java.lang.NoClassDefFoundError while compile simple program scala - scala

I have a issue with my really simple project in Scala:
Error:scalac: Error: Could not initialize class com.sun.jna.platform.win32.WinBase$FILETIME

Here you can find code:
object Task1 {
def main(args: Array[String]) {
val dayOfWeeks = List("Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday")
for (e <- dayOfWeeks) println(e + ";")
}
}
Do you have any idea? I tried to uninstall the plugin and rebuild the project but nothing. I installed plugin property and will try with first project in Scala but I faced this error code.

I found the solution after many trials and errors. You need to run the development environment (in my case Intellij) as an administrator. After that you need to re-create or rebuild the project and everything should be fine.

Azure Databricks, could not initialize class org.apache.spark.eventhubs.EventHubsConf

I'm pretty new to Scala and I'm trying to create a notebook to elaborate data written in an Azure Event Hub. This is my code:
import org.apache.spark.eventhubs._
val connectionString = ConnectionStringBuilder("MY-CONNECTION-STRING")
.setEventHubName("EVENT-HUB-NAME")
.build
val eventHubsConf = EventHubsConf(connectionString)
.setStartingPosition(EventPosition.fromEndOfStream)
val eventhubs = spark.readStream
.format("eventhubs")
.options(eventHubsConf.toMap)
.load()
And I get the following error: java.lang.NoClassDefFoundError: Could not initialize class org.apache.spark.eventhubs.EventHubsConf$
Cluster Configuration:
Databricks Runtime Version: 7.0 (includes Apache Spark 3.0.0, Scala 2.12)
Driver & Worker Type: 14.0 GB Memory, 4 Cores, 0.75 DBU
Standard_DS3_v2
I have installed the following library:
com.microsoft.azure:azure-eventhubs-spark_2.11:2.3.17
cluster libraries
The other JAR installed is to resolve a problem with Logging
The code crashes as soon as I try to create eventHubsConf.
Complete traceback:

It seems that your Runtime includes Scala 2.12 but your package is from scala 2.11

Here is piece of code runnig in sbt, but failing in Intellij:
class ReportsDemographicsComponentTest extends Specification with ReportsComponents {
"ReportsDemographicsComponent" should {
s"return empty list of $DeviceStatistics for an inexistent deliveryId" in DBUnitTestsUtils(2) {
accountId => implicit session =>
val service = new ReportsDemographicsService(accountId)
val res = service.deviceStatistics(-1)
res.size mustEqual 0
}
}
I have tried restarting Intellij, sbt, cleaning project, but to nu success. When running tests from the sbt command line, everything is OK.
In my case closing Idea and regenerating the projec setup by issuing
sbt gen-idea
Note:
You have to put this line into project/plugins.sbt to have the command:
addSbtPlugin("com.github.mpeltonen" % "sbt-idea" % "1.6.0")

The build was working fine previously so I wonder if it's an environmental issue.
Based on this PasteBin I know I'm not the first person to see this issue: http://pastebin.com/VtFy12UJ
Have you tried compiling outside of Intellij to see if that fixed the issue?
It's probably because you have a tuple with more than 22 items. Relevant Scala ticket: https://issues.scala-lang.org/browse/SI-9572
Double check your code.

Using Google Caliper with Scala

I am trying to use Caliper with Scala(2.10) in Eclipse Juno(4.2). For the start I've set up a benchmark that simply iterates a foreachloop over an array.
import com.google.caliper.Param
import com.google.caliper.SimpleBenchmark
class Benchmark extends SimpleBenchmark {
#Param(Array("10", "100", "1000", "10000"))
val length: Int = 0
var array: Array[Int] = _
override def setUp() {
array = new Array(length)
}
def timeForeach(reps: Int) = {
var result = 0
array.foreach {
result += _
}
result
}
When I start the benchmark with:
object myRunner {
def main(args: Array[String]) {
Runner.main(classOf[Benchmark], args)
}
}
I get these exceptions that I dont understand
0% Scenario{vm=java, trial=0, benchmark=Foreach, length=10} Failed to execute java -cp C:\Users\bob\workspace\myBenchmark\bin;C:\Users\bob\workspace\caliper\caliper\target>\classes;C:\Users\bob\workspace\caliper\caliper\target\test-classes;C:\Users\bob\.m2\repository\com\google\code\findbugs\jsr305\1.3.9\jsr305-1.3.9.jar;C:\Users\bob\.m2\repository\com\google\code\gson\gson\1.7.1\gson-1.7.1.jar;C:\Users\bob\.m2\repository\com\google\guava\guava\11.0.1\guava-11.0.1.jar;C:\Users\bob\.m2\repository\com\google\code\java-allocation-instrumenter\java-allocation-instrumenter\2.0\java-allocation-instrumenter-2.0.jar;C:\Users\bob\.m2\repository\asm\asm\3.3.1\asm-3.3.1.jar;C:\Users\bob\.m2\repository\asm\asm-analysis\3.3.1\asm-analysis-3.3.1.jar;C:\Users\bob\.m2\repository\asm\asm-commons\3.3.1\asm-commons-3.3.1.jar;C:\Users\bob\.m2\repository\asm\asm-tree\3.3.1\asm-tree-3.3.1.jar;C:\Users\bob\.m2\repository\asm\asm-util\3.3.1\asm-util-3.3.1.jar;C:\Users\bob\.m2\repository\asm\asm-xml\3.3.1\asm-xml-3.3.1.jar;C:\Users\bob\.m2\repository\junit\junit\3.8.2\junit-3.8.2.jar com.google.caliper.InProcessRunner --warmupMillis 3000 --runMillis 1000 --measurementType TIME --marker //ZxJ/ -Dbenchmark=Foreach -Dlength=10 org.example.Benchmark

I think I have some issues with the classpath but i am not sure.
I hope someone can help me :)
thanks in advance
Davram Bashere
It looks very much as though Caliper is running a new JVM and doesn't know that it needs to include the Scala libraries on the classpath.
This question describes how to run a Scala app with the java command on the command line. It should be a good starting point to solving this problem.
Even if you are editing scala sources in Eclipse you may still use sbt to run your code. Sbt is a great tool for managing your projects classpath in addition to providing a plugin system for providing the kinds of features like running Caliper benchmarks. I recently worked on a project where I needed just that and factored it out into an published sbt plugin. This may be of some help for you as well.
Thanks for your help. The problem was as expected the stupid classpath. I have downloaded the caliper project from googlecode and added the scala dependency. Now I've build my own jar-with-dependencies and it works quite fine.
Thanks for the answeres anyway :-)

Why does adding a "pending" break my Scala test?

The commented line below breaks my testing
import org.scalatest.WordSpec
class LSESuite extends WordSpec {
"An LSE market" should {
"round values" in {
val lse = new LSE {
}
assert(lse.getMarketName === "LSE")
//"min tick size" is (pending)
}
}
}
I receive the following error "An it clause may not appear inside another it clause" but I'm not sure how to interpret. Edit stack trace:
org.scalatest.TestRegistrationClosedException: An it clause may not appear inside another it clause.

Your 'pending' seems to be in an odd location. So you might see the same problem as I saw here: http://groups.google.com/group/scalatest-users/browse_thread/thread/177bbc520edc8fbd
