I have created a Dynamic Web Project on eclipse building a Rest API with wildfly on eclipse using Maven that perfectly runs locally, but I am experiencing some issues while trying to deploy my project on Heroku.
I have checked the heroku deploy:war and it works when deploying but gives a strange error message saying that heroku finds a problem trying to delete a temporary file because it is being used by another process.
Error:

I also found some info to try to deploy using a webapp runner but it is based on tomcat, and also using a plugin that goes like this:
<plugin>
<groupId>com.heroku.sdk</groupId>
<artifactId>heroku-maven-plugin</artifactId>
<version>3.0.3</version>
</plugin>
and after setting the app name in the pom.xml, and executing mvn clean heroku:deploy-war -e -X as it is stated on https://devcenter.heroku.com/articles/deploying-java-applications-with-the-heroku-maven-plugin it gives this error:

Thank you in advance to any of you who can give me any help!
heroku war:deploy
creates a temporary file that contains your project in a package that is understood by Heroku. This happens on your local machine. It tries to clean up those temporary files by deleting them.
I don't know which process might use this file causing the error, but as you noticed, this will not influence the deployment to Heroku itself.
The output of your heroku-maven-plugin
is interesting. It's not the Heroku plugin that fails, but Maven's own clean
plugin. Can you try running mvn heroku:deploy-war
and see if that works?
In any case, I logged a bug for this and will make it a warning instead of a crash when the temporary files cannot be deleted.
