I'm following the provided instructions but is not working. I'm getting this error:

I found a related bug but it's been reported for a long time without fix yet. Any ideas besides checking/modifying the code myself?
Edit: Looking closer at the output I noticed this errors:

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

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

It's 22 if you want json (de)serialisation. At least in pre Scala 3. It might have changed in Scala 3.
I was trying to run a play sbt multi-project using command 'sbt "project subproject" ~run'
But received following error:

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
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:

alternatively, if I try:

the result is:

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 am new to Java and GWT.
I want to make use of dom4j and jaxen to parse a xml file and construct the webpage according
to the xml file content.
However, the compile fail and the error is listed below:
[ERROR] [MainPage] - Errors in 'file:/E:/workspace/MainPage/src/com/helloworld/client/MainPage.java'
[ERROR] [MainPage] - Line 10: The import org.dom4j cannot be resolved
[ERROR] [MainPage] - Line 81: The type org.dom4j.DocumentException cannot be resolved. It is indirectly referenced from required .class files
[ERROR] [MainPage] - Line 81: The constructor DataModelReader(File, SmfDataPositionAgent) refers to the missing type DocumentException

[ERROR] [MainPage] - Line 87: The method navigatePageSet() from the type DataModelReader refers to the missing type DocumentException
[ERROR] [MainPage] - Line 88: DocumentException cannot be resolved to a type
I don't think it is possible to use dom4j on client side as it is not a GWT module. Maybe you should consider using GWTs XML parser:
http://www.gwtproject.org/doc/latest/DevGuideCodingBasicsXML.html
Or you can try with this project, I haven't try it though.
