Restore indentation in published spring-boot-dependencies and spring-boot-starter-parent poms

[KingBuzzer]

The POMs in 2.1.4 lost all formatting/indentation which makes them harder to read.

Examples:

2.1.3 is using 4 spaces indentation:
https://search.maven.org/remotecontent?filepath=org/springframework/boot/spring-boot-dependencies/2.1.3.RELEASE/spring-boot-dependencies-2.1.3.RELEASE.pom

2.1.4 is using no indentation
https://search.maven.org/remotecontent?filepath=org/springframework/boot/spring-boot-dependencies/2.1.4.RELEASE/spring-boot-dependencies-2.1.4.RELEASE.pom

No biggie of course :-) Thanks for a great framework!

Thanks for spotting this, it wasn't intentional. The good news is that the indentation is missing in the snapshot repo (for example https://repo.spring.io/snapshot/org/springframework/boot/spring-boot-dependencies/2.1.5.BUILD-SNAPSHOT/spring-boot-dependencies-2.1.5.BUILD-SNAPSHOT.pom), so the indentation is being lost somewhere that should be in our control, rather than on the way to Maven Central.

By the way, i found in <artifactId>spring-boot</artifactId> use 2 spaces to indentation,but in <artifactId>spring-boot-dependencies</artifactId> use 4 spaces to indentation.
Can we use 4 space in all pom files?

@songxinqiang Where did you find this difference?

[wilkinsona]

Curiously, the problem doesn't seem to affect every pom. For example, the pom for spring-boot is fine (https://repo.spring.io/snapshot/org/springframework/boot/spring-boot/2.1.5.BUILD-SNAPSHOT/spring-boot-2.1.5.BUILD-SNAPSHOT.pom).

I think I see what @songxinqiang was getting at. In 2.1.3, spring-boot is indented with 2 spaces but spring-boot-dependencies is indented with 4 spaces. In 2.1.4, spring-boot is still indented with 2 spaces but spring-boot-dependencies is no longer indented.

We have another one of these in spring-boot-starter-parent that currently uses 4.

yeah, I found a different number of indented spaces in different files.
