I'm trying to run the datahub gms service for local development, the build went successful with the below command

./gradlew :metadata-service:war:build

But when I try to run it using

./gradlew :metadata-service:war:run

The build is getting stuck at 99%. Below is the last few lines of logs

Can anyone help me resolve this?

Seem to be related to auth. @big-carpet-38439, any idea what's happening here?

@helpful-optician-78938 @big-carpet-38439 Does this help?

Is your DB running and configured to the correct URL? Looks like it is failing to create the connection to the DB during start up.

I didn't explicitly run anything except for

./gradlew build
./gradlew run

Build is successful but run is again stuck at the same issue above Tried running the GMS with below commands and got the above error

./gradlew :metadata-service:war:build
./gradlew :metadata-service:war:run

Are you attempting to run GMS without starting up other Docker images? GMS requires a backend database and other services to start up.

Thanks for the clarification, it's resolved now
