No classes found in classes folder inside war

Question

I converted my eclipse project to maven by creating a pom.xml file. I built the .war file by maven build command by specifying the goal

 clean compile install

and it build successfully. Now when I am running it on appache tomcate it throws no class found exceptions as I check .war/WEB-INF/classes folder is empty. Why classes folder is empty? Is this the reason why .war is not running on apache.

Please let me know if you need any further details

Answer 1

It is very hard to know the exact problem with so few details, however my guess would be that you have the wrong directory structure. Your code must be in the src/main/java/packagepath directory otherwise maven will not be able to find it and will create an empty jar/war.

As an additional note, the compile phase is included when you invoke the install phase so you do not need to explicitly call it.
