Worksheet does not evaluate when the project name has a SPACE. (OS X)

[sakoht]

I just installed the latest Scala IDE on a fairly new Mac, and the worksheets do not evaluate. No error messages.

To reproduce from scratch:

1. On a Macbook Air running up-to-date OS X Yosemite 10.10.4.
2. Download the latest stable Scala IDE: http://downloads.typesafe.com/scalaide-pack/4.1.0-vfinal-luna-211-20150704/scala-SDK-4.1.0-vfinal-2.11-macosx.cocoa.x86_64.zip
3. Launch directly from the download directly by double-clicking eclipse.app.
4. Select "New" > "Scala Project".
5. Enter "Hello World" and press enter.
6. Right-click on the project and choose "New" > "Scala Worksheet"
7. Give it a name like "Sheet".
8. Note that the single line of example code doesn't evaluate:

Environment:

• sbt launcher version 0.13.7
• comand-line tools 6.4 (July 4, 2015)
• java version "1.8.0_25"

Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

I ran from a terminal and did not see any error messages.

Is there anything shown in the error log (Scala > Show Log)?

[sakoht]

Nothing that says anything about an error.

I did a fresh restart with an empty log file, and went straight viewing the sheet. This is the log content:

I made a one-character change and re-saved. Still no errors in the log.

[kiritsuku]

The error log view (Window > Show View > Other > Error Log) doesn't show anything either? I just tested in with the Linux 64bit version and everything works fine there. Don't have a Mac to test it there though.

[sakoht]

The only new entry is an info message:

System property http.nonProxyHosts has been set to local|*.local|169.254/16|*.169.254/16 by an external source. This value will be overwritten using the values from the preferences

[sakoht]

The error occurs only when the project name has space????

These were made identically, except for the project names:

[kiritsuku]

Thanks, that is it. When I enable debug logging I get:

2015-07-16 16:50:51,284 DEBUG [bundle-320-ActorSystem-akka.actor.default-dispatcher-4] - System.out - [WARN] [07/16/2015 16:50:51.284] [bundle-320-ActorSystem-akka.actor.default-dispatcher-2] [akka://bundle-320-ActorSystem/user/worksheet-runtime/worksheet-manager] Illegal actor name [worksheet-runner-for-project-Hello World]. Actor paths MUST: not start with `$`, include only ASCII letters and can only contain these special characters: -_.*$+:@&=,!~';.

[sakoht]

Where did you enable the logging to see that?

[kiritsuku]

Window > Preferences > Scala > Logging > Log Level: Debug

[sakoht]

I see. And was a DEBUG message instead of an ERROR.
