SpringBoot Reproducible build for spring-boot-maven-plugin:build-info

In order to make maven build will be reproducible we use property project.build.outputTimestamp in maven project.

So spring-boot-maven-plugin:build-info should take this value as default to not break reproducible build.

Most of maven plugins takes into account this property.

Both build info's time and project.build.outputTimestamp support ISO-8601 formatted input so this is already supported by setting time using the value of project.build.outputTimestamp:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <executions>
        <execution>
            <goals>
                <goal>build-info</goal>
            </goals>
            <configuration>
                <time>${project.build.outputTimestamp}</time>
            </configuration>
        </execution>
    </executions>
</plugin>

The risk of changing the default behaviour is pretty small, but, given that it's already possible with minimal additional configuration, I do wonder if we should consider this to be an enhancement and implement it in 2.6.

It is ok for me, that you scheduled change for 2.6 version. Can I do something before merge?

Comment From: wilkinsona

@slawekjaranowski No, nothing for you to do, thank you. We'll aim to merge this for inclusion in 2.6.0-M1 once we've released 2.5.0 and created the 2.5.x maintenance branch.
