Error while starting scala project that uses SORM framework - scala

Question

I have created simple sbt project from tutorial:
build.sbt:
lazy val sorm_test = (project in file(".")).
settings(
name := "SORM_TEST",
scalaVersion := "2.11.7",
libraryDependencies ++= Seq(
"org.sorm-framework" % "sorm" % "0.3.18",
"com.h2database" % "h2" % "1.4.188"
)
)
test.Main.scala:
package test
case class Artist(
names : Map[Locale, Seq[String]],
genres : Set[Genre]
)
case class Genre(
names : Map[Locale, Seq[String]]
)
case class Locale(
code : String
)
import sorm._
object Db extends Instance(
entities = Set(
Entity[Artist](),
Entity[Genre](),
Entity[Locale](unique = Set() + Seq("code"))
),
url = "jdbc:h2:mem:test",
user = "",
password = "",
initMode = InitMode.Create
)
object Main extends App {
// init
Db.##
}
When i run this project in intellij i have such exceptions :
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

It's ok when i use sbt run. This exception is thrown also when i integrate SORM with Play framework. How can i solve this problem ?

Answer 1

I solved this problem by adding dependencyOverrides += "org.scala-lang" % "scala-compiler" % scalaVersion.value to my sbt configuration.

Answer 2

I receive a very similar Exception in a maven project during runtime:
Caused by: java.lang.BootstrapMethodError: java.lang.NoClassDefFoundError: scala/runtime/java8/JFunction0$mcI$sp
I am currently using
<scala.version>2.11.7</scala.version>
<scala.compat.version>2.11</scala.compat.version>
<scalatest.version>2.2.2</scalatest.version>
<scala-maven-plugin.version>3.2.0</scala-maven-plugin.version>
in the pom properties and refer to these properties in all other entries, like
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-library</artifactId>
<version>${scala.version}</version>
</dependency>
Maven packaging/installation works fine. Is this a similar problem? Can someone explain the solution above (or maybe translate it to the maven case)?
