question; what is the "correct" way to install a Java library in Eclipse? Is there a special directory format I should follow? Is there a plugin that already did this for me? (The answer to that is yes, but I don't know how to use it, or whether or not it's appropriate).
Thanks!
Edit 1: It seems to me that someone down-voted the question. May I ask why?
Edit 2: So after monkeying around with the JARs, it seems that manually setting the doc path for each JAR in the library seems to be the least-error prone way.
when you add a .JAR(library) to your project in the LIBRARIES tab for your project, you have the option of attaching the javadoc directory for the jar.
So, go to the LIBRARIES tab of the "java build path" for your projects. select your jar. expand the (+) sign and you will see that you can set the javadoc. path.
good luck,
I think I've got it (had the same issue as you). Better late than never.
Go here - http://java3d.java.net/binary-builds.html and download the documentation zip (j3d-1_5_2-api-docs.zip).
Extract the directory anywhere on your HD (Right in the Java3d folder is fine).
Link the Jar's JavaDoc listing to that Folder (java build path >> Libraries >> expand the Jar Listing >> JavaDoc Location >> browse to the folder location, then validate). Do it for each j3d Jar.
That should integrate the J3D Javadoc.
As far as I know (haven't used 3.4 very much thus far), Eclipse has two options for the automatic showing of Javadocs. The first is a JavaDoc jar to attach to the jar file. The second is having the javadoc in a source jar which is attached to the jar to show the source.
A directory, if I recall correctly, will not provide autocompletion of javadoc. However, if you press "F1", you will be able to access the javadoc via the help menu.
You might try placing the documentation directory into a jar file, and attaching it to the jar file and see if that tricks Eclipse.
I cheat; All my java projects are built with maven, so I use maven to generate an eclipse project, with classpaths etc already setup, with a simple 'mvn eclipse:m2eclipse'.
