Re: Crash in the build compiler -- error message is null

[Lavino]

I attend my code here:

https://www.dropbox.com/sh/dp6hu5el96ofv6d/YJaFRKGXIa/Akka_scala_subpub

and the redis client that I used is redisclient_2.9.1-2.4.0.jar which is include in akka-2.0.2 ( download from akka.io website)

Hi,

You came across this issue with a "lucky" timing, as I've seen the same on one of our projects this 

morning :)

The reason in our case was a missing JAR in the Eclipse build path, the compiler spits out a pretty 

tremendous error as you have experienced. Below is the ticket related to the issue

https://scala-ide-portfolio.assembla.com/spaces/scala-ide/tickets/1001220

I'm pretty confident you are hitting the same issue.

We need to check it we can fix this in the Scala IDE, but most likely this is something that should be fixed 

in the Scala compiler itself.

One more thing, if you are using a nightly for the Scala IDE V2.1, set the logging level to DEBUG [1], do a 

full clean/build in the project, open the log and you should be able to identify what classfile the compiler 

is not able to find (the error should be something on the line: no symbol for XXX needed by YYY).

Hope this helps.

Hi, I try to run a scala project for akka & redid pub/sub in eclipse , but when I finished my code, I got this error message in Markers:

The SBT builder crashed while compiling your project. This is a bug in the Scala compiler or SBT. Check the Erorr Log for details. The error message is: null
