Compilation Failure: "Could not create parent directories" for ValidTestCases.java in ttt-ttv module

[cfadamp]

During the compilation of the ttt-ttv module in the Timed Text Toolkit project, the build fails with the following error:
error while writing com.skynav.ttv.w3c.ttml2.validation.valid.ValidTestCases: could not create parent directories

This issue appears to be related to a failure in creating the necessary directories during the testCompile phase, as indicated in the Maven build logs. The problem prevents the successful compilation of the module, causing the overall build to fail.
The issue also persists with the ttt-ttpe module.

Verified filesystem permissions and available disk space.
Attempted to clean and rebuild the project using mvn clean install.
The issue persists despite ensuring a writable environment.

The full compile log is attached for reference. compile_issue.log

My system:

>mvn -version
Apache Maven 3.8.8 (4c87b05d9aedce574290d1acc98575ed5eb6cd39)
Java version: 1.8.0_241, vendor: Oracle Corporation
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

To temporarily resolve the issue, I renamed ttt\ttt-ttv\src\test\ and ttt\ttt-ttpe\src\test\ folders and the build runs successfully.
