maven 在执行无服务器部署到 aws 时出现构建错误（com.amazonaws:aws-lambda-java-events:Z68995FCBF432492D15484D04A9D2AC4 的“dependencies.dependency.version”缺失）

Question

I have a serverless aws / java project (simple hello world type).

I can compile and build the application fine, but when I do a 'Deploy Serverless Application' on my template.yaml using IntelliJ IDE, I get a maven build error:

 Build Failed Error: JavaMavenWorkflow:MavenBuild - Maven Failed: [INFO] Scanning for projects... [ERROR] [ERROR] Some problems were encountered while processing the POMs: [ERROR] 'dependencies.dependency.version' for com.amazonaws:aws-lambda-java-events:jar is missing. @ line 46, column 21 [ERROR] 'dependencies.dependency.version' for com.amazonaws:aws-java- sdk:jar is missing. @ line 52, column 21

My pom.xml is as follows for those two dependencies. I also use DependencyManagement:

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>com.amazonaws</groupId>
                <artifactId>aws-java-sdk-bom</artifactId>
                <version>1.11.651</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

        <dependency>
            <groupId>com.amazonaws</groupId>
            <artifactId>aws-lambda-java-events</artifactId>
    </dependency>
        <dependency>
            <groupId>com.amazonaws</groupId>
            <artifactId>aws-java-sdk</artifactId>
    </dependency>

I could revert to using < version > tags again but then the rest of my application won't build due to the other dependencies I have. Also, I find using aws-java-sdk-bom a clean way of managing dependencies without needing to worry about versions and compatibility.

Answer 1

Checking on the pom.xml file of aws-jafa-sdk-bom on https://github.com/aws/aws-sdk-java/blob/master/aws-java-sdk-bom/pom.xml

The dependencies "aws-lambda-java-events" and "aws-java-sdk" are not defined.

You should add the version number, for example:

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-lambda-java-events</artifactId>
    <version>2.2.7</version>
</dependency>

Also, I haven't seen "aws-java-sdk" as a dependency anywhere.
