When I try to create allure report by allure-jenkins-plugin I get such error:

xml-file created by allure is valid (I may create correct report with maven goal "site" with the same xml), so the problem must be in jenkins plugin.

I have maven 3.2.5 installed, settings.xml exists in ~/.m2 directory and seems to be correct.

What may be the reason of such error? Seems that it's somehow connected with maven settings.

Looking at the code of the plugin and `AetherUtils`, it's not really clear why this happens. The plugin seems to have some poor release management practices, but it seems that (unlike most Jenkins plugins) you should try reporting this as a bug here: https://github.com/allure-framework/allure-jenkins-plugin/issues — Christopher Orr, May 01 '15 at 13:59

It might happen due to :

Allure is not installed in the Jenkin.

STEPS:

Go to Manage Jenkins > 
Global Tool Configuration >
Allure Commandline > 
Add Allure Commandline > 
Uncheck "Install automatically"

Download the latest allure commandline from maven repo - https://repo.maven.apache.org/maven2/io/qameta/allure/allure-commandline/

Unzip the file and provide the location

Installation directory : C:\allure-2.17.2 (I am using windows, jenkin)

The problem was in maven settings.xml file, in

<activeProfiles>

section. It contained profile, that in fact didn't exist. Removing this profile solved the problem.

This error happens when Allure Commandline is not installed on Jenkins agent.

I had such error when i forgot to set Name of the Allure Commandline installation in "Manage Jenkins" -> "Global Tool Configuration". For some reason in this case Allure Commandline distribution is not pushed to the agent to be installed on it.
