Reproduction steps

I just have one computer to run the web UI tests, when i build continuous(like 10 times using different parameters), occasionally when build starts, the jenkins console give me the PermissionError and says couldn't delete the allure-dir,because some other program using it.

Here's my pytest params:
pytest.main(
[f'-m {run_marks}',
'--clean-alluredir',
'--alluredir', allure_dir,
'-n', multiprocess,
'--reruns', reruns,
'--reruns-delay', reruns_delay,
'--dashboard']
)

Expected Results

continuous build in jenkins success

Actual Results

got PermissionError

Anything else?

when the testcases finished, jenkins allure-plugin start to generate allure report, but when the report finished, occasionally allure-dir folder is still in use, at the same time next build starts, and the pytest params has "--clean-alluredir".
i guess this is the reason, so i add following code:

try:
    shutil.rmtree(allure_dir)
except PermissionError:
    time.sleep(5)

when build starts, try to remove allure-dir first, if got PermissionError, force wait 5 second, but this seems doesn't work.

could anyone help me.
