How to add several jars to module path?

I am having the following situation:

Module Address:

module org.abondar.experimental.address {
    exports org.abondar.experimental.address;
}

Module Person:

module org.abondar.experimental.person {
    requires org.abondar.experimental.address;
    exports org.abondar.experimental.person;
}

I am building them using Maven, so every module has it's own target dir with jar file.

I am trying to run module Person which has main class like this

java --module-path Address/target/Address-1.0.jar;Person/target/Person-1.0.jar -m org.abondar.experimental.person/org.abondar.experimental.person.Main

But I am getting permission denied. How do I need to set up module path including several modules?

Well trying this on one of my projects with MacOS, I almost ended up with something similar as this - 

zsh: permission denied: .../.m2/repository/test/test/1.0.0-SNAPSHOT/test-1.0.0-SNAPSHOT.jar
zsh: permission denied: .../.m2/repository/org/slf4j/slf4j-log4j12/1.7.12/slf4j-log4j12-1.7.12.jar
zsh: permission denied: .../.m2/repository/org/slf4j/slf4j-api/1.7.12/slf4j-api-1.7.12.jar

The reason for that error is that the paths to the JARs are specified as a command to be executed on MacOS instead.

If you consider the module path as a list of directories for MacOS(might be Unix in general) it doesn't match the java tool documentation. Instead what you could seek for is 

java --help

which states

--module-path <module path> ... A : separated list of directories, each directory is a directory of modules.

and in that case the command that shall work for you shall be :-

java --module-path Address/target/Address-1.0.jar:Person/target/Person-1.0.jar -m org.abondar.experimental.person/org.abondar.experimental.person.Main
