Error using Artifactory plugin for Flat property from Jenkins

Question

Jenkins 2.7.2 Pipeline job is not working for 'Flat property' in downloading schema.

While downloading artifacts from generic Artifactory repository (rb-artifactory), Jenkins pipeline job is throwing this error:

java.lang.NoClassDefFoundError: org/eclipse/jgit/util/StringUtils

I request for your support to resolve this error.

We have the following download schema:

def ar_download_logs = """{
  "files": [
    {
      "pattern": "${ar_url}/out/*",
      "flat": "1",
      "target": "logs/"
    }
  ]
}"""
def buildInfo1 = ar_server.download(ar_download_logs)

"flat": "1" causes the problem while converting from String to Boolean, which uses StringUtil and causing an exception java.lang.NoClassDefFoundError.

How to establish dependencies between some of StringUtils package for Artifactory Plugin: 2.5.1 to use string to Boolean conversion?

If you take a look at the following source code where the exception occurs, then it’s a Line 79 of GenericDownloadExecutor.java as given by the stack trace.

https://github.com/jenkinsci/artifactory-plugin/blob/master/src/main/java/org/jfrog/hudson/pipeline/executors/GenericDownloadExecutor.java

boolean isFlat = file.getFlat() != null && StringUtils.toBoolean(file.getFlat());

I also would like to share a plugin that are used for the project:

Artifactory Plugin: 2.5.1
Groovy : 1.29
Ivy Plugin : 1.26
Pipeline : 2.2
Pipeline: Groovy : 2.7
Pipeline: Job : 2.3

I am trying to get an account on the JFrog JIRA to file this as a bug. I also attempted to file an Issue on the Github repository but it looks like Issues are not enabled for this project. A painful hack might involve adding the org.eclipse.jgit JAR inside of the git-client plugin classpath, which many Jenkins have installed. — Brian Ray
should read "inside of the git-client plugin to the classpath," The permanent fix they might implement is to use commons-lang.BooleanUtils#toBoolean instead of the org.eclipse.jgit equivalent. — Brian Ray

Installing git plugin solves the issue.
In order for this to take affect Jenkins must be restarted after the installation.
