Hi,
In option 1:
3. Add requires clauses for all packages contained in analytics.jar and ojdbc8.jar that are directly referred to by classes in reports.jar in its module-info.java.
But why? analytics.jar and ojdbc8.jar are automatic modules. So you have to require the two jar files in module-info.java:
requires analytics;
requires ojdbc8;
And later you can import all packages you need inside your report project. No need to require any packages in module-info.java.
Here is another example:
module-info.java
Main.java

for (CSVRecord record : records) {
String name = record.get(1);
System.out.println(name);
}
in.close();
} catch (IOException e) {
}
}
