I’ve a Java project that just compiles fine on a Mac (OS-X Mountain Lion). When I try to compile the same project on an Ubuntu machine it fails.<\/p>\n

Basically it’s complaining that it cannot find a class. However, the class is present in the maven classpath. I verified that after running mvn<\/code> with the -X<\/code> switch.<\/p>\n

(see     612 [DEBUG]  \/home\/c\/.m2\/repository\/org\/apache\/camel\/camel-twitter\/2.11.0\/camel-twitter-2.11.0.jar ) below. \n<\/code><\/pre>\n
I even deleted my $HOME\/.m2 repository so that it would download everything again. But it still fails.<\/p>\n
Any idea what I’m missing here ?<\/p>\n
Here is my environment on Ubuntu.<\/p>\n
mvn -version\nApache Maven 3.0.4\nMaven home: \/usr\/share\/maven\nJava version: 1.6.0_32, vendor: Sun Microsystems Inc.\nJava home: \/usr\/lib\/jvm\/jdk1.6.0_32\/jre\nDefault locale: en_US, platform encoding: UTF-8\nOS name: \"linux\", version: \"3.2.0-40-generic\", arch: \"amd64\", family: \"unix\"\n<\/code><\/pre>\n
