Hi,

I am trying to get the GraphViz representation for my Hibernate mappings work with HibernateTools-3.2.0.beta9a on Mac OS X.

Inside the hibernate.cfg.xml I located (dot is accessible from the bash shell just fine):

<property name="dot.executable">/usr/local/bin/dot</property>

This is how I added the schema documentation in my ant task:

<hibernatetool destdir="hibernate-html">
<configuration configurationfile="hibernate.cfg.xml" />
<hbm2doc/>
</hibernatetool>

The result is:

[hibernatetool] An exception occurred while running exporter #2:hbm2doc (Generates html schema documentation)
[hibernatetool] To get the full stack trace run ant with -verbose
[hibernatetool] org.hibernate.HibernateException: Problem while generating DOT graph for Configuration
[hibernatetool] java.io.IOException: "/usr/local/bin/dot": not found

From what I saw in the sources (DocExporter#dotToFile) it seems the dot command is escaped on Mac OS X, but the quotes will not work. To fake a Linux system (where the escape not happens), I specified ANT_OPTS=-Dos.name=Linux which is a bit tricky but seems to work.

Any chances to fix this issue in the next tools release?

Thanks for the nice GraphViz integration anyway,
Niko

put in jira and best of all submit a patch and test it since I don't have an easy way to test on mac.

Was there any resolution to this issue? I am seeing the same issue using hibernate3-maven-plugin on Mac OSX 10.5.5.

Thanks,
Brendan

Running like this seems to work:

mvn -Dos.name=Linux install

similar to ant approach. Is this going to get fixed?

Thanks,
Brendan

i dont recall any jira or patch for it yet .... feel free to help out!
