CreateProcess error=206, The filename or extension is too long when trying to run ScalaTest in ScalaIDE on Windows 7 64bit

[Tong Chen]

I got the following error when trying to run ScalaTest from Eclipse using "Runas -> ScalaTest - File" from context menu

Exception occurred executing command line.

Cannot run program ""[PATH to javaw.exe]"" (in directory "[path to the project]"): CreateProcess error=206, The filename or extension is too long

Launching the very same test using "Runas -> Scala Junit Test" is fine.

Here are the details of my envionrment:

Eclipse 20130919-0819

Scala IDE for Eclipse 3.0.2.v-2_10-201310181157-0880865

Sorry if the above information not enough for investigation as I am not quite sure how to dig a bit deeper to get more information such as logs. 

I guess the question I want to ask are 

1. What are the differences between running scalatest using "ScalaTest - File" and "Scala Junit Test"

2. How can I see the command line it (ScalaTest - File) uses to run the tests?

Many Thanks,

Tong

Some additional info.

For the same project and same test cases in the same IDE, I can run them perfectly on Mac. But failed to run on both parallel VM windows 7 64bit and native windows 7 64bit.

Hi Tong, 

Sorry for replying late, was busy getting the ScalaTest plugin to work for scala-ide 4.0.0-M1 milestone today.  The problem sounds like a windows path limitation problem.  A quick google result seems that ScalaTest plugin is not alone: 

http://stackoverflow.com/questions/10519558/createprocess-error-206-the-filename-or-extension-is-too-long-when-running-main

https://bugs.eclipse.org/bugs/show_bug.cgi?id=327193 

They suggested workaround like -cp to a generated classpath, which I'll try to investigate.  For your info, here's the source code responsible for launching: 

https://github.com/scalatest/scalatest-eclipse-plugin/blob/master/org.scala-ide.sdt.scalatest/src/scala/tools/eclipse/scalatest/launching/ScalaTestLaunchDelegate.scala 

It is interesting to know that "Scala Junit Test" one works though, I can try to study the related source code (probably early next week) to see if there's a solution, and since I don't have access to a window system it will be great if you can help to verify if there's a solution later. :)

Cheers, 

Chee Seng

Thanks Chee Seng, this community forum for developer support is certainly one of the most responsive ones I have ever used. I am really impressed that many actual committers are helping us here.

Hi Tong, 

I studied the source code of JUnit plugin and the ticket on eclipse itself: 

https://bugs.eclipse.org/bugs/show_bug.cgi?id=327193 

Though it is already marked as resolved/closed, Jimisola Laursen reported at the end of the list that he still encounter that in the latest kepler sr1 with the same build id that you reported.  I managed to workout a solution and build a new version, but it could take sometime for scala-ide guys to pull it (if they didn't, there's a scheduled task that runs once a day to pull new build), when the update is available later can you try to see if it fix your problem?

Cheers, 

Chee Seng

Great, thanks Chee Seng, I will give it a go and update here. 

Best Wishes,

Hi Chee Seng,

Your fix worked. I used the one from http://download.scala-ide.org/sdk/e38/scala210/dev/site/plugins/ and tried on both Selenium and Unit Scala tests. They both working fine. :)

Thanks a lot for the super quick fix.

Best Wishes,
Tong
