Conflicting HelpMojo error when executing mvn test #123

Closed goneall closed 1 year ago

goneall commented 1 year ago

When executing mvn test on the latest code, I'm getting the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-plugin-plugin:3.9.0:descriptor (default-descriptor) on project spdx-maven-plugin: Error extracting plugin descriptor: 'Goal: help already exists in the plugin descriptor for prefix: spdx
[ERROR] Existing implementation is: org.spdx.spdx_maven_plugin.HelpMojo
[ERROR] Conflicting implementation is: org.spdx.maven.HelpMojo'

Maven version is 3.6.3

Attached is the full Maven output with the -X option: mvnoutput.txt

@hboutemy - any ideas? I did a quick look through the pom file and code and didn't see any obvious conflicts.

hboutemy commented 1 year ago

I can't reproduce. I suppose it's a conflict between an old run with older maven-plugin-plugin and current run with latest 3.9.0 (that has changed help mojo generation strategy) just doing a mvn clean should solve the issue (notice: JDK 13 is deprecated, please upgrade to 17 or 21 or downgrade to 11)

Thanks @hboutemy for looking into it. I'm glad it's just me ;). I also suspect this is something in my local environment since the Github action runs successfully.

I did a clean and upgraded to JDK 17 - same problem. I'm thinking I should just wipe out my local maven repo and re-download all the dependencies and plugins and see if that fixes it.

Cleaned up the development environment - it's now working.

Closing the issue.
