synchronize error

[John Scancella]

Hello,

I am having trouble executing this playbook

---

- hosts: chronam-servers

  vars:

    SOLR_VERSION: 4.10.4

    SOLR_HOME: "/opt/solr"

  tasks:

  - name: download solr {{SOLR_VERSION}}

    get_url: dest=/tmp/solr-{{SOLR_VERSION}}.tgz url=http://archive.apache.org/dist/lucene/solr/{{SOLR_VERSION}}/solr-{{SOLR_VERSION}}.tgz

  - name: untar solr {{SOLR_VERSION}}

    unarchive: src=/tmp/solr-{{SOLR_VERSION}}.tgz dest=/tmp creates=/tmp/solr-{{SOLR_VERSION}}

  - name: create solr user

    user: name=solr home={{SOLR_HOME}} shell=/bin/bash append=yes state=present system=yes

    become: yes 

  - name: copy example directory to {{SOLR_HOME}}

    synchronize: dest={{SOLR_HOME}} src=/tmp/solr-{{SOLR_VERSION}}/example/ recursive=yes owner=solr group=solr mode=0775

    delegate_to: "{{inventory_hostname}}"

    become: yes 

  - name: Copy chronam config files

    copy: dest={{item.dest}} src={{item.src}} 

    with_items:

      - { src: 'conf/schema.xml', dest: "{{SOLR_HOME}}/solr/collection1/conf/schema.xml" }

      - { src: 'conf/solrconfig.xml', dest: "{{SOLR_HOME}}/solr/collection1/conf/solrconfig.xml" }

    become: yes 

  - name: start solr

    service: name=jetty8 state=started

    become: yes 

I am getting the error:

           to retry, use: --limit @/home/ubuntu/solr.retry

What does "Boolean solr not in either boolean list" mean? How do I fix it?

Thanks
