Subject [jira] [Commented] (MCHECKSTYLE-42) checkstyle does not take into account proxy settings from settings.xml
Date Wed, 30 Sep 2015 20:06:05 GMT

    [ https://issues.apache.org/jira/browse/MCHECKSTYLE-42?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14938772#comment-14938772
] 

Michael Osipov commented on MCHECKSTYLE-42:
-------------------------------------------

Still applies. The problem is that this plugin uses the Plexus {{ResourceManager}} which in
turn handles all HTTP calls to {{URLResourceLoader}}. This uses plain {{HttpUrlConnection}}
which does not have proxy setttings provided. [Here|https://github.com/sonatype/plexus-resources]
is the GitHub project.

> I've been hesitating wether to report it as bug or as improvement, but at the moment
I'd rate it as a bug.
> It took me quite some time to figure out why this was going wrong.
> In my {{settings.xml}} I've defined our company proxysettings. These settings are used
by Maven when connecting to the remote repository.
> However when using the checkstyle plugin as part of the site generation I can  not obtain
our {{checkstyle.xml}} which is available via http.
> I found a solution by adding the following parameters on the command line when continuum
launches maven:
> {{-Dhttp.proxyHost=myproxy -Dhttp.proxyPort=80}}
> Wouldn't it be possible for the maven checkstyle plugin to use the settings defined in
{{settings.xml}}, so I've only to define those once?
