# using another project's class

Scenario:

needs the Project B's class files in Project A.

<https://stackoverflow.com/questions/33856571/how-can-i-use-classes-from-other-project-with-maven-classnotfoundexception-and>

1. could use B's jar file as external library in A.
2. try to remove`<packaging>war</packaging>`from B? Maven's default packaging is`jar`, and this is what you need for B.

   Plus, add B to the`dependencies`of A.

   * Build B project. use

     `mvn clean install`

     , that would install B's JAR+POM in your local repository (.m2).
   * Verify it is there... Then Maven will be able to find it, so you will not get the error "Could not find artifact de.qufis:CentwertApp"
   * Build A.

   Usually, dependencies are of type JAR. If B **must** be a WAR.
