Are these errors in the source code normal?

So I forked their repository and made a git clone but when I open the project my IDE(IntelliJ) says that there are errors in the code.

An example of this are some of the pom files


IntelliJ says that properties in parent are prohibited

Another example is the following one where the error “cannot resolve symbol liquibase-pro” is prompeted


Is it normal?

@fabiopires10 ,

IntelliJ is throwing up issues, but could you try using commandline? that way we can diagnose if this is a configuration issue with your IDE vs an issue with the liquibase github project.
