Error while pushing app to cloud foundry: FAILED Error processing app file: The directory is not empty

Question

I am facing this error while pushing the spring app to the cloud foundry with the cf push command. Earlier it was being deployed just fine.

D:\Documents\PredixApps\locomotive\locomotive-ingestion>cf push Using manifest file D:\Documents\PredixApps\locomotive\locomotive-ingestion\manifest.yml

Updating app ehsan-locomotive-dataingestion-service in org username / space dev as username... OK

Uploading ehsan-locomotive-dataingestion-service... Uploading app files from: C:\Users\EHSAN~1.WAR\AppData\Local\Temp\unzipped-app070592951 Uploading 878K, 143 files Done uploading OK FAILED Error processing app files: remove C:\Users\EHSAN~1.WAR\AppData\Local\Temp\unzipped-app070592951\lib: The directory is not empty.

Answer 1

Sometimes there are issues on Windows where a lock on a file is not immediately released, or possibly other software (e.g. anti-virus software) has a lock on a file when the CLI tries to remove temporary files.
The CLI team is currently refactoring the cf push command and trying to reduce the number of temporary files created during the push process, which hopefully reduces the opportunity of this type of issue to occur.

I have encountered this same problem and fixed this by upgrading my CloudFoundry CLI from version 6.25.0 to version 6.32.0.

It was a bug with CloudFoundry CLI versions less than 6.32.0 per this reference https://github.com/cloudfoundry/cli/issues/1223
