The problem seems to be a ClassNotFound error for a class in Apache commons. There appears to be something wrong with your installation of maven.
What operating system are you using? With Ubuntu 14.04 64-bit or Fedora 20, please see this https://github.com/mesos/chronos/issues/211 . Also, some users in that community mention that common-lang.jar is missing in the default installation of Apache Maven 3.0.5. Somethings you could try: 1. Download the latest version of maven as a tgz from the repo, and run that binary. ie, ~/apache-maven-3.0.5/bin/mvn package instead of the usual 'mvn package' 2. Delete your maven cache directory. Typically, this is ~/.m2 3. Another workaround is to fix this by using a symlink to the installed version of apache commons so that you include the jar in the lib directory used by maven: cd /usr/share/maven/lib sudo ln -s ../../java/commons-lang.jar . <https://github.com/toudidel> Thanks, Jagadish On Mon, Feb 29, 2016 at 2:12 PM, Jeff Ramin <jeff.ra...@singlewire.com> wrote: > > Hi folks. > > I'm trying to get the hello-samza project running, so I can get acquainted > w/ samza: > > http://samza.apache.org/startup/hello-samza/0.10/ > > Following the instructions on that page, I'm receiving the error below on > the "mvn clean package" > step.
