Well, it's nothing business with your settings of minimatch. It's just not work for that build task. Certainly, you can also doulbe check your minimatch with Copy Files task to verify this.
For now, you can avoid these issues by instead using the Copy Files step and the Publish Build Artifacts step.
Note: If it's still not working on copy files step, you should pay attention to the architecture of file when using minimatch. There must be something wrong on it.
