Hi, This failure is caused by ```
Files with unapproved licenses: /home/jenkins/jenkins-slave/workspace/IoTDB-Pipeline_master/tsfile/src/test/resources/testTsFile.tsfile ``` But, this file should be removed after a UT but it does not. I think maybe in some UT, we forgot to close the file writer, so that the file could not be removed (only in Win OS). Hope we can reproduce it. I added the returned value check of `file.delete()` to check which UT fails to remove the file. The PR is [1] And, now I move all generated TsFiles in UTs to the target folder, which will be ignored by Maven. the PR is [2] 1. remember to check the returned value of file.delete(); and 2. do not generate any temporary files in src/ folder.
