Eclipse Generate Javadoc Wizard what is Javadoc Command

Question

I want to generate the javadocs for an open-source code-base I m using  But I m being asked for a  Javadoc Command  by the Eclipse Generate JavaDoc wizard and the help doesn t explain what this means  Is it wanting the path to the javadoc binary jar or something else

User · Accepted Answer

Yes  presumably it wants the path to the javadoc command line tool that comes with the JDK  in the bin directory  same as java and javac    Eclipse should be able to find it automatically  are you perhaps running it on a JRE  That would explain the request

User · Answer

Yes  it is asking for the application executable that is capable of creating Javadoc  There is a javadoc executable inside the jdk s bin folder

You may need to add a JDK  Java Development Kit  to the installed JRE s within Eclipse  Go to Window- Preferences- Java- Installed JRE s  In the Name column if you do not have a JDK as your default  then you will need to add it   Click the  Add  Button and locate the JDK on your machine  You may find it in this location  C  Program Files Java jdk1 x y Where x and y are numbers   If there are no JDK s installed on your machine then download and install the Java SE  Standard Edition  from the Oracle website   Then do the steps above again   Be sure that it is set as the default JRE to use   Then go back to the Projects- Generate Javadoc    dialog  Now it should work   Good Luck

There are already useful answers to this question above  however there is one more possibility which I don t see being addressed here   We should consider that the java is installed correctly  that s why eclipse could have been launched in the first place   and the JDK is also added correctly to the eclipse  So the issue might be for some reason  e g  migration of eclipse to another OS  the path for javadoc is not right which you can easily check and modify in the javadoc wizard page  Here is detailed instructions    Open the javadoc wizard by Project- gt Generate Javadoc    In the javadoc wizard window make sure the javadoc command path is correct as  illustrated in below screenshot
