How to connect source or JavaDoc in eclipse for any jar file, for example. JavaFX?

Question

I am currently working with JavaFX. Whenever I hover over a JavaFX method, it throws the following error:

'Note: This element neither has attached source nor attached Javadoc and hence no Javadoc could be found'

How do I resolve this? How can I attach a javadoc or source so that I can see the description of the methods?

Answer 1

You can configure Javadocs using a boot can, mainly javadocs will be transferred directly from the Internet.

Complete steps:

• Open the "Build Path" page of the project (right-click, properties, Java build path).
• Click the Libraries tab.
• Expand the node of the appropriate library (JavaFX).
• Select the location of the JavaDoc and click "Edit."
• Enter the location of the file containing the Javadoc. Specifically, for javaFX javadoc, enter http://docs.oracle.com/javafx/2.0/api/

for stand-alone javadocs, you can download from: http://www.oracle.com/technetwork/java/javase/documentation/java-se-7-doc-download-435117.html

After clicking "Accept the license agreement" you can download javafx-2_2_0-apidocs.zip

Answer 2

• Download the jar file containing JavaDocs.
• Open the "Build path" page of the project (right-click, properties, Java build path).
• Click the Libraries tab.
• Expand the node of the appropriate library (JavaFX).
• Select the location of the JavaDoc and click "Edit."
• Enter the location in the file containing the Javadoc (the one you just downloaded).

Answer 3

Neither the project / properties / Javadoc location, nor the Java project / properties / path / library helped me until I selected and went to the Order and Export tab in the Java Build Path section of Android Dependencies and added to library.jar . Hope this will be helpful.

Answer 4

Alternatively you can also

1) Go to this method with Ctrl + Click on the method. A new tab / window will open with the text "Source not found" and the button "Attach source .." in it
2) Click the "Attach source .." button
3) A new window will appear. Click "External Folder"
4) Find the javaadoc JavaFX folder. If you are on Windows with the default installation settings, the path to the C:\Program Files\Oracle\JavaFX 2.0 SDK\docs folder

Answer 5

Firstly, if you receive a message

Note. This element did not connect the source or add Javadoc, and therefore, Javadoc was not found.

Then this means that you have already turned on the external bank needed for your project.

The next step is to link the external jar to its javadoc url.

• go to the package explorer, expand the project folder, expand the library links
• right click on the external jar you want to link your javadoc with
• Click Properties → Location javadoc
• copy and scroll the javadoc url that you connect over the Internet to the javadoc location path.
• click

And you are all set!

Answer 6

First of all, the answers are correct, but there is another method that is very convenient.

Prerequisite: Your project is a Maven project or will convert it to a Maven project.

RightclickOnProject> Configuration> Convert to Maven Project

- Now follow these steps:

1 . Select any jar for which you want to download sources or javadocs.

2 . RightClick> Maven> Download javadoc or Download javasources

Answer 7

I could not get the Attach Source ... method to work, and I tried many different ways. Javadocs for JavaFX are installed in the Program Files \ Oracle \ JavaFX 2.x SDK \ docs. Another way to install Javadocs:

• Right click on the project, select "Properties"
• Select libraries on the right side of the tab
• In the upper right part of the tab, you can see "JavaFX Platform by default" or something similar. Click the "Manage Platforms" button. (You can also install this platform by default here if you do not already have it).
• On the Java Platform Manager Manager tab that appears, select the Default JavaFX Platform on the left side, and then click the JavaFX tab on the right side of the window.
• One of the input fields is marked as "JavaFX Javadoc". Click the browse button next to this field and navigate to the above document file.

Hope this helps some people who were just as puzzled as I am.

In addition to @ dhroove's answer (would write a comment if I had 50 representatives ...)

Link has changed to: http://docs.oracle.com/javafx/2/api/

At least my eclipse could not use the link from him.

Answer 9

This is already in a different thread, just a simple eclipse will automatically load the JavaDoc (but you need to click the method first).

Where can I download JavaDoc for JPA 2.0?

Answer 10

This trick worked for me in Eclipse Luna (4.4.2): for the jar file I use (htsjdk), I packed the source in a separate jar file (named htsjdk-2.0.1-src.jar; could do this, since htsjdk is open source) and saved it in the lib-src folder of my project. In my own Java source, I selected the element that I used from jar and press F3 (Open declare). Eclipse opened the class file and showed the "Attach Source" button. I clicked the button and pointed to the src jar file that I just put in the lib-src folder. Now I get Javadoc when freezing over what Im using from the jar.

Answer 11

If you are using maven just do:

 mvn eclipse:eclipse -DdownloadSources=true -DdownloadJavadocs=true 

Answer 12

You can specify the Javadoc online location for a specific JAR file in Eclipse. It saved my day when I could not find downloadable Javadocs for Kafka.

1. In the Package Explorer right-click on the proposed JAR file (under the Link Libraries or Maven Dependences project or something like that) and select Properties .
2. Click on Javadoc Location .
3. In the Javadoc location path field below the Javadoc URL, enter the URL for the online Javadoc, which most likely ends in /<version>/javadoc/ . For example, Javadoc Kafka 2.3.0 is located at http://www.apache.org/dist/kafka/2.3.0/javadoc/ (you can change https to http in your URL since it triggered an invalid location warning after clicking on Validate... for me).
