I was trying to run a play sbt multi-project using command 'sbt "project subproject" ~run'
But received following error:
`Expected letter

I think what you want is sbt "~subproject/run"
I had this same problem and, it was because I was running sbt . (with a trailing period).
Just using sbt or sbt [command] solved the problem for me

I want to run this SBT command in Ammonite:
sbt -mem 3000 clean compile docker:publishLocal
I tried a few things like:
%.sbt("-mem 3000", 'clean, 'test)(pwd)
Which gives this exception:
[error] Expected symbol
[error] Not a valid command: -
[error] Expected end of input.
[error] Expected '--'
[error] Expected 'debug'
[error] Expected 'info'
[error] Expected 'warn'
[error] Expected 'error'
[error] Expected 'addPluginSbtFile'
[error] -mem 3000
[error] ^
How is this done?
I recently had to the same thing, and i can tell you that is not fun when those "random" errors happen.
// I had to put the full path where sbt is, like this
val SBT = "C:\\Program Files (x86)\\sbt\\bin\\sbt.bat"
%(SBT, "-mem", "3000", "clean", "compile", "docker:publishLocal")(pwd)
with this the solution is:
%.sbt("-mem", "3000", 'clean, 'test)(pwd)
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.
After adding the following method to map case classes to Map or js.Dictionary - and I've tried now five or six variants of the following - my code compiles fine and without warnings, but then hits errors at the fastOptJS sjs linking stage.
The method
def ccToMap(cc: AnyRef) =
(Map[String, Any]() /: cc.getClass.getDeclaredFields) {
(a, f) =>
f.setAccessible(true)
a + (f.getName -> f.get(cc))
}
Note that all the variants I have tried do the same thing in a slightly different manner.

What I've tried
Being unfamiliar with the details of the linker I am only able to try some "obvious" diagnostics:
Whether I call the method or not, this error is thrown (it doesn't have to be in the code path, so this is getting thrown when the method itself is linked)
The Map type itself works just fine as an argument to the function where I am trying to invoke this
I know to a certainty that iff this method (or similar) is present, then I get the above linker error. (Without, no error.)
Any tips on how to proceed, debug, etc are appreciated.
Alternatively, any tips on how I may convert a case class to a Map without the above-style (reflection-based) function, please let me know
You simply can't use Java reflection in Scala.js:
Java reflection and, a fortiori, Scala reflection, are not supported. There is limited support for java.lang.Class, e.g., obj.getClass.getName will work for any Scala.js object (not for objects that come from JavaScript interop).
Use macros for this instead. See e.g. Scala Macros: Making a Map out of fields of a class in Scala
Currently trying to follow Manning's Play for Scala, specifically the section on testing a module before publishing.
I've created a module named "Ean2BarcodePlayModule" with organization "net.nowhereatall.playforscala".
I've used activator to publish local to ~/.ivy2/local
In my test project, I've added the library dependency:
"net.nowhereatall.playforscala" %% "ean2barcodeplaymodule" % "1.0-SNAPSHOT"
Now, I'd like to modify my routes file to indicate
-> /barcode Ean2BarcodePlayModule.Routes
but this results in:
[error] D:\Tutorials\Workspaces\Scala\Ean2BarcodePlayModule-Test\conf\routes:10:
not found: value Ean2BarcodePlayModule
[error] -> /barcode Ean2BarcodePlayModule.Routes

[error] four errors found

alternatively, if I try:
Now, I'd like to modify my routes file to indicate
-> /barcode net.nowhereatall.playforscala.Ean2BarcodePlayModule.Routes
the result is:
[error] D:\Tutorials\Workspaces\Scala\Ean2BarcodePlayModule-Test\conf\routes:10:

What is the correct way to do this?
With thanks to #Sarvesh Kumar Singh for directing me to the page on "SubProjects", the solution was relatively simple.
Rename "routes" in the the module source to "barcode.routes".
Redo activator publish-local.
In the "Test" project route file, include the required line as
-> /barcode barcode.Routes
(Note the last "R" in "Routes" is capital. That seems to be important!)

I found this post about this issue pointing out to be a library mismatch but I'm using jars from the Vaadin SCM for the correct release: https://vaadin.com/forum/-/message_boards/view_message/384826
Issue finally fixed, hopefully that does the trick. After that had to add the following jars to the project so it could be compiled:
validation-api-1.0.0.GA.jar
validation-api-1.0.0.GA-sources.jar
