Once I run mvn clean package I know that all phases of maven's lifecycle default prior to package (compile, test, package) , So I wonder is:

mvn clean compile package

The reason for the question is because I saw this in a code and although it is unnecessary, the question about performance was raised.

Yes, the command mvn clean compile package will execute the phase compile twice .

This can be easily checked in the maven log, as shown below, in the maven-compiler-plugin:3.3:compile snippet that appears:
