An internal build error has occurred – Flex

While debugging on my current project, my flex builder got crashed with out any known reason.

And when I restart my Flex builder I got this error.

An internal build error has occurred. Right-click for more information.

Well just to start with…

• No information provided at all on right clicking.

• You don’t get jumped on the location. Strange but don’t know why?
• Shows error at line -1.  Where to find this line?

After googling for a while I encounter that many of the Flex developer has faced this similar error. Have a look what  9Media has to say for the same. They have compile some of the most interesting set of reason found for this error.

I was more interested in the  2nd point which talks about “adl.exe” process. I couldn’t locate the specified process.

After, trying hare I restarted my system. Well, yes it solved my problem too.

So, my conclusion is that there might be any other process which still running (considering my last action i.e. debugging the application).

I also tried the empty “switch“  case. And yes, it is one of the reason for this error. I guess Flex builder throws a general error for all these unknown and strange reasons.

Hope Adobe came up with little bit more creative and informative error messages in next build.
