> Key: NIFI-3454
> URL: https://issues.apache.org/jira/browse/NIFI-3454
> Project: Apache NiFi
> Issue Type: Bug
> Components: Tools and Build
> Affects Versions: 1.1.1
> Environment: Mac OS X ( any version ) Java 1.8.0_31 Maven 3.3.9
> Reporter: Otto Fowler
>
> DS_Store files [https://en.wikipedia.org/wiki/.DS_Store] may be present in
> any directory on Mac OS X.
> Any call made to getURLsForClasspath or getCustomClassLoader passing
> directories an not paths to jars for modules will return these files as urls
> unless they are specifically filtered out using the FileNameFilter parameter.
> The FileNameFilter parameter to these functions can be used to protect
> against this, and be sure the URL's returned are for the expected items. In
> fact there is a function getJarFilenameFilter in the TestClassloaderUtils
> already, that is used by the getCustomClassloader tests.
> This function should be used in all of the tests that pass in directories and
> not paths that are to jar files. Without it, NiFi builds that enable tests
> will fail on Mac OS X if .DS_Store files exist in the testing directory.
> This problem also effects TestIdentifyMimeType.java, where it is doing a
> directory listing, and should ignore "." files.
