Scala Sbt error - scala

I'm trying to run JAMR which needs Scala and SBT...
However I ran into this problem when I tried to get sbt to work:
I have Scala installed and working:
This is what I get when I run Scala
reza#reza-ubi:~$ scala
Welcome to Scala 2.12.2 (Java HotSpot(TM) 64-Bit Server VM, Java
1.8.0_131).
Type in expressions for evaluation. Or try :help.
scala>
I downloaded the deb file and followed the quite simple instructions on the sbt page but
and when I run sbt:
reza#reza-ubi:~$ sbt
Getting org.scala-sbt sbt 0.13.15 (this may take some time)...

How do I get it to work?

How to extract a standalone FPU module from Rocket-Chip Chisel code?

I am working on Rocket Chip Generator, which is a SoC written in Chisel.
My objective is to extract the Floating-Point Unit, in order to synthesize it and study its power consumption/area ...etc. separately from the rest of the SoC.
So I cloned the project and tried to create a dedicated TestHarness where I only instanciate an FPU. This is an example code of what I did (very similar to TestHarness
package freechips.rocketchip.system
import Chisel._
import freechips.rocketchip.config.Parameters
import freechips.rocketchip.devices.debug.Debug
import freechips.rocketchip.diplomacy.LazyModule
import freechips.rocketchip.rocket._
// importing FPU class
import freechips.rocketchip.tile._
class FPUTestHarness() (implicit p: Parameters) extends Module {
val io = new Bundle {
val dummyIn = Bool(INPUT)
val dummyOut = Bool(OUTPUT)
}
// The parameters of the FPU
val fpu_params = FPUParams(
fLen = 32 // default is 64
divSqrt = false // default is true
// sfmaLatency = 3, // default
// dfmaLatency = 4 // default
)
val fpu = Module(new FPU(fpu_params)(p))
}
The problem is that the implicit parameter p (of type Parameters) doesn't contain something called TileKey, which is needed I don't know where. Apparently the implicit parameter p, passed to FPUTestHarness doesn't contain that information. How can I resolve that? Is it possible to hardcode that somewhere for example?

It seems that you use the config as "DefaultConfig". Error log states that you did not specify TileKey parameter in this config. Adding TileKey parameter will resolve the issue. DefaultConfig is defined in rocket-chip/src/main/scala/system/Configs.scala

What is the maximum number of case class fields in scala?

It used to be 22, I heard someone say it's now 512? Is that correct? Can someone provide a source.

In Scala 2.11 there is an implicit limit, it seems if you create a case class with about more than 100 fields you get a stack overflow (see bottom of answer).
A workaround to get the number of fields higher (up to 254) is
export SBT_OPTS="-XX:MaxPermSize=2G -Xmx2G -Xms2G -Xss8M"
If you try any higher than 254 you get
[error] /Users/sams/src/.../src/main/scala/com/MegaClass.scala:6:12: Platform restriction: a parameter list's length cannot exceed 254.

It's 22 if you want json (de)serialisation. At least in pre Scala 3. It might have changed in Scala 3.

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0
i am not sure whether it's emacs config issue or sbt config issue , i am newer for scala and emacs, very appreciate for any help, it block me lots of time

found a solution from emacs-sbt-mode
https://github.com/ensime/emacs-sbt-mode/issues/120
(setq sbt:program-options '())
Works for me on:
OS: Windows 10 x64 edition
SBT: 1.2.8
JDK: 1.8.0_211
Emacs: 26.2.90 (build 2, x86_64-w64-mingw32) of 2019-06-14
sbt-mode: 2.0.0
scala-mode: 1.0.0
ensime: 2.0.2

troubleshooting jar loading conflicts in sbt

I get the following error on sbt startup, when two specific sbt plugins are added together to a project in its build definition. One of these sbt plugins is scalikejdbc and the other is my own, and clearly their mutual inclusion in a project's build definition results in this error upon sbt startup:
scala.reflect.internal.Types$TypeError: package macros contains object
and package with same name: blackbox
Clearly, it looks as if each plugin brings along a different version of scala.reflect.macros thus causing this error. I can poke inside the jars of the sbt plugins, and indeed one of them may seem to bring along a scala/reflect/macros/blackbox.class ―
$ jar -tvf scalikejdbc-core_2.10/jars/scalikejdbc-core_2.10-2.4.2.jar | grep black
0 Sat Jun 11 15:51:10 IDT 2016 scala/reflect/macros/blackbox/
405 Sat Jun 11 15:51:04 IDT 2016 scala/reflect/macros/blackbox/package$.class
419 Sat Jun 11 15:51:04 IDT 2016 scala/reflect/macros/blackbox/package.class
― however it's hard to positively conclude what gets loaded by sbt during this early startup phase, in order to figure which versions of this package are involved here and which dependencies bring them along.
Thanks for your suggestions about how to proceed with this investigation!
And just for completeness sake ― I include below the full error given by sbt below only ― but I sincerely doubt it adds any information so you can likely ignore it.

one of them needs to be removed from classpath

Copying #jrudolph's comment here:
FWIW giving some advice to someone coming to this issue later on also having problems with plugin classpaths. Try adding scalacOptions ++= Seq("-verbose", "-Ylog-classpath") to project/plugins.sbt. This will print out detailed information when the scala compiler loads classes when compiling the build. This should give a hint from which the jar the conflicting classes came from.

Play framework, 2.x clean project, test fails - MAC OS

I think this should be due to some issues in my enviroment, I can't figure this out so I am posting a question.
I created a new play 2.1.3 project (scala 2.10.2).
When I run play for the first time (no file is edited at this stage) and run the test sbt command, I get the following error.

UPDATE - Problem Fixed
These files somehow managed to get into classpath,
rm /Library/Java/Extensions/log4j-1.2.15.jar
rm /Library/Java/Extensions/slf4j-api-1.5.8.jar
rm /Library/Java/Extentions/slf4j-log4j12-1.5.8.jar
I don't know which program placed these files.

Play logger will be called by default even if you don't use it. Check your application.conf
it contains something like:
# Root logger:
logger=ERROR
# Logger used by the framework:
logger.play=INFO
# Logger provided to your application:
logger.application=DEBUG
and Play.logger uses log4j and slf4j both as you can see above . So you need to configure them properly .
Check this question for setting up slf4 and log4j How to get SLF4J "Hello World" working with log4j?
