------------------------------------------
Summary: Nifi Registry start fail with NoClassDefFoundError:
software/amazon/awssdk/auth/credentials/AwsCredentials
Key: NIFI-10363
URL: https://issues.apache.org/jira/browse/NIFI-10363
Project: Apache NiFi
Issue Type: Bug
Components: NiFi Registry
Affects Versions: 1.17.0
Reporter: Zoltán Kornél Török
Assignee: Zoltán Kornél Török
Fix For: 1.18.0
In https://issues.apache.org/jira/browse/NIFI-9848, the maven-assembly-plugin
version is increased 3.3.0 from 2.4.3 in nifi-registry.
Because of that some of the AWS libraries are not included into lib/spp
directory, which cause the following error, if nifi-registry.properties
contains encrypted values:

*Reproduce the issue*
# Download nifi-registry 1.17.0 binary
# Download nifi-toolkit 1.17.0n binary
# Uncompress it
# Configure nifi-registry.properties to encrypt some sensitive key. For
example I did the following:
{code:java}
nifi.registry.sensitive.props.additional.keys=nifi.registry.security.authorizers.configuration.file
{code}
# Execute this from conf directory:
{code:java}
../../nifi-toolkit-1.17.0/bin/encrypt-config.sh --nifiRegistry \
-b bootstrap.conf \
-k 0123456789ABCDEFFEDCBA98765432100123456789ABCDEFFEDCBA9876543210 \
-r nifi-registry.properties
{code}
# Start nifi-registry, the bootstrap log will contain the error and
nifi-registry won't start
*Suggested solution:*
Add {code}<include>software.amazon.awssdk:*</include>{code}
to nifi-registry-assembly dependencies.xml
*More details why this happens*
In nifi registy there are two libs which use software.amazon.awssdk:auth
dependency:
* nifi-property-protection-aws which use 2.17.106 version and that is used in
nifi-registry-properties-loader
* nifi-registry-aws which use 2.5.9 version
The maven-assembly-library use a maven-core lib, which returns the resolved
artifacts what the plugin use. In case of maven-assembly-plugin 2.4.3 the
resolved artifact is software.amazon.awssdk:auth:2.5.9 but the depTrail
contained a reference for nifi-registry-properties-loader, that is why 2.5.9 is
included in lib/spp path.
However in case of maven-assembly-plugin 3.3.0, the
software.amazon.awssdk:auth:2.5.9 depTrail contains reference for
nifi-registry-aws, that's why the necessary lib no longer included.
Probably in an another ticket, it would worth to adress the problem that some
of the aws libs in lib/spp versions are 2.17.106 but others resolved to 2.5.9
