Why is a a deprecation warning causing a compile error in SBT

The project I'm working on uses Scala and SBT. I need to introduce the use of a deprecated method in our code and rather than just giving me an error, sbt is giving me a compile error when I try and compile the code.
Is there a flag or setting somewhere that makes this happen that I can change?
method getDB in class Mongo is deprecated: see corresponding Javadoc
for more information.
[error] lazy val db: com.mongodb.DB = mongoClient.getDB("foo")
[error] ^
[error] one error found
[error] (web/compile:compileIncremental) Compilation failed
[error] Total time: 9 s, completed Jun 2, 2017 7:20:53 AM
Thanks.

SBT gives you a lot of options to set depreciation warnings as errors.
set scalacOptions in ThisBuild ++= Seq("-unchecked", "-deprecation", "-Xfatal-warnings")
OR
sbt compile -deprecation
OR
You can configure the same in build.sbt file.
You'll have to remove any of the above options if you are using. (Check your compiler settings)
Also, do sbt clean reload compile.
This worked for me.

Scalac has a flag Xfatal-warnings that turns warnings into errors. See Is there a way in sbt to convert compiler warnings to errors so the build fails? and https://github.com/scala/bug/issues/8410
A workaround is defining a deprecated trait that calls the method and making its companion object implement that trait:
scala> #deprecated("","") def foo = "I am deprecated"
foo: String
scala> #deprecated("","") trait Foo { def safeFoo = foo }; object Foo extends Foo
defined trait Foo
defined object Foo
scala> foo
<console>:13: warning: method foo is deprecated:
foo
^
res0: String = I am deprecated
scala> Foo.safeFoo
res1: String = I am deprecated

In your build.sbt you can set scalaOptions as below :
lazy val exScalacOptions: Seq[String] = Seq(
"-Xlint",
"-feature",
"-deprecation:false",
"-unchecked"
)
After setting the above value you can reference it in your project module settings in build.sbt as below:
scalacOptions := exScalacOptions

GWT: How to use private tag for locale

I'm making an web app using GWT i18n. In this app, I would like to set up a custom property files to support differences from main language. For example I have an en_US locale, but also I would like to have en_US_x_custom support with some redefined property fields (specifications of BCP 47 says that I can use -x tag for private tag support).
Let me show what I have for now:
I have an interface
public interface TestMsg extends Messages {
String value();
}
and few property files:
TestMsg_en_US.properties
TestMsg_en_US_x_custom.properties
In app.gwt.xml, I have this lines
<inherits name="com.google.gwt.i18n.I18N"/>
<inherits name="com.google.gwt.i18n.CldrLocales"/>
<extend-property name="locale" values="en_US"/>
<extend-property name="locale" values="en_US_x_custom"/>
However, the problem is that compilations fails with following messages:
[ERROR] Type com.google.gwt.i18n.client.impl.LocaleInfoImpl_en_US_X-custom could not be referenced because it previously failed to compile with errors:
Tracing compile failure path for type 'com.google.gwt.i18n.client.impl.LocaleInfoImpl_en_US_X-custom'
[ERROR] Errors in 'generated://74EF808C0035420F02374EADB97661B8/com/google/gwt/i18n/client/impl/LocaleInfoImpl_en_US_X-custom.java'
[ERROR] Line 10: Syntax error on token "-", < expected

[ERROR] Line 22: The method getDateTimeFormatInfo() of type LocaleInfoImpl_en_US_X must override or implement a supertype method
[ERROR] Line 10: Syntax error, insert "AdditionalBoundList1" to complete TypeParameter1
[ERROR] Line 27: The method getNumberConstants() of type LocaleInfoImpl_en_US_X must override or implement a supertype method
[ERROR] Line 12: The method getLocaleName() of type LocaleInfoImpl_en_US_X must override or implement a supertype method
[ERROR] Errors in 'com/google/gwt/i18n/client/LocaleInfo.java'
[ERROR] Line 37: Rebind result 'com.google.gwt.i18n.client.impl.LocaleInfoImpl_en_US_X-custom' could not be found
How do I get rid of this compilation error? How can I fix this problem?

You can ommit -x part of the locale. Then you can specify the locale as en_US_custom and have property file named TestMsg_en_US_CUSTOM.properties (notice capital letters).

Can't Run html libgdx with libgdx-utils

Im trying to compile my libgdx game, its working for android and desktop, but not HTML GWT.
Im using Intellij / Gradle for the project.
I just added the libgdx-utils extension lib found here which seems to be causing the error: https://bitbucket.org/dermetfan/libgdx-utils/wiki/Dependency%20Instructions
The error i get when attempting this gradle command ./gradlew html:dist is:

Ive made some progress
In my GdxDefinition.gwt.xml file i needed to add some <inheritis> tags:
<inherits name='libgdx-utils' />
<inherits name='libgdx-utils-box2d' />
That error is now fixed but now i have about 10000 more errors that are similar

And it just goes on and on like this..

GWT needs the source code to compile. Add this to the HTML project in your build script:
compile 'net.dermetfan.libgdx-utils:libgdx-utils:0.7.2:sources'
compile 'net.dermetfan.libgdx-utils:libgdx-utils-box2d:0.7.2:sources'

how to use project/Build.scala generate java playproject?

I use playframework2.2: try to build a play support project.
in my Build.scala, I want to add play.Project.playJavaSetting:
val main = play.Project(appName, appVersion, appDependencies)
.settings(play.Project.playJavaSettings) //error here
.settings(
resolvers += "webjars" at "http://webjars.github.com/m2",
resolvers += "typesafe" at "http://repo.typesafe.com/typesafe/release"
)
the error is:
[error] F:\git\play-example-form\project\Build.scala:19: overloaded method value
settings with alternatives:
[error] (ss: sbt.Def.Setting[_]*)sbt.Project <and>
[error] => Seq[sbt.Def.Setting[_]]
[error] cannot be applied to (Seq[sbt.Setting[_]])
[error] .settings(play.Project.playJavaSettings)
[error] ^
If I do not add playJavaSetting, it give me error about wrong collection apply, I mean:
val main = play.Project(appName, appVersion, appDependencies)
//.settings(play.Project.playJavaSettings)
and the error is:
[error] required: play.api.data.Form<StudentFormData>,scala.collection.immutab
le.Map<String,Object>,scala.collection.immutable.List<String>,scala.collection.i
mmutable.Map<String,Object>,scala.collection.immutable.Map<String,Object>
[error] found: play.data.Form<StudentFormData>,java.util.Map<String,Boolean>,j
ava.util.List<String>,java.util.Map<String,Boolean>,java.util.Map<String,Boolean
you can see the framework apply the scala.collection.immutable.List instead of play.util.List, If I really want to apply the java collections how to set the environment setting in Build.scala file?

You should change
.settings(play.Project.playJavaSettings)
to
.settings(play.Project.playJavaSettings: _*)
The settings method is declared as def settings(ss: Setting[_]*), which means it takes repeated parameters of type Setting[_]. The play.Project.playJavaSettings is of type Seq[Setting[_]]. To convert one to another Scala has a special type annotation.
If you are interested in details check 4.6.2 Repeated Parameters of The Scala Language Specification

google guava with GWT when performing pattern search and range search on collections2

I want to perform search operations on Google Gauva collections in the GWT application.
Those are working correctly in standalone application.But in GWT they are producing
runtime problems.I'm showing my sample code of onModuleLoad() of EntryPoint class.
Iset the buildpath for both guava-gwt-14.0.1.jar and guava-10.0.jar
public void onModuleLoad() {
List<String> sList=new ArrayList<String>();
sList.add("arun kumar");
sList.add("ashok kumar");
sList.add("ravi kumar");
sList.add("kiran kumar");
sList.add("rama");
sList.add("ram");
sList.add("rama krishna");
sList.add("phani");
sList.add("vikram");
sList.add("veeru");
sList.add("arjun");
sList.add("naresh");
//pattern matching
Collection<String> filterdNamesKumar=Collections2.filter(sList, Predicates.containsPattern("kumar"));
//starts with
Collection<String> filterdNamesRam=Collections2.filter(sList, Predicates.containsPattern("^ram"));
Collection<String> filterdNamesAr=Collections2.filter(sList, Predicates.containsPattern("^ar"));
System.out.println(filterdNamesAr.toString());
System.out.println(filterdNamesKumar.toString());
System.out.println(filterdNamesRam.toString());
Map<String,String> emps=new HashMap<String,String>();
emps.put("emp1","01/02/2013");
emps.put("emp2", "10/12/2013");
emps.put("emp3","20/11/2013");
emps.put("emp4", "25/09/2013");
emps.put("emp5", "15/12/2013");
emps.put("emp6", "20/08/2013");
emps.put("emp7", "02/02/2012");
for(String s:emps.keySet()){
String strDate=emps.get(s);
DateTimeFormat dateFormat=DateTimeFormat.getFormat("dd/MM/yyyy");
Date empDate=dateFormat.parse(strDate);
Date startDate=dateFormat.parse("01/11/2013");
Date endDate=dateFormat.parse("31/12/2013");
Range<Date> range=Ranges.closed(startDate, endDate);
boolean b=range.apply(empDate);
if(b){
Window.alert("date found between boundaries");
}
}
}

Patterns.containsPattern is annotated with #GwtIncompatible which means it's not in guava-gwt.
BTW, you should use the same version for guava-gwt and guava.
