[MDEPLOY-306] [REGRESSION] Could not acquire write lock

On Windows OS, project with 500 modules fails build on final module with deployAtEnd set to true.

```
Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:3.1.0:deploy (default-deploy) on project x: Execution default-deploy of goal org.apache.maven.plugins:maven-deploy-plugin:3.1.0:deploy failed: Could not acquire write lock for 'y'
```

Maven 3.9.0

I've used deployAtEnd in the past without issue (but not with Maven 3.9.0)

---

**Affects:** 3.1.0

Start by reproducing the Windows build described in the issue: Maven 3.9.0, a project with 500 modules, and deployAtEnd set to true. Focus on the final-module failure and the “Could not acquire write lock” message; done means the build completes without that lock error.
