Support for Bill Of Materials #59
Description
Summary
Maven supports the idea of a Bill of Materials (BOMs) that hold versions for dependencies.
For example:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>io.vertx</groupId>
<artifactId>vertx-stack-depchain</artifactId>
<version>${vertx.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>Then dependencies can be declared without version:
<dependency>
<groupId>io.vertx</groupId>
<artifactId>vertx-core</artifactId>
</dependency>
<dependency> <!--Optional dependency of vertx-core-->
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
</dependency>This allows for upgrading the dependencies in the BOM all at once with a single version change of the BOM.
Proposal
Add support for BOMs in bld
For example:
public class BldProjectBuild extends Project {
public BldProjectBuild() {
pkg = "com.example";
name = "example";
mainClass = "com.example.Main";
version = version(0, 1, 0);
javaRelease = 21;
repositories = List.of(MAVEN_CENTRAL, RIFE2_RELEASES);
BillOfMaterials bom = BillOfMaterials.of("io.vertx", "vertx-stack-depchain", version(4, 5, 12));
scope(compile)
.include(dependency("io.vertx", "vertx-core", bom))
.include(dependency("com.fasterxml.jackson.core", "jackson-databind", bom));
}
public static void main(String[] args) {
new BldProjectBuild().start(args);
}
}Of course, this is just an example, maybe there is better syntax for this or maybe there is a better approach altogether. Please let me know what you think.
