Setting socks5 proxy for maven using settings.xml doesn't take effect.
Hi,
I'm using Ubuntu 20.04 and installed maven using ` sudo apt-get
install maven `. Now, I want to set socks5 proxy for maven. When I set
it via environment variable liek this:
export MAVEN_OPTS="-DsocksProxyHost=127.0.0.1 -DsocksProxyPort=18887"
It can work smoothly.
But if I set it by using ` ~/.m2/setting.xml ', the socks5 proxy
cannot be used at all. The content of the setting.xml file is as
following:
<proxies>
<proxy>
<id>ss</id>
<active>true</active>
<protocol>socks5</protocol>
<username></username>
<password></password>
<host>127.0.0.1</host>
<port>18887</port>
<nonProxyHosts>127.0.0.1</nonProxyHosts>
</proxy>
</proxies>
What's wrong with my settings or usages?
Regards

I've installed the latest version from maven official website and set
the PATH to override the system's maven,
so this should be no need for my case. See the following for more info.

Sorry for above descriptions, in fact, I use the pre-compiled package
supplied by maven official website here:
https://apachemirror.sg.wuchna.com/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz
See the following for more information:
$ which mvn
/opt/apache-maven/3.6.3/bin/mvn

It seems I'm wrong. Even with the above enviroment variable, I still
see the following info:
$ mvn -X clean install | grep 'Using connector BasicRepositoryConnector'
[DEBUG] Using connector BasicRepositoryConnector with priority 0.0 for
https://repo.maven.apache.org/maven2
^C
Obviously, there are no proxy activated for the connection.
In the previously postings, due that there are so many packages have
already been downloaded into the local repository here:
~/.m2/repository/, which makes the maven compile procedure so fast and
doesn't need to download them from the remote repository. As a result,
I simply think that it's the socks5 proxy that speed up the remote
packages downloading progress.

Got it, thanks for your clarification.

Sorry for my typo in the above command. It should be tested as follows:
$ mvn -X clean install "-Dhttp.proxyHost=127.0.0.1
-Dhttp.proxyPort=8080" | grep 'Using connector
BasicRepositoryConnector'

Greping in the maven installation directory also confirms the above comment:
$ grep -inR 'MAVEN_OPTS' . | grep -i java
./3.6.3/bin/mvnDebug:26:# MAVEN_OPTS (Optional) Java runtime
options used when Maven is executed.

Seems you are right. I confirmed the socks5 proxy is in effect by the
following methods:
First start a tcpdump process for capture the packages on the socks5
proxy port, say tor used here:
$ sudo tcpdump -i lo 'port 9050'
Then running the maven with the following methods:
# Prevent maven from using the locally cached packages:
$ rm -fr ~/.m2/repository/
$ export MAVEN_OPTS="-DsocksProxyHost=127.0.0.1 -DsocksProxyPort=9050"
$ mvn -X clean install
or using the following one-line command:
$ mvn -X clean install -DsocksProxyHost=127.0.0.1 -DsocksProxyPort=9050
In both cases, there will be many packages captured by tcpdump on tor
port 9050 once maven downloads from remote repository.

Just guessing.
The -D options you use are intended and consumed by JVM itself.
That's why socks proxy works when configured with
socksProxyHost/socksProxyPort, because maven even doesn't know about
traffic being proxied.

Thanks for your explanations. But I still have some confusions on the
proxy usage. See my following testings.
All the following testings are using the xdm which is a maven project,
see here for more info:
https://github.com/subhra74/xdm#building-from-source
The following steps for based on the instructions here:
https://www.baeldung.com/maven-behind-proxy
1. For the settings.xml based proxy setting, I can confirm maven works
via the http proxy set by me in the file ~/.m2/settings.xml.save which
has the following content:
<settings>
<proxies>
<proxy>
<id>ss</id>
<active>true</active>
<protocol>http</protocol>
<host>127.0.0.1</host>
<port>8080</port>
<nonProxyHosts>localhost|127.*|[::1]</nonProxyHosts>
</proxy>
</proxies>
</settings>
Then the following confirms that the proxy is works:
$ mvn -s ~/.m2/settings.xml.save -X clean install | grep 'Using
connector BasicRepositoryConnector'
[DEBUG] Using connector BasicRepositoryConnector with priority 0.0 for
https://repo.maven.apache.org/maven2 via 127.0.0.1:8080
2. Then I try to use the environment variable based method to set the
proxy but failed to confirm it. See the following for more info:
Use the proxy setting directly in maven's command options:
$ mvn -X clean install -D"http.proxyHost=127.0.0.1
-Dhttp.proxyPort=8080 -Dhttp.nonProxyHosts=localhost|127.0.0.1" | grep
'Using connector BasicRepositoryConnector'
[DEBUG] Using connector BasicRepositoryConnector with priority 0.0 for
https://repo.maven.apache.org/maven2
Or define them in the MAVEN_OPTS environment variable:
$ export MAVEN_OPTS="-DhttpProxyHost=127.0.0.1 -DhttpProxyPort=8080"
$ mvn -X clean install | grep 'Using connector BasicRepositoryConnector'
[DEBUG] Using connector BasicRepositoryConnector with priority 0.0 for
https://repo.maven.apache.org/maven2
As you can see, in this case, it seems the http proxy passed as
command options or set by environment variable doesn't picked up by
maven at all. Any hints for this problem?

If you want to use HTTP transport (Resolver/Wagon) via Socks 5 proxy, it
will not work because Apche HttpClient does not support Socks5 proxies
with our setup.
