Hi All,

I have created AEM a cloud project using below archtype

mvn -B archetype:generate -D archetypeGroupId=com.adobe.aem -D archetypeArtifactId=aem-project-archetype -D archetypeVersion=30 -D appTitle="Digital Site" -D appId="digitalsite" -D artifactId="aem-digital" -D groupId="com.digital" -D aemVersion=cloud -D includeDispatcherConfig="y"

I have added some project specific dependency

		<dependency>
			<groupId>com.fasterxml.jackson.dataformat</groupId>
			<artifactId>jackson-dataformat-csv</artifactId>
			<version>2.11.4</version>
		</dependency>

But while building the project I am getting error

[WARNING] The analyser found the following warnings for author and publish :
[WARNING] [artifact-rules] artifact-rules: Artifact rules are not specified, unable to validate feature
[ERROR] The analyser found the following errors for author and publish :
[ERROR] [api-regions-exportsimports] com.digital:aem-digital.core:1.0.0-SNAPSHOT: Bundle aem-digital.core:1.0.0-SNAPSHOT is importing package(s) com.fasterxml.jackson.dataformat.csv in start level 20 but no bundle is exporting these for that start level. (com.digital:aem-digital.all:1.0.0-SNAPSHOT)

Can please help me here How I can resolve this error??

This is because of the aemanalyser-maven-plugin that gets executed in all module of the project which run the same checks locally as in the Cloud Manager deployment pipeline.

More about the plugin : https://github.com/adobe/aemanalyser-maven-plugin/blob/main/aemanalyser-maven-plugin/README.md

For the reported analyzer error,

you can try to follow the step 2 in this blog - https://myaemlearnings.blogspot.com/2021/08/embedding-third-party-dependencyosgi.html
jackson-dataformat-csv artifact is not available OOTB as a bundle in SDK instance or no other packages exports the same. Hence the error while executing this analyzer - api-regions-exportsimports

if you just add the dependency to the pom, this additional JAR is used while compilation and test. But it is not included into the runtime, and therefor this validation process fails.

You either need to embed this dependency into your own bundle, or you find an OSGI-version of that bundle and deploy it along with your core bundle.

Jörg_Hoh I have tried to add below in core pom.xml but still getting same error.

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <version>4.2.1</version>
    <extensions>true</extensions>
    <configuration>
        <instructions>
            <Export-Package>com.fasterxml.jackson.*</Export-Package>
            <Embed-Dependency>jackson-dataformat-csv;scope=compile|runtime</Embed-Dependency>
            <Embed-Transitive>true</Embed-Transitive>
            <Import-Package>
                com.fasterxml.jackson.*
            </Import-Package>
        </instructions>
    </configuration>
</plugin>

I would drop the Export-Package, because you don't want to re-export any jackson package. The Embed-Dependency looks ok, although you can probably omit the scope statement.

Can you check if the jackson-dataformat.csv jar is placed within the target/classes folder after the build?

Add the dependency to your core bundle and that should clean this error.

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-csv</artifactId>
</dependency>

I tried it too and the build is successful.

@b_sravan I have already added dependency in main pom as well as in core pom gettig error while running below build command

mvn clean install -PautoInstallPackage

Main pom.

		<dependency>
			<groupId>com.fasterxml.jackson.dataformat</groupId>
			<artifactId>jackson-dataformat-csv</artifactId>
			<version>2.11.4</version>
		</dependency>

Core pom

            <dependency>
                <groupId>com.fasterxml.jackson.dataformat</groupId>
                <artifactId>jackson-dataformat-csv</artifactId>
            </dependency>

Hi,

This error type means

Checks if all OSGI bundles have their Import-Package declarations satisfied by the Export-package declaration of other included bundles in the Maven project. An error would look like this:

[ERROR] org.acme:mybundle:0.0.1-SNAPSHOT: Bundle org.acme:mybundle:0.0.1-SNAPSHOT is importing package(s) org.acme.foo in start level 20 but no bundle is exporting these for that start level.

To troubleshoot, see if the bundle providing the package is included in the deployment, or alternatively look at the manifest of the bundle that you would expect to be exporting to determine if the wrong name or wrong version was used.

@arunpatidar I am getting this just after adding below dependency which I am using on servlet class. And I am getting this error even run mvn clean install

I'm having this same issue, but for "internal" dependencies. We have a multi-tenant project setup like below:

project-root

all - embeds parent.all.zip, tenant-a.all.zip, tenant-b.all.zip
parent (shared Java and HTL)

all - embeds parent.core.jar, parent.ui.apps.zip, parent.ui.config.zip, parent.ui.content.zip
core
ui.apps
ui.apps.structure
ui.config
ui.content

tenant-a

all - embeds tenant-a.core.jar, tenant-a.ui.apps.zip, tenant-a.ui.config.zip, tenant-a.ui.content.zip
core - has dependency for parent.core
ui.apps
ui.apps.structure
ui.config
ui.content
ui.frontend

tenant-b

all - embeds tenant-b.core.jar, tenant-b.ui.apps.zip, tenant-b.ui.config.zip, tenant-b.ui.content.zip
core - has dependency for parent.core
ui.apps
ui.apps.structure
ui.config
ui.content
ui.frontend

dispatcher

my "tenant-#.all" modules are failing during aem-analyser because their embeded "tenant-#.core" jars are importing packages from "parent.core", but no bundles are exporting those packages...

[ERROR] [api-regions-exportsimports] com.project.namespace:tenant-a.core:1.0.0-SNAPSHOT: Bundle tenant-a.core:1.0.0-SNAPSHOT is importing package(s) [com.project.namespace.parent.core.models, com.project.namespace.parent.core.models.marketo] in start level 20 but no bundle is exporting these for that start level. (com.project.namespace:tenant-a.all:1.0.0-SNAPSHOT)

Previously, I had parent.all.zip defined as an embed in my tenant-#.all packages like:

<embedded>
    <groupId>com.project.namespace</groupId>
    <artifactId>parent.all</artifactId>
    <type>zip</type>
    <target>/apps/parent-packages/container/install</target>
</embedded>

Which allowed my build to pass and deployed functionality worked fine, however it caused a "PackageOverlaps" bug in our Adobe CM pipeline scans, which is what I'm trying to resolve now.

I have confirmed that the parent.core bundle manifest is exporting the required packages, so I don't understand why tenant-#.all analysis is failing for tenant-#.core. And yes, the tenant-#.core modules are including parent.core as a dependency.

Maybe I'm approaching this incorrectly, but I am trying to keep the tenant modules from deploying parent modules, since the parent modules are being deployed already (project-root.all -> parent.all -> parent.core). How can I inform aemanalyser in "submodule" that it's dependencies are deployed or are deploying?
