But I check my jar that the scala-lang.jar is in the lib folder, so it should be in classpath. But why here it can not find it?
Jeff Zhang
Please read question classpath-including-jar-within-a-jar.
Sorry, I make a stupid mistake. Actually I run scala in hadoop, and call "hadoop -jar" rather than "hadoop jar", such a stupid mistake.

I'm currently having trouble running Junit tests created in Eclipse on IntelliJ.
My IntelliJ SDK is 1.8, the SDK of the project is 1.7, however, I'm not using any new features.
I've imported the project (properly, I hope) and the JUnit test along with the JDK is being shown in the "External Libraries" tab.
When I run my test I get an "initializationError", and when right clicking the "tests" directory and selecting "Run 'All Tests'" I get the error "No tests were found".
These are the Errors I get:

You need the library hamcrest-core-1.3 on your class-path. See Getting Started

A detailed answer for my approach is highly appreciated.
You error suggest that you're using a lower JVM version than the one the application was build. Try upgrading your java version

Error during sbt execution: java.lang.NoClassDefFoundError: scalax/io/Seekable
It could be that you need to install sbt;
try running "sbt" in command prompt/console,
If you get
Cannot find sbt launcher 0.13.0
Please download:
From http://typesafe.artifactoryonline.com/typesafe/ivy-releases/org.scala-sbt/sbt-launch/0.13.0/sbt-launch.jar
To /home/<your home directory>/.sbt/.lib/0.13.0/sbt-launch.jar
then, follow its instructions, everything should work
Open command prompt(Not Git-Bash prompt) and run the following commands....
play clean-all
play compile
play run
Server should be getting started.
Now come back to IDE(Eclipse) and refresh the project. If problem solved then njoy else try something else :)
May be project/plugins.sbt file you need to update.
I'd like to load dynamically a Class object defined by the Guava library from the Scala REPL. However, I observe different behaviors depending on the way I retrieve the Class definition:
scala> :cp guava-10.0.1.jar
Added '/Users/xxx/guava-10.0.1.jar'. Your new classpath is:
"/Users/rouvoy/Development/tools/axis/default/lib:/Users/xxx/guava-10.0.1.jar"
scala> Class.forName("com.google.common.base.Ascii")
res0: java.lang.Class[_] = class com.google.common.base.Ascii
The Class.forName(...) method works fine and manages to retrieve the Class object, but I would like to understand why, when using the ContextClassLoader, I am not able to locate the Class definition—while it works perfectly in Java?
scala> Thread.currentThread.getContextClassLoader.loadClass("com.google.common.base.Ascii")

The classloading is subtly different between Scala and Java. When you specify -cp to the scala executable (script or .bat), it doesn't get added to the base classpath, it only gets added to the Scala Class Loader. I suspect the same is true for the REPL when you specify :cp.
To really add something to the java classpath, use the -toolcp option to scala or scalac.
See my answer to: scala classloaders confusion.
I am on windows 7 64 bit and using eclipse indigo. I downloaded the latest version of jogl 2 and i have created an eclipse project following this link
https://sites.google.com/site/justinscsstuff/jogl-tutorial-2
this tutorial is old as the jars in the jogl download dont match and i have included all the jars and for each jar set the native libraries directory. I have written a small jogl test program that creates a GLProfile, GlCapabilities and an awt frame. I get this exception:

Exception in thread "main"
seems like im missing a jar..could any let me know what im doing wrong here?
I am using the jogl-all.jar from Matlab 2014a. The error above disappeared and everything run smoothly when I added the library glugen-rt.jar.
(remember also to -Djava.library.path=/path/to/native/files when you execute your application, in my case this was -Djava.library.path=/Applications/MATLAB_R2014a.app/bin/maci64)
Try to add gluegen as well.
For example
<dependency>
<groupId>org.jogamp.jogl</groupId>
<artifactId>jogl-all</artifactId>
<version>2.0-rc11</version>
</dependency>
AND
<dependency>
<groupId>org.jogamp.gluegen</groupId>
<artifactId>gluegen-rt-main</artifactId>
<version>2.0-rc11</version>
</dependency>
I had a similar problem with the JOGL jar files. See here. Also, check out the tutorials on the jogamp wiki (by the looks of it Wade is pretty active on the wiki).
