>                 Key: NIFI-5963
>                 URL: https://issues.apache.org/jira/browse/NIFI-5963
>             Project: Apache NiFi
>          Issue Type: Bug
>          Components: Core Framework
>    Affects Versions: 1.8.0
>         Environment: Rhel 7.5
> NiFi 1.8
> JDK 1.8.0_175
>            Reporter: Gideon Korir
>            Priority: Major

> I'm trying to build NiFi but I keep getting the following errors:
> {code:java}
> //@Before
> java.lang.AssertionError: Unable to delete target/content_repository/1 expected null, but was:<target/content_repository/1>
> at org.junit.Assert.fail(Assert.java:88)
> at org.junit.Assert.failNotNull(Assert.java:755)
> at org.junit.Assert.assertNull(Assert.java:737)
> at org.apache.nifi.controller.repository.util.DiskUtils.deleteRecursively(DiskUtils.java:47)
> at org.apache.nifi.controller.repository.TestFileSystemRepository.setup(TestFileSystemRepository.java:77)
> //@After
> java.lang.NullPointerException
> at org.apache.nifi.controller.repository.TestFileSystemRepository.shutdown(TestFileSystemRepository.java:87){code}
>  
> I've traced this to the multiple test methods trying to modify the content repository concurrently. When I run the tests 1 by 1 they all pass; to make them work with maven build I've made the following changes:
> {code:java}
> private final File rootFile = new File("target/content_repository/" + UUID.randomUUID().toString());
> {code}
