doing javadoc with ant in eclipse

[Jason Hocker]

I have a build.xml that wants to do javadoc, but get the error...


Cannot run program "javadoc.exe": CreateProcess error=2, The system cannot find the file specified


How do I set the path?

[Pavan Kumar]

Create Process Error=2 normally occurs when you don't have the specified process in path.

This is one way of doing it in ant (haven't tested this)
if you have a JAVA_HOME variable set, you could refer to the javadoc.exe as follows.

 <property environment="env"/>
<exec executable="${env.JAVA_HOME}/bin/javadoc" output="${javadoc.dir}">
<arg line=""/>
</exec>
 
   

There may be other elegant ways. for instance the javadoc task in ant may be a better choice than exec. Or may be you could add JAVA_HOME/bin to your path.

I planned to use the javadoc method. I am new to ant, so I appreciate any help.

Can you show us the relevant part(s) of your ant script, please?

[Jason Hocker]

<target name="javadoc" depends="compile">
<javadoc sourcepath="${source}" destdir="${javadocs}" packagenames="*" />
</target>

We have a separate forum for Ant, so I'm moving your post there since it has more to do with Ant than Eclipse.

Does the JAVA_HOME environment variable point to a correct JDK root folder?

[Carol Enderlin]

If you run with -verbose argument you should see what path it is trying to use for javadoc.exe.

Here's mine:

 
 [javadoc] Executing 'C:\mypath\jdk142_05\bin\javadoc.exe' with arguments:
...

I am having the same problem on my home PC. The strange thing is, it works fine on my computer at work, and they are similarly configured. My JAVA_HOME and ANT_HOME are set correctly.

Why can't Ant find the javadoc executable for the <javadoc> task, the same way it finds the javac executable for the <javac> task?

I just updated my Eclipse to the very latest updates (2009-03-26). I googled this today and found no help either.

Thanks

Hi Geoffrey,

We try not to URL=http://faq.javaranch.com/java/DontWakeTheZombies]WakeTheZombies[/URL] around here . Can you post your specific problem in a separate thread? I'd post your full PATH and JAVA_HOME details in the new thread and we can get started!
