This commit replaces Spring Boot's basic dependency management support
with separate dependency management plugin. This has a number of
benefits including:
1. A Maven bom can be used rather than a custom properties file
2. Dependency management is applied transitively rather than only to
direct dependencies
3. Exclusions are applied as they would be in Maven
4. Gradle-generated poms are automatically configured with the
appropriate dependency management
Closes gh-2133
Update all starter POMs to remove commons-logging dependencies that are
not longer required when using the Spring Boot Gradle plugin.
Mainly reverts code from 196f92bd42
See gh-1047
Due to the lack of dependency management in Gradle a number of the
starters were pulling in old versions of spring-tx (and in some cases
spring-context-support as well) as the only dependency was a
transitive one that pulled in an older version.
This commit adds explicit dependencies on spring-context-support and
spring-tx where appropriate. These dependencies will specify Boot's
preferred version of Spring causing Gradle to do the right thing as it
prefers the latest version of a dependency when there is more than one
to choose from.
Fixes#1028
Gradle hasn’t different exclusion semantics to Maven. In Maven you can
exclude spring-core’s commons-logging dependency once and it’ll be
honoured even if you have multiple transitive routes to commons-logging
via spring-core. In Gradle you have to exclude commons-logging from
everything that has a transitive spring-core dependency. To make matters
worse this doesn’t only apply to dependencies and exclusions declared in
build.gradle but also to dependencies and exclusions declared in the pom
files of the artifacts that a Gradle build depends upon.
In short, to make our starters work as intended with Gradle, this commit
adds many, many exclusions for commons-logging. It also removes
commons-logging exclusions from spring-boot-dependencies’
<dependencyManagement> as they have no effect with Gradle and their
presence can cause us to miss required exclusions in a starter
Fixes#987
Update all relevant starter POMs to include a `spring-core` dependency
with an exclusion on `commons-logging`. This prevents `commons-logging`
and `jcl-over-slf4j` from both being on the classpath.
Also add enforcer rules to ensure that commons-logging doesn't sneak
back in, and that there is no dependency convergence. (some additional
libraries were required in spring-boot-dependencies)
Tested with a sample maven project as well as using the `spring jar`
command.
Fixes gh-985
This commit harmonizes the dependency management of internal modules
so that versions can be omitted everywhere. Update the maven coordinates
to provide the full groupId for consistency
The dependencies pom.xml now declares an import to the spring-data-releasetrain BOM pom.xml which in turn constraints version numbers for a dedicated release train release. This has the effect of users being able to upgrade to a certain release train by redeclaring the spring-data-releasetrain.version property to e.g. Dijkstra-M1. Individual modules can be upgraded by simply declaring the dependency in the desired version manually in a <dependencies /> or <dependencyManagement /> block.
Removed the explicit declaration for Spring HATEOAS as it is pulled in transitively by Spring Data REST anyway and thus makes sure it's in a compatible version.
