Cloud Endpoints Frameworks for Java - Running and testing API backends locally not working #922
Description
In which file did you encounter the issue?
Did you change the file? If so, how?
I first tried what was in the doc. But that didn't work and after some googling and finding this issue thread #533, I tried the following:
export ENDPOINTS_SERVICE_NAME=endpointname-api.endpoints.projectid.goog
gcloud config set project projectid
gcloud auth application-default login
mvn clean package
mvn exec:java -DGetSwaggerDoc
gcloud service-management deploy openapi.json
mvn appengine:devserver
Describe the issue
I get the exception below when running mvn appengine:devserver and a 503 when attempting to access http://localhost:8080/_ah/api/explorer or http://localhost:8080/_ah/admin. An important note is that this service is not the default service in the appengine project. Its appengine-web.xml service tag is campaign-service. I'm wondering if the instructions for running api backends locally is different for an appengine service other than default.
