Re: [m2e-users] m2e is supposed to use proxy configuration from settings

[Matthew Piggott <mpiggott@xxxxxxxxxxxx>]

I haven't been an committer on the project in a few years so I can't really answer whether the project would be willing to accept the changeset. Eclipse does provide a service to get the proxy information (though I did run into an instance recently where a customer was using some Eclipse setup where the service was not available), I'm not sure how difficult it would be to use that across all the points that would affect maven.

Its obviously also not going to help you if you decide to do a CLI build.

Hi,

Should I send this question to the m2dev group instead? I am warming up to suggesting that this feature is added back to the m2e preferences. We could even contribute the patch.

Basic idea: in some environments it is really difficult for a user to discover their proxy settings. It would be of great advantage to us, and anyone else working in an Enterprise environment, if m2e could be configured to use the Network Connection proxy settings if this is possible.

• The default should be to use whatever is defined in the global or user maven settings. If nothing is defined then - no proxy for m2e either.
  
• But it should be possible to override this default simply by selecting "Use Eclipse proxy settings? (Overrides Maven proxy settings if set)" or similar.

Hence my question about whether it is technically possible to obtain the proxy settings inside Eclipse code so that these could be fed to Maven during a build - particularly when these settings come from the Native provider, which means they might be derived from a complex script of some sort.

In most Enterprise environments a lack of proxy settings means Maven builds fail. Our product relies on Maven to function. So when Maven fails our product fails, and when this happens during an evaluation many users simply give up. In other words, this really matters to us. And I am sure it matters to other Enterprise m2e users out there as well.

Hi Matthew,

Thanks for explaining. 

Is it technically possible to discover and use Eclipse proxy settings for Maven builds executed from m2e - particularly when the Native active provider is available and selected in Network Connection settings?

It was done so the Eclipse build would be consistent with the CLI Maven build.

Hi,

According to this message "m2e is supposed to use proxy configuration from settings.xml only". Could someone please explain, or point me at, the reasoning behind this?

Why do I ask?

We are deploying our RCP app to Enterprise environments where the standard is to use Native proxy settings in Eclipse. So the user is not aware of details of their proxy server and helping them to find this information can be a pain in the neck. 

In this context it would be highly desirable for m2e to use the common Eclipse proxy settings if these are set. I can understand why this might not be everyone's default choice, so how about adding a preference? "Use Eclipse Proxy settings? [Checkbox]" (off by default).
