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

Answer 1

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

Answer 2

A fix for this issue is included as part of the Artifactory Plugin 2.8.0 : https://www.jfrog.com/jira/browse/HAP-829

Answer 3

According with other responses, you have 2 options:

• Update your Artifactory plugin to 2.8.0 version or ++ because this issue is solved in the 2.8.0 version .
• Use a workaround, installing Git plugin for Jenkins .

In these 2 options you need to update or install plugins so you need to restart your Jenkins installation.Restart Jenkins usually takes some minutes.

I recommend you to update your Artifactory plugin for solve this issue and posible future issues.
