adding system variable PATH to Info.plist for RCP application on Mac OSX [message #463255]

Context.

The RCP application needs to find the binary "dot" which is located in /usr/local/graphviz-2.12/bin.
The PATH environment variable works in the shell but not from within the RCP. "java.io.IOException: dot not found."

Can I add the path to look into to the info.plist somewhere?

<key>Eclipse</key>
<array>
<string>-startup</string>
<string>../../../startup.jar</string>
<string>-keyring</string>
<string>~/.eclipse_keyring</string>
<string>-consoleLog</string>
<string>-showlocation</string>
</array>

Regards,

Paul

You can do this, but if you open Terminal.app you can then run Eclipse.app/Contents/MacOS/Eclipse and it should inherit the PATH variable from Terminal. However, if you run it from Finder, the environment variable won't be seen, unless you've defined it in the magic environment.plist in your home directory (or wherever it is).

If you want to, you can modify the Info.plist to add the path; there's a list of what you can put in at:

http://developer.apple.com/documentation/Java/Conceptual/Jav aPropVMInfoRef/Articles/JavaSystemProperties.html

http://developer.apple.com/documentation/MacOSX/Conceptual/B PRuntimeConfig/index.html

I don't know what the entry for PATH is in these environments. Of course, modifying the Info.plist is unlikely to help since it would be very specific to that file. You could search for it yourself e.g. look in /usr/local/graphviz* /usr/graphviz* etc. to find it and then execute it. A preference pane could specify where it is if it's not found automatically.

The entries in the info.plist file are processed by eclipse the same as if
they were on the command line. I don't believe Eclipse has any command line
options to modify the path, but your RCP application could check the command
line and do something with it.
