This second example updates the module declaration to declare a dependency on module org.astro. Module org.astro exports the API package org.astro.
Note: in case one of the below .sh script fails due to the tree command, please take a look at Download and install the tree and wget command section in the README.md file and apply the appropriate solution.
Perform the below commands to see the contents of the respective sources contained in the src folder:
$ tree -fl src
or
$ cmd //c "tree /f /a src" (for Windows users)
Perform the below commands to see the contents of the respective Java classes contained in the src folder:
$ cat src/org.astro/module-info.java
$ cat src/org.astro/org/astro/World.java
Module org.astro exports the package org.astro (see src/org.astro/module-info.java for more details).
$ cat src/com.greetings/module-info.java
$ cat src/com.greetings/com/greetings/Main.java
Module com.greetings imports the package org.astro (see src/com.greetings/module-info.java for more details).
The sources are compiled into the folders mods/org.astro and mods/com.greetings with the following commands:
$ ./compile.sh
And we run the example with the following command:
$ ./run.sh
Check the contents of both these script files (use the cat command or a text editor) to see what they are doing and why - interesting instructions and information in there.
See ../01_Greetings/README.md to learn more about package and module naming conventions and how to avoid confusions between them.
