Org.apache.commons.lang is internal and is not available for export

[DougBass]

I’m porting my plugin to Confluence 9.0 and I get this error on load. As suggested I did the command:

atlas-mvn dependency:tree -Dincludes=org.apache.commons:commons-lang

And the result is: [INFO] — dependency:3.7.0:tree (default-cli) @ ccac —

I think this means that this dependency is not included in my build. So why is the “internal” error displayed on load?

Btw my pom is:

I don’t totally understand the question, but isn’t this true that P7 requires you to use “lang3” instead of “lang”?

Hello, we are currently facing an OSGI-related issue (similar to this) with our Jira v10.0.1 instance while developing a plugin. On previous JIRA versions it worked fine.

error:
Caused by: org.osgi.framework.BundleException: Unable to resolve com.sykorait.jira.plugins.USU-Service-Management-Connector [277](R 277.0): missing requirement [com.sykorait.jira.plugins.USU-Service-Management-Connector [277](R 277.0)] osgi.wiring.package; (osgi.wiring.package=org.apache.commons.lang) Unresolved requirements: [[com.sykorait.jira.plugins.USU-Service-Management-Connector [277](R 277.0)] osgi.wiring.package; (osgi.wiring.package=org.apache.commons.lang)]

In our plugin pom.xml, we have included the following dependency:

 <dependency>
      <groupId>org.apache.commons</groupId>
      <artifactId>commons-lang3</artifactId>
      <scope>compile</scope> 
      <!-- tried "provided" also -->
      <version>3.17.0</version>
</dependency>

and upon inspecting the OSGI browser, we can see that this package (org.apache.commons.lang, lang3) is indeed provided by the “System Bundle”.

Has anyone else faced this issue with OSGI package resolution in the newer Jira version? Would appreciate any guidance or suggestions for resolving this.

Thanks in advance!

Exports from the system bundle are no longer all available to apps, this change came in with Platform 7 and restrictions on “Grey APIs”

A package can be exported by the system bundle, but unavailable for import in apps, this is intentional with Platform 7.

When this happens, you’ll see a warning in the logs telling you.

I recommend reading the hundreds of replies in the threads relating to platform 7, which should get you up to speed.

For dependencies no longer available for import from the platform, you must bundle them within your app, using compile scope. Commons Lang 3 might be exported for apps, this is something you’d need to verify, and then swap usage if so.

Platform 7 upgrade in progress: Learn about the first highlights and changes

Hi Developer Community , We recognize there is a lack of clarity around some of the changes that will be shipped as part of future Atlassian Data Center products. In this post, we want to go into more detail on some of the changes that are shipped as part of Platform 7 and let you know what our next steps are to address the concerns brought up across several communication channels. The Platform acts as a baseline of common libraries and plugins that are used across all products. Products…

Preparing for Jira Software 10.0 and Jira Service Management 6.0 - multiple EAPs coming your way

We are excited to share our plans for the upcoming JSW 10.0/JSM 6.0 Data Center platform release. As a reminder, a platform release often includes multiple breaking changes that establish the foundation for continued improvement in future 10.x/6.x feature releases. JSW 10.0/JSM 6.0 primarily aim to reduce the number of exposed dependencies, enabling a timely and efficient resolution of security issues. Additionally, it involves upgrading the JSW & JSM technology stack by uplifting dependencies …

Apps still using the old school <component> XML configuration will also have OSGi issues on Platform 7. Usually you need to port the app to use either Spring Scanner, or Spring Java Configuration.

You’ll see some commentary on this in the linked threads.

I found the solution!!

I added this dependency to my pom:

<dependency>
      <groupId>org.apache.commons</groupId>
      <artifactId>commons-lang</artifactId>
      <version>2.1</version>
      <scope>compile</scope>
    </dependency>

And to the <import-package> section I added this:

org.apache.commons.lang.*;resolution:="optional",
