Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:2.7:resources

When executing mvn install project packaging in idea, an error will be reported:, Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:2.7:resources (default-resources) on project k3: Cannot create resource output directory:xxxxxxxxthe resource path of the output file seems to be occupied.
My situation here is that I used xftp to upload files from this directory before, and the corresponding directory has been able to be occupied. Although the target directory was successfully deleted by executing the clean command in idea, when you received the corresponding module The target directory is not accessible.
At this point, turn off xftp and re-execute the install package.
