DJL - Bill of Materials (BOM)¶

BOM stands for Bill Of Materials. Maven lets us define the versions of the dependencies or transitive dependencies in a separate POM. A BOM package is a POM only jar file that is used to control the versions of a project’s dependencies and provide a central place to define and update those versions. See Maven document about how BOM works.

DJL's BOM package provides a flexibility way for developers to add DJL dependencies to their project without worrying about each modules' version that we should depend on.

How to use DJL's BOM¶

Use BOM in Maven¶

First you need add BOM into your pom.xml file in section (notice that you will need to mention the type as pom and the scope as import) as the following:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>ai.djl</groupId>
            <artifactId>bom</artifactId>
            <version>0.31.0</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

Then you import the desired DJL modules into to you pom.xml file (no version is needed):

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>ai.djl</groupId>
            <artifactId>bom</artifactId>
            <version>0.31.0</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
<dependencies>
    <dependency>
        <groupId>ai.djl</groupId>
        <artifactId>api</artifactId>
    </dependency>
    <dependency>
        <groupId>ai.djl.mxnet</groupId>
        <artifactId>mxnet-engine</artifactId>
    </dependency>
    <dependency>
        <groupId>ai.djl.mxnet</groupId>
        <artifactId>mxnet-engine</artifactId>
    </dependency>
</dependencies>

Use BOM in Gradle¶

First you need add BOM into your build.gradle file as the following:

    implementation platform("ai.djl:bom:0.31.0")

Then you import the desired DJL modules into to you pom.xml file (no version is needed):

    implementation "ai.djl.pytorch:pytorch-model-zoo" // No version required
