  hi

  Can you share your gulpfile.js file?

  No problem, thanks for getting back to me. Note the small function at the end which makes the files editable. This gets around the TFS locking issue for bundle generation.

  Hi

  The gulpfile.js is no problem. Have you tried the zero demo project?

  Hi,

  OK I did some more investigation on this. It works correctly if I run it locally on my dev machine. But when run in devops, the build process completes without errors but the files are not changed. I am still trying to ascertain the cause, so if anyone else has experienced the same issue, I would be interested in hearing how it was resolved.

  Hi @compassinformatics17

  Is your DEV and DevOps environments has the same Node version ?

  Hi Sorry for the late reply.

  I'm using Yarn to handle dependencies as specified in this AspNetZero Tutorial. All works fine but the files are not changed on the azure version.

  Below are a few images detailing the config and build task output in DevOps. It runs fine but the JS files are not minified in the artefact once the build completes on DevOps. I cannot see what's amiss and why the files are not being minified since all appears correct to my eyes.

  

  

  

  

  

  

  

  Thanks, Barry.

  Hi @compassinformatics17

  Does the min versions of the files exist in your Azure environment before you run the npm run build command ? If so, can you try to delete one of those min files and run the pipeline again ? This might be related to a file write permission.

  Thanks,

  Hello @compassinformatics17 and @ismcagdas

  The gulp task in my azure pipeline previously working fine but as it was taking too much time and we didn't have frequent changes in theme, I disabled that task. But now after enabling I am facing similar issue and the files are not getting minified. In Visual Studio using Task Runner gulp file makes minified files and applies theme related changes but it does not work in the Azure DevOps pipeline.

  Did you guys finally found any workaround in the pipeline task or fix? Please advise.

  Thanks.

  Hi @ISTeam

  Could you check if files in the output folder are cleared before creating new bundles ?

  Thank you for your reply @ismcagdas

  Unfortunately I am not sure which output folder you are mentioning. I tried to manually delete entire wwwroot directory from the deployment folder on our on-premises machine but that didn't help.

  The CI pipeline I have created last year with mostly v8.1.0 was using graphical interface in Azure DevOps as per the documentation. So, I tried to set 'Source and Output directory' cleaning suggested in this SO post answer.

  After two release I verified that all the CSS/JS including min files under the wwwroot subdirectories are updated but still the header title and its padding are somewhat different in the production.

  But this is how it looks in development env and

  something different in production

  @Update: Finally I found that it was because of Visual Settings => Subheader => Subheader style was different. In dev it was "Solid" and in production it was "Transparent" causing the padding like difference. Wondering as this was the root cause of the problem and initially we guess that this setting might be something related to background color only!
