The task below does the job

&nbsp;&nbsp;- debug:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msg: "{{ lookup('file',  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'files/branches.txt').split()|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;product([version])|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;map('join')|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;join(' ') }}"

gives

&nbsp;&nbsp;msg: mhr-1.1-SNAPSHOT mtr-1.1-SNAPSHOT tsr-1.1-SNAPSHOT

In addition to this, you've said "each line add {{version}} to it".  
If there are more lines, e.g.

&nbsp;&nbsp;cat files/branches.txt  
&nbsp;&nbsp;mhr- mtr- tsr-  
&nbsp;&nbsp;xhr- xtr- xsr-  
&nbsp;&nbsp;yhr- ytr- ysr-

the task below iterates the lines

&nbsp;&nbsp;&nbsp;&nbsp;- debug:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msg: "{{ item.split()|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;product([version])|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;map('join')|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;join(' ') }}"  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;loop: "{{ lookup('file',  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'files/branches.txt').splitlines() }}"

gives

&nbsp;&nbsp;msg: mhr-1.1-SNAPSHOT mtr-1.1-SNAPSHOT tsr-1.1-SNAPSHOT  
&nbsp;&nbsp;msg: xhr-1.1-SNAPSHOT xtr-1.1-SNAPSHOT xsr-1.1-SNAPSHOT  
&nbsp;&nbsp;msg: yhr-1.1-SNAPSHOT ytr-1.1-SNAPSHOT ysr-1.1-SNAPSHOT

Hi Vladimir Botka ,  
thanks you so much for taking time to help , above works at debug level but I have to save it to a variable and . Loop it and download each file.

The file is in my host and Download happens in remote host .i tried the below task im still  
not able to achieve desired result.

- include\_vars:

file: releasevars.yml  
when: env == “dev”

- slurp:  
src: ‘{{item}}’  
register: input\_file\_content  
loop:

- “{{file}}”  
delegate\_to: localhost

- debug:  
msg: “{{ item[‘content’] | b64decode }}”  
loop: ‘{{ input\_file\_content[“results”] }}’

- set\_fact:  
files\_version: “{{ (input\_file\_content[‘content’] | b64decode).split(‘\n’) | map(‘regex\_replace’, ‘^(.+)$’, ‘\g\<1\>’ + version ) }}”

- name: Download artifact  
maven\_artifact:  
group\_id: com.devops.services  
artifact\_id: “{{ item[‘content’]| b64decode }}”  
version: 6.0.0-39-SNAPSHOT  
repository\_url: [https://nexus.com/repository/maven-snapshots](https://nexus.com/repository/maven-snapshots)  
username: user

Try this

&nbsp;&nbsp;&nbsp;&nbsp;- set\_fact:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;files: "{{ lookup('file','releasevars.yml').split()|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;product([version])|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;map('join')|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;list }}"

&nbsp;&nbsp;&nbsp;&nbsp;- slurp:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;src: "{{ item }}"  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;register: input\_file\_content  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;loop: "{{ files }}"
