Hello guys,
Please, I was trying to build a simple maven project but ran into some
difficulty. I was checking out the instructions from this site->
`http://www.mkyong.com/hibernate/quick-start-maven-hibernate-mysql-example/`
<http://www.mkyong.com/hibernate/quick-start-maven-hibernate-mysql-example/%60>
but when I took a look at the structure, I discovered in my project
structure, I couldn't find the .project and the .classpath files. I
only found the pom.xml. When I ran the project, I hit an eror:
You don't need .project and .classpath files unless you want them to get
built
as Eclipse projects as well.
Exception in thread "main" java.lang.NoClassDefFoundError:
com/henry/directory/App
Caused by: java.lang.ClassNotFoundException: com.henry.directory.App
It is looking for com/henry/directory/App.class in the classpath but
cannot find it.
I strongly recommend you to study the "Maven Basics 1" under "Java
development tools" course
along with 8623_tools_build_maven1.zip.
