Spring Boot build in Draft fails because of missing .git folder

[mrumpf]

Many Spring Boot applications use the git-commit-id Maven plugin to read some information (e.g. revision) from the Git repository and later display it under the Spring Boot Actuator endpoint /info.

This fails with the current Draft Java pack because the Git repository is not available in the Docker container.

                    <!-- Spring Boot Actuator displays build-related information if a META-INF/build-info.properties file is present -->
                    <plugin>
                        <groupId>pl.project13.maven</groupId>

                                    <goal>revision</goal>
                                </goals>
                            </execution>

                        </configuration>
                    </plugin>

I hit this too. I had to remove .git from the .dockerignore file so it's available as part of Docker context
