Hi,

there seems to be a problem in the ShellBolt that I would like to figure out. If you use Storm multilanguage features and you try to communicate with a C++ using something like StormCpp it will possibly fail as long as you embed the resource direclty (Also see nathanmarz/storm#229). But if you just have a simple running executable that is placed in a PATH folder (like /usr/local/bin on Linux) it will fail with "Caused by: java.io.IOException: Cannot run program "xy"". The problem seems to be the ShellProcess - class where it does something like setting the directory to the codeBaseDir which is set to the resource - folder. As long as you have not assigned a resource - folder in your maven file it will always fail. Something like:

<build>
<resources>
<resource>
<directory>${basedir}/SomeDirectory</directory>
</resource>
</resources>
</build>

will fix it but it's only a workaround. I can also provide you with a simple code-example if needed. A possible solution would be that the ShellProcess should check if the codeBaseDir exists so that I cannot fail.
