How to generate Javadoc from command line

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 

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 

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 

More information/scenarios can be found here.

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.

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

The answers given were not totally complete if multiple sourcepath and subpackages have to be processed.

The following command line will process all the packages under com and LOR (lord of the rings) located into /home/rudy/IdeaProjects/demo/src/main/java and /home/rudy/IdeaProjects/demo/src/test/java/

Please note:

• it is Linux and the paths and packages are separated by ':'
• that I made usage of private and wanted all the classes and members to be documented

rudy@rudy-ThinkPad-T590:~$ javadoc -d /home/rudy/IdeaProjects/demo_doc -sourcepath /home/rudy/IdeaProjects/demo/src/main/java/ :/home/rudy/IdeaProjects/demo/src/test/java/ -subpackages com:LOR -private rudy@rudy-ThinkPad-T590:~/IdeaProjects/demo/src/main/java$ ls -R .: com LOR ./com: example ./com/example: demo ./com/example/demo: DemowApplication.java ./LOR: Race.java TolkienCharacter.java rudy@rudy-ThinkPad-T590:~/IdeaProjects/demo/src/test/java$ ls -R .: com ./com: example ./com/example: demo ./com/example/demo: AssertJTest.java DemowApplicationTests.java 

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 unzipped the src zip file, then used the command below.

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

I believe this will surely help you.

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