无法通过Ubuntu 16.04 LTS上的Ansible with Jenkins_作业创建Jenkins作业

我试图在Ansible中使用jenkins_作业模块，它不断抛出错误

无法创建作业，不支持带有编码声明的Unicode字符串。请使用无声明的字节输入或XML片段。

我使用main.yml调用的文件tasks/add_job.yml中的以下任务触发此错误：

- name: Install CloudBees Folder for {{ item }}
  jenkins_job:
    config: "{{ lookup('template', 'config.xml.j2') }}"
    name: {{ item }}
    password: "{{ jenkins_admin_password }}"
    url: "http://{{ jenkins_hostname }}:{{ jenkins_http_port }}"
    user: "{{ jenkins_admin_username }}"

tasks/add_jobs.yml多次调用此任务，如下所示：

- name: Include job array via vars.
  include_vars:
    file: jobs.yml

- name: Install jobs.
  include: add_job.yml
  with_items: "{{ jenkins_jobs }}"

var文件如下所示：

jenkins_jobs:
  - Job1
  - Job2

我的配置文件位于templates目录中，如下所示（我尝试了许多不同的XML文件，最后尝试使用ansible GitHub项目：

<?xml version='1.0' encoding='UTF-8'?>
<project>
  <actions/>
  <description></description>
  <keepDependencies>false</keepDependencies>
  <properties>
    <jenkins.model.BuildDiscarderProperty>
      <strategy class="hudson.tasks.LogRotator">
        <daysToKeep>1</daysToKeep>
        <numToKeep>20</numToKeep>
        <artifactDaysToKeep>-1</artifactDaysToKeep>
        <artifactNumToKeep>-1</artifactNumToKeep>
      </strategy>
    </jenkins.model.BuildDiscarderProperty>
    <org.jenkinsci.plugins.gitbucket.GitBucketProjectProperty plugin="gitbucket@0.8">
      <linkEnabled>false</linkEnabled>
    </org.jenkinsci.plugins.gitbucket.GitBucketProjectProperty>
  </properties>
  <scm class="hudson.scm.NullSCM"/>
  <canRoam>true</canRoam>
  <disabled>false</disabled>
  <blockBuildWhenDownstreamBuilding>false</blockBuildWhenDownstreamBuilding>
  <blockBuildWhenUpstreamBuilding>false</blockBuildWhenUpstreamBuilding>
  <triggers/>
  <concurrentBuild>false</concurrentBuild>
  <builders/>
  <publishers/>
  <buildWrappers/>
</project>

在出现这个错误之前，我在运行jenkins_作业时遇到了很多问题，因为它一直在抱怨缺少依赖项，所以下面是我在Ubuntu 16.04.2 LTS上安装的包列表

jenkins_job_dependencies:
  - build-essential
  - python-pip
  - python3-pip
  - libffi-dev
  - libssl-dev
  - libxml2-dev
  - libxslt1-dev
  - python-dev
  - python3-dev
  - python-lxml
  - python3-lxml
  - python-jenkins
  - python3-jenkins
  - python3-venv
  - git

这是

-vvv

输出

我尝试了许多xml声明的排列方式：包括它、删除它、使用utf-16等等，但似乎都不起作用。如果有任何提示，我将不胜感激。我很感激有许多其他方法可以通过Ansible（cUrl、cli等）创建作业我正在将我的项目移植到job dsl插件中，但如果我能使用一个“开箱即用”的Ansible模块来实现这一点，那就太好了

好的……这是我关于StackOverflow的第一个问题……如果我有任何错误，我表示歉意。

事实证明是ansible_python_解释器在我的主机清单中设置为

/usr/bin/python3

。当我将其设置为

/usr/bin/python

时，问题消失了。耶

…但这只是故事的一半。当我销毁并重新创建我的虚拟机时，它在第一步就失败了，因为Ubuntu 16.04LTS没有

/usr/bin/python

它只有

/usr/bin/python3

我不想创建符号链接或执行virtenv之类的操作…所以我只是在安装python2 dev apt包之后，但在运行jenkins_脚本模块之前，将ansible_python_解释器设置为

/usr/bin/python

。然后在运行脚本之后，我再次将其设置回原处

# Truncated playbook for brevity...
- name: Install dependency
  package: "name=python-dev state=present"

- name: Set the python interpreter to the symlink (which points at version 2.7)
  set_fact:
    ansible_python_interpreter: '/usr/bin/python'

- name: Do script thing.
  jenkins_script:
    script: "{{ script_var }}"
    user: "{{ jenkins_username }}"

  changed_when: true
  no_log: True

  set_fact:

如果我能找到jenkins_脚本模块的源代码在哪里，我会做一个pull请求来修复潜在的问题，但遗憾的是，我无法找出它在哪里
