Subject: Mismatch between compiler results of 2.10-RC1 Scala IDE and Scala compiler
Print | Individual message | Show original | Report this message | Find messages by this author

I'm experiencing differences regarding compiler errors when compiling the
same code base with

Scala 2.10.0-RC1 / SBT
and
Scala IDE 2.1.0 Milestone 2 for Eclipse 3.7 for Scala 2.10.0-RC1
(http://download.scala-ide.org/releases-210/milestone/org.scala-ide.sd...)

What am I missing?

What are the differences?

Hi Iulian,

while the code base compiles fine in the Scala IDE, compiling it via SBT I
get

[error] not enough arguments for method 'findEntry': ...
[error] Unspecified value parameter 'correspond'

How could the cause of the distinct behavior detected? Do you need to
reproduce it or can I check some internals before?

It unexpected. Is `findEntry` a method that has default parameters? A
reproducible test case would for sure help!

Iulian:

There are two overloaded versions of findEntry. The first is defined in
scala.collection.mutable.FlatHashTable, the other in
scalax.collection.mutable.ExtHashSet. Default parameters are not involved.

> A reproducible test case would for sure help!

Please find the code base mentioned at
http://subversion.assembla.com/svn/scala-graph/trunk

For compiling with the Scala IDE, you just need to place a project at
Core/src without any library dependencies.
For compiling with SBT 0.12.1, first refer to project/readMe.txt and then
execute on the SBT console

> project Graph-core
> compile

You'll find 11 significant [error] lines while warnings should be ignored
all together.

Thanks, Peter

Sorry, I forgot to mention that, preparing SBT compile, you also need to
set scala_2_9 to false in Version.scala.

I can now tell the specific reason for the error reported by the SBT
compilation:
https://groups.google.com/forum/?fromgroups=#!topic/scala-internals/m....

But I still cannot explain the difference between Scala IDE, not detecting
any error, and Scala.

Maybe a mismatch between the Scala library version used in your Sbt build definition and the one in the IDE (i.e., Scala 2.10.0-RC1).

or in SBT. Do I have to? I'm just setting the compiler version.
In SBT, scala-version == scala-binary-version == 2.10.0-RC1

SBT also reports:
[warn] Binary version (2.10) for dependency
org.scala-lang#scala-library;2.10.0-RC1
[warn]  in com.assembla.scala-incubator#graph-core_2.10.0-RC1;1.5.2 differs
from Scala binary version in project (2.10.0
-RC1).

Mirco, just the other way round: I have a bad reference to the 2.10.0-M7
Scala Library in Eclipse!

In Sbt, by setting the scala-version, you are effectively setting both the Scala library and compiler version. In Eclipse, the answer depends
on how you configured your project's classpath: make sure you only have one scala-library.jar, and that its version is indeed 2.10.0-RC1.

Great! Then, you did not really update to the latest M2 for Scala 2.10.0-RC1 ;-)

Eclipse Installation Details:
Scala IDE for Eclipse    2.1.0.m2-2_10-201209130850-f6ab297

Plugin from:
http://scala-ide.org/download/milestone.html#scala_ide_21_milestone_2
via zip
http://download.scala-ide.org/releases-210/milestone/org.scala-ide.sd...
titled "For Scala 2.10.0-RC1"

Is that not correct for RC1?

The moment Scala 2.10.0-RC1 we have released an updated M2 bundled with Scala 2.10.0-RC1.

However, the zip file http://download.scala-ide.org/releases-210/milestone/org.scala-ide.sd...
was NOT updated. That's why you are getting the old Scala library, it's our mistake.

Please, file a ticket on our issue tracker (https://scala-ide-portfolio.assembla.com/spaces/scala-ide/support/tic...)
and, use the following update site to get the Scala IDE M2 with Scala 2.10.0-RC1:

        http://download.scala-ide.org/sdk/e37/scala210/dev/site/

Sorry for the trouble that this caused.
