JavaGradleWorkflow fails with Gradle sub-project dependency

**Description:**
I have a repo of multiple Gradle modules. One module contains all shared code, and all other modules depend on the single shared module.

Prior to moving the shared code into it's own module, sam build and deploy were working fine. Now that the module of shared code is split out, same build is failing.

**Steps to reproduce the issue:**
1. Setup 2 Gradle modules(moduleA and moduleB)
2. Let moduleB be deployed to a Lambda function and depend on moduleA
3. Run `sam build` on moduleB and the build will fail

**Observed result:**

```
**Expected result:**
Successful SAM build!!

**Additional environment details (Ex: Windows, Mac, Amazon Linux etc)**
Reproduced this both on MacOS and Linux(Fedora)

Beginne mit aws_lambda_builders/workflows/java_gradle/actions.py und gradle.py und konzentriere dich auf JavaGradleWorkflow:GradleBuild und den Gradle-Aufruf. Reproduziere das mit sam build für moduleB beschriebene Zwei-Modul-Setup und überprüfe anschließend, dass die gemeinsam genutzte commons.jar verfügbar ist und der SAM-Build erfolgreich abgeschlossen wird.
