Circular dependence Maven?

Question

If I add this to the POM, will it create a circular dependency? I tried this and what it seems. Here I do not understand. This is not a war file created at the end of the build.

 <dependency>
  <groupId>${project.groupId}</groupId>
  <artifactId>mywebapp</artifactId>
  <version>${project.version}</version>
  <type>war</type>
  <scope>provided</scope>
 </dependency>

My directory structure is root / functest, root / mywebapp.

Answer 1

It will create a cyclical dependence if it mywebappdepends on functest(or in transit depends on it). From the name, I would suggest that it functestis a test component, so this dependency will not exist.

As you have seen, it is permissible to replace properties with dependency declarations; Maven will fail if this leads to a loop.
