The issue was caused from using the deprecated google maven plugin com.google.appengine.appengine-maven-plugin which fails silently and it does not update GAE configuration, and so the defaults ones are used, for example the instance class was F1 .

Switched to maven plugin com.google.cloud.tools.appengine-maven-plugin .切换到 maven 插件com.google.cloud.tools.appengine-maven-plugin 。
