Can't get Scala to recognize commons-logging-1.1.2.jar

Question

I am running a program that requires the use of commons-logging-1.1.2.jar. When I try to compile it using:

scalac -classpath ~/jars/hadoop-core-1.2.1.jar:~/jars/commons-logging-1.1.2.jar:. HDFS_Test.scala

I get an error that says:

warning: Class org.apache.commons.logging.Log not found - continuing with a stub.

I know the class is in the jar but it still doesn't find it. Any idea what I could be doing wrong?

Answer 1

Bash only expands tildes in arguments when they are at the start of a word. Confusingly, bash does expand tildes after colons in variables , so CLASSPATH=~/jars/hadoop-core-1.2.1.jar:~/jars/commons-logging-1.1.2.jar scalac ... should work, but if you want to use a command line argument you'll have to expand it by hand.

Answer 2

Don't know why this worked but I replaced the ~ with the actual path and it cleared that error. ~ worked with the 1st class, but for some reason the 2nd class needed the full path.
