Can a Maven BOM(BOM1) contain another BOM(BOM2) in its dependencyManagement? If yes, how could the usage of BOM1 through inclusion in a pom.xml can use the dependencies from BOM2 in a project? Thanks in advance! To better explain the situation, the below works when i include both of the in the pom.xml of the service:

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring-boot-dependencies.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>my.custom.bom</groupId>
                <artifactId>my.custom.bom</artifactId>
                <version>${my.custom.bom.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
</dependencyManagement>

Whereas the following does notwhen I include it in the pom.xml of the service:

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>my.custom.bom</groupId>
                <artifactId>my.custom.bom</artifactId>
                <version>${my.custom.bom.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
</dependencyManagement>

And the my.custom.bom in the second situation includes the spring-boot-dependencies like so:

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring-boot-dependencies.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
</dependencyManagement>

To summarize when pom.xml includes BOM1 and BOM2 works, but when pom.xml includes BOM1 and BOM1 includes BOM2 no longer works.
