Hi Renato, This is a problem which has come to the surface in the last while and yes it is most certainly a bug which needs rooted out and fixed!
I'm currently investigating gora-tutorial pom.xml [0], which has next to no dependencies apart from data store implementations which are used within the tutorial. It also seems to include a rather random reference to the build-helper-maven-plugin, which I don't understand as the src/main/java directory is effectively acting as src/examples/java does in other modules. I made a commit yesterday which I thought addressed some early problems within the tutorial, but it seems that there is still some digging to be done here. This is most likely to have happened during the transition from Ant/Ivy to Maven for build lifecycle. I have work to do for the next tow hours but I will certainly have a look into this again tonight. Thanks for reporting Lewis [0] http://svn.apache.org/repos/asf/gora/trunk/gora-tutorial/pom.xml On Thu, May 17, 2012 at 5:32 PM, Renato Marroquín Mogrovejo <[email protected]> wrote: > Hi all, > > I am starting a new thread on the user´s list (: > I started doing this tutorial [1] so I can see gora actually working, > but I am getting this classpath error when I try to execute the > logManager: > > Exception in thread "main" java.lang.NoClassDefFoundError: > org/apache/gora/tutorial/log/LogManager > Caused by: java.lang.ClassNotFoundException: > org.apache.gora.tutorial.log.LogManager > at java.net.URLClassLoader$1.run(URLClassLoader.java:217) > at java.security.AccessController.doPrivileged(Native Method) > at java.net.URLClassLoader.findClass(URLClassLoader.java:205) > at java.lang.ClassLoader.loadClass(ClassLoader.java:321) > at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) > at java.lang.ClassLoader.loadClass(ClassLoader.java:266) > Could not find the main class: > org.apache.gora.tutorial.log.LogManager.
