GCloud permission error when deploying to Google app engine flexible - maven

Question

I am trying to deploy my spring boot app to app engine via Jenkins using Maven. After maven has built the package, I am using "mvn install appengine: deploy" in the execute shell in the Build step. However, I get the following error when it is built,
GCLOUD: ERROR: (gcloud.app.deploy) Permissions error fetching application [apps/microservice-qa]. Please make sure you are using the correct project ID and that you have permission to view applications on the project.
Detailed error trace:

I have checked the permissions in the server for the key/user used to run gcloud commands, they both have full rights. However I still get the above error.
Also, is there any other plugin in Jenkins or any other tool (like jenkins to manage builds and deploy to app engine) to do the same?
Any help would be greatly appreciated. Thanks.

Answer 1

Since your Jenkins Server might not be configured with your project, use following commands in your jenkins job configuration:
Execute shell:
#!/bin/sh
gcloud -q auth activate-service-account --key-file=${PROJECT_KEY.JSON}
gcloud -q config set project ${PROJECT_ID}
mvn appengine:deploy
Also, for 'gcloud' to be available on Jenkins server, you would have to install plugin 'Google Deployment Manager Jenkins Plugin' in Jenkins.
