Question

I have a Maven project with different modules like this:

• MyProject
  • testlib
  • common
  • client
  • commonserver
  • webserver

I can execute webserver inside Eclipse’s tomcat without problem, I can compile it with Maven without problems but when I try to mvn tomcat:run webserver module, it complains it does not find a class defined in common:

SEVERE: Context initialization failed
java.lang.NoClassDefFoundError: com/myproject/core/MyException
    at java.lang.Class.getDeclaredConstructors0(Native Method)
    at java.lang.Class.privateGetDeclaredConstructors(Class.java:2404)
    at java.lang.Class.getDeclaredConstructors(Class.java:1853)

    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBeanInstance(AbstractAutowireCapableBeanFactory.java:935)

I have dependencies set in the pom (and it compiles so I don’t know what’s going on).
Thanks in advance.

Answer 1

The problem was I was running from parent folder like this

mvn -pl webserver tomcat:run

If I do

cd webserver
mvn tomcat:run

then it works
