Getting maven build errors when trying to run atlassian plugin

Deleted user April 5, 2018

Hi,

I'm new to Atlassian plugins so I thought I would start by compiling and running the hello world plugin that atlassian provides as a tutorial: https://developer.atlassian.com/server/framework/atlassian-sdk/create-a-helloworld-plugin-project/

 

I have JDK 9 and MVN 3.3 running. I've followed all the instructions on that tutorial, however, I am presented with the following errors and am unable to understand what is going wrong:

[INFO] Error stacktraces are turned on.
[INFO] Scanning for projects...
[WARNING] The POM for com.atlassian.maven.plugins:maven-confluence-plugin:jar:6.3.15 is missing, no dependency information available

@[deleted] Can you tell me the output of this command atlas-version?

 I was able to get past these errors by switching to jdk 1.8 and adding in the maven respository as a plugin repo in the pom file of my project.

Right, the platform now is supported to JDK8. Using JDK9 may cause some weird things

Hello,

I build the project using: atlas-create-confluence-plugin

as well as importing the project into Eclipse from this link(

Adding a custom action to Confluence) 

https://bitbucket.org/atlassian_tutorial/confluence-custom-action-tutorial/get/master.zip?_ga=2.111115909.1233932827.1534180808-30292495.1533050977

 

I am getting the same error:

org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:
[ERROR] Unresolveable build extension: Plugin com.atlassian.maven.plugins:maven-confluence-plugin:6.3.15 or one of its dependencies could not be resolved: Failure to find com.atlassian.maven.plugins:maven-confluence-plugin:jar:6.3.15 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced @
[ERROR] Unknown packaging: atlassian-plugin @ line 19, column 16

I am using Java 8.

Please guide me how to resolve it.
