Plugin build error: copy-bundled-dependencies failed

[sarahc]

I know this question has been asked elsewhere, but the accepted answer didn't work for me.

I've been given a Confluence plugin to debug, and I haven't been able to build it. It gives the following error on build:

Execution default-copy-bundled-dependencies of goal com.atlassian.maven.plugins:maven-confluence-plugin:4.1.4:copy-bundled-dependencies failed: An API incompatibility was encountered while executing com.atlassian.maven.plugins:maven-confluence-plugin:4.1.4:copy-bundled-dependencies: java.lang.NoSuchMethodError: org.apache.maven.execution.MavenSession.getRepositorySession()Lorg/sonatype/aether/RepositorySystemSession;

I've seen a lot of resources online saying that it's due to a mismatch of AMPS and Maven versions. However, I've used this AMPS version with my current environment to build other projects (my environment is the following):

ATLAS Version: 8.0.16
ATLAS Home: D:\PROGRA~1\Atlassian\atlassian-sdk-plugin-8.0.16
ATLAS Scripts: D:\PROGRA~1\Atlassian\atlassian-sdk-plugin-8.0.16\bin
ATLAS Maven Home: D:\PROGRA~1\Atlassian\atlassian-sdk-plugin-8.0.16\apache-maven-3.5.4
AMPS Version: 8.0.2

(And my pom.xml file contains the following properties:)

<properties>

  <confluence.data.version>5.5.4</confluence.data.version>

 <baseurl.confluence>http://localhost:${http.confluence.port}/${context.confluence.path}  </baseurl.confluence>    

</properties>

I've tried a bunch of different configurations, and haven't been able to get it to build. I don't really understand Maven black magic well enough to know what's really going wrong and why. If anyone could point me in the right direction, it would be greatly appeciated!

Hi @sarahc,

For plugin development questions you may be better off posting them at the developer community.
