[Doxygen-users] doxywizard can't run PlantUML

[Michael S. P. <msp...@ra...>]

I am trying to use the doxywizard with PlantUML.  PlantUML works fine by itself.  But when the doxywizard gets to the step to invoke PlantUML, it throws up a dialog saying "choose the program you want to use to open this file: java.exe".  Why is it trying to "open" java.exe?  It should just run it!  I'm on Windows 7 Professional, 64-bit.  Doxygen is 1.8.9.1 installed from the binary distribution doxygen-1.8.9.1-setup.exe.

Any help is appreciated!

I found a work-around for this exact problem by side-stepping the "java.exe"
shortcut that is installed by the java installer (java version "1.8.0_45")
at "C:\ProgramData\Oracle\Java\javapath".  Look at your "Path" environment
variable in a command prompt window (type "path") and see if the directory
for java includes symlink entries as it does on my system (Win7 64 bit).  If
you look at "properties" for the shortcut called "java.exe" you can see
where it points to the real executable:

C:\ProgramData\Oracle\Java\javapath>dir
 Directory of C:\ProgramData\Oracle\Java\javapath
...
07/01/2015  09:01 AM    <SYMLINK>      java.exe [C:\Program Files
(x86)\Java\jre1.8.0_45\bin\java.exe]

So, I wrote a short batch file to prepend the actual install directory of
java to the front of my path that I can run before running doxygen (in the
same Command Prompt window):

REM Put the "real" java path in front of the one with a symlink to work with
doxygen:
set Path=C:\Program Files (x86)\Java\jre1.8.0_45\bin;%Path%

Now Plantuml diagrams are created fine via doxygen.

I would NOT recommend modifying your "Path" environment variable permanently
because this could open various security holes or break other things.

Hopefully someone will figure out the underlying problem with how java is
launched from doxygen and make plantuml work out-of-the-box.

That's becoming a pain though as soon as the JRE is updated.

I had this issue, too; it appears that, as of recently, Windows refuses 
to execute symbolic links with an ".exe" extension. On the interwebs 
there are some hints that this change in behaviour was introduced with 
security update KB3039066 (see 
https://support.microsoft.com/en-us/kb/3039066), and indeed selectively 
uninstalling that update fixed the problem for me. (Obviously you'll 
have to live with an unpatched potential security issue instead, so you 
may choose not to go that way.)

Yes - I see the problem has wider scope than I thought; I tried other
symlinks (created with mklink.exe from command prompt) and indeed I cannot
execute programs through these symlinks via explorer but can use them
successfully from command prompt.

I'm not a Java developer (C++) so I don't know what the scope of this
problem is (how many programs are affected given that there are other ways
to run java), but I found a link about this problem on an Oracle discussion
thread from April 1, 2015, so the problem has been around for at least three
months:

https://community.oracle.com/thread/3695801
<https://community.oracle.com/thread/3695801>  

As of now, I'm launching doxygen from Visual Studio in an nmake project and
I'm patching the path there (as above) - this will have to suffice until
Oracle fixes the problem or offers a safe alternative.

In the batch file I'm using to run Doxygen, I've now added the following
subroutine to get around the problem:

------------------------------

------------------------------

If you need to use doxywizard to actually run Doxygen (as opposed to just
generating a config file for it), you could launch doxywizard via a batch
file, using the very same code snippet; as far as I know that should do the
job as well.

Sorry the code got truncated; I should probably have posted directly to
the list.
Here's the code again:

------------------------------------------------

:JAVA_SYMLINK_FIX

rem set JAVA_EXE to whatever java.exe is found via the path
call :FIND_IN_PATH JAVA_EXE java.exe
rem set TRUE_JAVA_EXE to the actual file java.exe points to (if it is a
rem symlink), or an empty string otherwise
call :FIND_SYMLINK TRUE_JAVA_EXE "%JAVA_EXE%"
rem if the java.exe found via the path is not a symlink, we're done
if "%TRUE_JAVA_EXE%" == "" goto :EOF
echo "%JAVA_EXE%" is a symlink pointing to "%TRUE_JAVA_EXE%"
rem set JAVA_EXE_DIR to the directory in which the actual java.exe resides
call :SET_DIR JAVA_EXE_DIR "%TRUE_JAVA_EXE%"
rem prepend JAVA_EXE_DIR to the path variable
set PATH=%JAVA_EXE_DIR%;%PATH%
 goto :EOF

:FIND_IN_PATH
set %1=%~dp$PATH:2%2
goto :EOF

:FIND_SYMLINK
rem Sets the environment variable named by %1 to the file pointed to by %2
rem if that's a symlink.Sets the environment variable to an empty string
rem otherwise.
set %1=
for /F "usebackq tokens=2 delims=[]" %%i in (`dir "%~2" /N`) do set %1=%%i
goto :EOF

:SET_DIR
rem Sets the environment variable named by %1 to the directory of the file
rem named by %2.
set %1=%~dp2
goto :EOF
