Bamboo: maven-resources-plugin:2.6 or one of its dependencies could not be resolved

[Aditya]

Hi Everyone

I am trying to build a sample java image using bamboo via a dockerfile. But I'm getting this error. We have added the proxy settings in settings.xml ~/.m2 folder.

It looks like a clear proxy related issue. As aforementioned, we have already proxy related information in ~/.m2 folder. Is there something needs to be done on bamboo level which i am forgetting? 

Please help me out as I really need to crack this asap. 

PS: I am testing this out inside a corporate network, and we are behind a proxy. I am getting a value of 200 OK when I tried to telnet central maven repo.

I have the same problem. Did you solved it ?

Hi @xing chen

I guess you are also behind a corporate network. This was clearly a proxy permission related error.

Our organization has set rules such that Maven cannot contact remote maven repo to resolve external dependencies (such as JUnit, etc) which are used in a project. 

So we switched our build tool to Apache Ant, and builds are happening without a hitch. 

We are trying to improve our build structure by leveraging Apache Ivy + Sonatype Nexus. 

I hope this helps.

Regards

Aditya
