Hey guys,

I am working on AEMaaCS, trying to use acscommons.io.jsonwebtoken in a util located in core project.

In my uitl, I:

import acscommons.io.jsonwebtoken.Jwts;
import acscommons.io.jsonwebtoken.SignatureAlgorithm;

I am following the guide:

https://adobe-consulting-services.github.io/acs-aem-commons/pages/maven.html

In "all" project added:

<dependency>
<groupId>com.adobe.acs</groupId>
<artifactId>acs-aem-commons-content</artifactId>
<version>5.0.6</version>
<classifier>min</classifier>
<type>zip</type>
</dependency>

And

<embedded>
<groupId>com.adobe.acs</groupId>
<artifactId>acs-aem-commons-ui.apps</artifactId>
<type>zip</type>
<target>/apps/app-vendor-packages/application/install</target>
</embedded>
<embedded>
<groupId>com.adobe.acs</groupId>
<artifactId>acs-aem-commons-ui.content</artifactId>
<type>zip</type>
<target>/apps/app-vendor-packages/content/install</target>
</embedded>
<embedded>
<groupId>com.adobe.acs</groupId>
<artifactId>acs-aem-commons-all</artifactId>
<type>zip</type>
<target>/apps/app-vendor-packages/container/install</target>
<filter>true</filter>
<isAllVersionsFilter>true</isAllVersionsFilter>
</embedded>

In "core" project added:

<dependency>
<groupId>com.adobe.acs</groupId>
<artifactId>acs-aem-commons-bundle</artifactId>
<version>5.0.6</version>
<scope>provided</scope>
</dependency>

The project can be built locally, however, once deployed through the pipeline, it failed in Build Images phase, the log shows:

[api-regions-exportsimports] com.xxx:app-project.core:2024.304.1172654.0003818307: Bundle app-project.core:2024.304.1172654.0003818307 is importing package(s) acscommons.io.jsonwebtoken in start level 20 but no bundle is exporting these for that start level.

(com.xxx:app-project.all:2024.304.1172654.0003818307)

 Am I missing something?

Thanks!

Found the solution for my project:

Add the following to all/pom.xml

<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt-api</artifactId>
<version>0.11.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt-impl</artifactId>
<version>0.11.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt-jackson</artifactId>
<version>0.11.2</version>
<scope>provided</scope>
</dependency>

And also:

<embedded>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt-api</artifactId>
<type>jar</type>
<target>/apps/xxx-vendor-packages/application/install</target>
</embedded>
<embedded>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt-impl</artifactId>
<type>jar</type>
<target>/apps/xxx-vendor-packages/application/install</target>
</embedded>
<embedded>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt-jackson</artifactId>
<type>jar</type>
<target>/apps/xxx-vendor-packages/application/install</target>
</embedded>

In core/pom.xml:

<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt-api</artifactId>
<version>0.11.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt-impl</artifactId>
<version>0.11.2</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt-jackson</artifactId>
<version>0.11.2</version>
<scope>runtime</scope>
</dependency>

After all these, it built and worked well.

Thanks guys!

The ACS AEM Commons library doesn't provide a acscommons.io.jsonwebtoken.SignatureAlgorithm class or package. If you're trying to work with JSON Web Tokens (JWTs) in AEM, you might want to use the Java JWT (JSON Web Token) library, also known as JJWT.

 

I don't see it here ; https://javadoc.io/doc/com.adobe.acs/acs-aem-commons-bundle/5.7.0/index.html

 

why don't you use

 

import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
 
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt</artifactId>
<version>0.9.1</version>
</dependency>

Hi I've tried this but jjwt seems to conflict with some libs and will lead to a server-side exception.

Is it possible to reuse:

acscommons.io.jsonwebtoken

acs-aem-commons also using io.jsonwebtoken.Jwts

if you are getting conflicts - it is better to resolve those and use io.jsonwebtoken.Jwts instead of acscommons.io.jsonwebtoken.

I observed acscommons.io.jsonwebtoken has the interface - does not have the implementation

please check it once.

Use jjwt returns the same error:

xxx is importing package(s) io.jsonwebtoken in start level 20 but no bundle is exporting these for that start level.
 
Any suggestions?

can you try explicit Export JAR statement in pom.xml

 

<executions>
<execution>
<id>bnd-process</id>
<goals>
<goal>bnd-process</goal>
</goals>
<configuration>
<bnd>
<![CDATA[
Import-Package: xxx
Export-Package :io.jsonwebtoken.*;target/dependency/jjwt-api-0.11.2.jar,target/dependency/jjwt-gson-0.11.2.jar,target/dependency/jjwt-impl-0.11.2.jar
]]>
</bnd>
</configuration>

</execution>
</executions>

Thanks Suresh,

May I know if this should be added to root pom.xml or core/pom.xml?
