GCP error on version 2.3

[porfirioribeiro]

I followed the guide posted here https://egkatzioura.com/2018/04/09/host-your-maven-artifacts-using-google-cloud-storage/ to make deployment of my project to Google Cloud Storage.

It worked well but then i updated the version of this plugin to 2.3 and i got this error:

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project commons: Failed to deploy artifacts: Could not transfer artifact net.agroop:commons:jar:1.0.1 from/to my-repo-bucket-release (gs://agroop-mvn/release): Please configure you google cloud account by logging using gcloud and specify a default project

I don't know if something needs to change on the config or it's a bug.

For now i'll keep using 1.0

Same problem here, a bunch of severe exceptions when running mvn versions:display-dependency-updates gcloud authentication issues (so I'll keep using 1.7)

Do you use this environmental variable?
GOOGLE_APPLICATION_CREDENTIALS=/path/to/your/service/account/key.json mvn clean deploy
Also you can go for a settings configuration

<servers> <server> <id>repo-id</id> <configuration> <keyPath>/path/to/your/service/account/key.json</keyPath> </configuration> </server> </servers>
(Settings is on the latest version)

I am having the exact same issue with the latest google tools. I have tried authenticating with gcloud auth and also with gcloud auth application-default as am ad,om iser. I have also tried creating a service token with Storage Object Create and another service token with Storage Object Admin. None of them worked on versions 1.8, 2.2 or, 2.3

I just get this error

Version 1.7 does work though

@celandro
Unfortunately I fail to reproduce it.
However I use key from a service account.
Once I create a service account with the appropriate permissions I test the key using gsutil.
If everything ok I use
<servers> <server> <id>repo-id</id> <configuration> <keyPath>/path/to/your/service/account/key.json</keyPath> </configuration> </server> </servers>

Its working with GCP Service Account JSON based auth.

Key path base is from pom.xml location. And NOT from settings.xml
Also make sure, Service Account has appropriate rights.

However, request to update the plugin with gcloud based credentials.
