mac-osx fresh install worksheet wont evaluate anything #85

Closed programatt closed 11 years ago

programatt commented 12 years ago

Steps to reproduce.

  1. Create new project
  2. Add worksheet to project
  3. Notice that initial contents do not evaluate (nothing on right hand side of sheet)
  4. Add another line without syntax errors and save.
  5. Notice neither line is evaluated

I have also checked under Preferences -> Scala Worksheet and saw that the checkbox for Evaluate worksheet on save is checked and greyed out so it is not able to be unchecked.

This is a fresh install of whatever version is available at http://typesafe.com/technology/scala-ide

This was fixed by adding -Dcom.ibm.icu.util.TimeZone.DefaultTimeZoneType=ICU to the config.ini file and restarting. I have absolutely no idea why, because it was in a forum post. But obviously is a bug.

dragos commented 12 years ago

Matt, thanks for your bug report and fix. I am puzzled: the steps you give are not enough to reproduce it. In fact, Mac OS X is the most tested platform, given that the worksheet was developed on Macs. I can definitely not reproduce it with either the Scala IDE or the Typesafe IDE. It must be something else, but I will investigate and try to understand where does the timezone come into play. Could you post the link to the forum?

I have the same problem on Linux. Downloaded scala-ide just today:

Scala plugin version: 2.1.0.m2-2_09-201209130821-0dd7542 Scala compiler version: 2.9.3.v20120906-004703-4c11a6593c Scala library version: 2.9.3.v20120906-004703-4c11a6593c Eclipse version: 3.7.2.v201202080800

But -Dcom.ibm.icu.util.TimeZone.DefaultTimeZoneType=ICU did not help me, so may be it is not really the 'same' problem.

Heh.

java.lang.NumberFormatException: For input string: "Picked"

I realized that I have _JAVA_OPTIONS environment variable defined, so when every Java program is started it first output: Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel

And if I unset _JAVA_OPTIONS before starting eclipse the problem is gone.

programatt commented 12 years ago

@dragos unfortunately I think the forum post is not publicly available because it's in a coursera class. I don't even have the original forum post because many of the students (Odersky's scala programming class on coursera) had this issue, and the one post I found with this answer in it just said "I'm not sure where I found the answer but adding (that line) fixed it". I do know that I didn't have the scala ide or any eclipse installed before I did this. All i did was download the scala ide from the typesafe website and run it. To be quite honest I don't know how to tell if that was in fact what fixed it, because I added the line to the config file, then rebooted, and it worked. If the ide threw an exception or something maybe I could have debugged it. I'd be willing to help you troubleshoot it if you can tell me how I can get a meaningful message about why it doesn't evaluate the worksheet. Maybe if I remove that line and reboot eclipse and try and evaluate a worksheet will it log somewhere that I can send you?

dragos commented 12 years ago

@mathewrphillips Thanks a lot for your help. @Bad-ptr has some diagnostics and a very precise indication of what needs to be fixed. It may be the same problem, you could check the scala-ide log file (Eclipse Preferences/Scala/Logging and there's logging leve, as well as a link to open the log file) and see if you see the same NumberFormatException being logged.

yackx commented 11 years ago

Ran into the same problem with a recent build:

Build id: 3.0.0-vfinal-20130326-1146-Typesafe

Simply removed the worksheet body, put a single println that got evaluated, then paste my actual worksheet.

lischenko commented 11 years ago

Same symptoms, different stack trace, -Dcom.ibm.icu.util.TimeZone.DefaultTimeZoneType=ICU does not help.

Problems occurred when invoking code from plug-in: "org.eclipse.text".

I had the same issue when installing from the marketplace. By switching the default jre to java 6 the worksheet is working again. Ubuntu 13.04 64bit.
