How to generate Javadoc from command line

Question

Can anybody show me how to generate Javadoc from command line?

My project contains the package com.test and I want to put the generated documentation in files located in a specific folder like this: C:/javadoc/test.

Answer 1

You can refer the javadoc 8 documentation

I think what you are looking at is something like this:

javadoc -d C:\javadoc\test com.test

Answer 2

Oracle provides some simple examples:

http://docs.oracle.com/javase/8/docs/technotes/tools/windows/javadoc.html#CHDJBGFC

Assuming you are in ~/ and the java source tree is in ./saxon_source/net and you want to recurse through the whole source tree net is both a directory and the top package name.

mkdir saxon_docs
javadoc -d saxon_docs -sourcepath saxon_source -subpackages net

Answer 3

Let's say you have the following directory structure where you want to generate javadocs on file1.java and file2.java (package com.test), with the javadocs being placed in C:\javadoc\test:

C:\
|
+--javadoc\
|  |
|  +--test\
|
+--projects\
   |
   +--com\
      |
      +--test\
         |
         +--file1.java
         +--file2.java

In the command terminal, navigate to the root of your package: C:\projects. If you just want to generate the standard javadocs on all the java files inside the project, run the following command (for multiple packages, separate the package names by spaces):

C:\projects> javadoc -d [path to javadoc destination directory] [package name]

C:\projects> javadoc -d C:\javadoc\test com.test

If you want to run javadocs from elsewhere, you'll need to specify the sourcepath. For example, if you were to run javadocs in in C:\, you would modify the command as such:

C:\> javadoc -d [path to javadoc destination directory] -sourcepath [path to package directory] [package name]

C:\> javadoc -d C:\javadoc\test -sourcepath C:\projects com.test

If you want to run javadocs on only selected .java files, then add the source filenames separated by spaces (you can use an asterisk (*) for a wildcard). Make sure to include the path to the files:

C:\> javadoc -d [path to javadoc destination directory] [source filenames]

C:\> javadoc -d C:\javadoc\test C:\projects\com\test\file1.java

Answer 4

For example if I had an application source code structure that looked like this:

• C:\b2b\com\steve\util\
• C:\b2b\com\steve\app\
• C:\b2b\com\steve\gui\

Then I would do:

javadoc -d "C:\docs" -sourcepath "C:\b2b" -subpackages com

And that should create javadocs for source code of the com package, and all subpackages (recursively), found inside the "C:\b2b" directory.

Answer 5

its simple go to the folder where your all java code is saved say E:/javaFolder and then javadoc *.java

example

E:\javaFolder> javadoc *.java

Answer 6

Link to JavaDoc

I believe this will surely help you.

javadoc -d C:/javadoc/test com.mypackage

Answer 7

D:>javadoc *.java

if you want to create dock file of lang package then path should be same where your lang package is currently for example I created a folder name javaapi and unzip src zip file. then use command as bellow

C:\Users\Techsupport1\Desktop\javaapi\java\lang> javadoc *.java
