---------------------------------
Summary: NiFi parent pom dependency management forcing versions to
align defeating classloader isolation
Key: NIFI-4936
URL: https://issues.apache.org/jira/browse/NIFI-4936
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework, Extensions, Tools and Build
Affects Versions: 1.5.0, 1.4.0, 1.3.0, 1.0.1, 1.2.0, 1.1.0
Reporter: Joseph Witt
Assignee: Joseph Witt
Fix For: 1.6.0
the top level pom in nifi has a massive dependency management section. this
was used initially to help enforce consistent usage of dependencies across nifi
but this also can defeat the purpose of the classloader isolation offered by
nars. We need to push down dependency version declarations to the nar levels
where appropriate.
there have been reported issues of defects happening due to us using much newer
versions (or sometimes older) of dependencies due to this dependency management
model. By pushing declarations down to the proper scope each nar/etc.. can use
the specific versions of components it needs and we'll stop introducing issues
by forcing a different version.
