Changes not detected/included when building .modl from perspective-component using the newer open-sourced plugin

Using `./gradle zipModule` (or `./gradle build` w/dummy certificate) to build a module file, it will not detect and include changes done in `common`, `designer` or `gateway`. Only if a change has been done in `web` will a new modl file actually get created.

It will correctly generate a modl file upon first call after cloning the repo. But for subsequent calls, it does not detect that java/json files has changed.

Issue was not present in older version using `./gradle buildModule`

Could it be linked to the following issue?
https://github.com/inductiveautomation/ignition-module-tools/issues/28

On a related note:
Previously build number was added as `byyyymmddHH`, but for all builds with the newest version we only get `b0`. Is this as expected?

Steps to reproduce:
- Check out latest version of `perspective-component`
- Open git bash in repo on a PC running windows 10
- Run `./gradlew build` or `./gradlew zipModule` --> A .modl file gets created
- Make a change to `common/src/main/resources/*.json`
- Run `./gradlew build` or `./gradlew zipModule` --> No new .modl file will be created (unless old file was deleted manually first).

You can force it to create a modl file that actually contains the changes in `/common/src/main/resources` by deleting `/common/build` before running `./gradlew build`. This results in a new .modl file creation, that actually includes the changes made to the json file.
PS: designer does not notify that it requires restart - you must do that manually before changes can be seen.

Start by reproducing the behavior with ./gradlew build or ./gradlew zipModule, then inspect the build outputs under common/build and the changes in common/src/main/resources/*.json. Compare the newer commands with the older ./gradlew buildModule behavior and verify that changes in common, designer, and gateway are detected and included in the generated .modl file.
