When I tried to compile simple typesafe' akka program (scala 2.10, akka, 2.1.0):
scalac -cp "akka-actor_2.10-2.1.0.jar:akka-camel_2.10-2.1.0.jar" write2.scala
error: bad symbolic reference. A signature in package.class refers to term apache
in package org which is not available.
It may be completely missing from the current classpath, or the version on
the classpath might be incompatible with the version used when compiling package.class.
error: bad symbolic reference. A signature in package.class refers to term camel

write2.scala:21: error: bad symbolic reference. A signature in package.class refers to term model

val mina = system.actorOf(Props[MyEndPoint])
three errors found
The code on line 21:
val mina = system.actorOf(Props[MyEndPoint])
(The same program was compiled correctly in Eclipse, so the source code is OK)
Most likely some jar file is missing in -cp variable. The question is what mean that strange/useless error message.
Thanks, Tomas
The message says "There's no package org.apache
in my classpath, and I need it while reading file package.class
". Pass -Ylog-classpath
to scalac
and look at what is the real classpath that gets to the compiler.
To me it was JDK not set on PATH neither JAVA_HOME
You can add JAVA_HOME to point to your JDK root folder and add jdk/bin folder (wich inludes javac) directly to the path.
You can refer to the Oracle docs for instruccions on how to add the path http://docs.oracle.com/javase/7/docs/webnotes/install/windows/jdk-installation-windows.html
