[cloud-app-engine-springboot] Deploy a Spring Boot app to App Engine standard environment step code is outdated:

[porturabo]

Hi team, looks like the code for the step 3 is outdated:

 curl https://start.spring.io/starter.tgz \
  -d bootVersion=3.0.5 \
  -d dependencies=web \
  -d type=maven-project \
  -d baseDir=gae-standard-example | tar -xzvf -

will throw an error, while the version updated 3.3.11 will work fine. Here is my working example:

curl -X POST https://start.spring.io/starter.tgz \
                                                            -d bootVersion=3.3.11 \
                                                            -d dependencies=web \
                                                            -d type=maven-project \
                                                            -d baseDir=gae-standard-example | tar -xzvf -
