leiningen, lein, clojure build behind proxy server with lein_tool_deps plugin

I am new to clojure and I am trying to build a porject on a system that is behind a proxy server.
Every lein command I run tries to fetch middleware dependencies using the :middleware [lein-tools-deps.plugin/resolve-dependencies-with-deps-edn] tool. However, whenever it tries to download depedencies stated within the deps.edn file Java throws a connection timeout while trying to connect to https://repo1.maven.org/maven2/
environment variables
http_proxy
https_proxy
no_proxy
are configured properly.
I configured /home/<user>/.m2/settings.xml to use the proxy as well
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<proxies>
<proxy>
<id>my-proxy</id>
<active>true</active>
<protocol>http</protocol>
<host>myproxy.....</host>
<port>XXXX</port>
<nonProxyHosts>...|*.my.domain|localhost|127.0.0.1</nonProxyHosts>
</proxy>
</proxies>
</settings>
deps.edn is
{:deps {org.clojure/clojure {:mvn/version "1.10.0"}
org.clojure/clojurescript {:mvn/version "1.10.516}
.... }
:paths ["src/cljs" "resources" "target"]
:aliases {:build {:main-opts ["-m" "figwheel.main" "-b" "dev" "-r"]}}}
Any lein command (ex: lein deps) results in Could not transfer artifact org.clojure:clojure:pom:1.10.0 from/to central (https://repo1.maven.org/maven2/): connect timed out
However, removing :middleware from the file project.clj allows me to fetch any dependency not in defined in the plugin.
How can I get the plugin to use the http proxy?

Unable to deploy maven artifact to maven central repository using travis

I am trying to deploy maven artifact to central repository through Travis but I am facing below error:
[ERROR] Failed to execute goal org.sonatype.plugins:nexus-staging-maven-plugin:1.6.7:deploy (injected-nexus-deploy) on project Test-plugin: Execution injected-nexus-deploy of goal org.sonatype.plugins:nexus-staging-maven-plugin:1.6.7:deploy failed: Nexus connection problem to URL [https://oss.sonatype.org/ ]: 401 - Unauthorized -> [Help 1]
I have set correct username and password for sonatype account, still I am getting the same error.
Below are the files uploaded:

Looks like your settings.xml in the .m2 folder in your home directory is not having proper authorization properties set for maven to look
I am enclosing a sample XML for your reference ..

Here is the troubleshooting guide if you are getting 404
https://support.sonatype.com/hc/en-us/articles/213464518-Troubleshooting-Artifact-Download-Failures
From the docs
SNAPSHOT look-ups, or version ranges, or unversioned dependencies (typically plugins) will trigger metadata look-up. If the version referenced by the maven-metadata.xml is not there you will get a 404.
This can usually be fixed by running rebuild metadata on the affected artifact.

I have installed maven 3.2.3 and i tried to import one project to eclipse. I got this error [duplicate]

Maven is not able download the required artifacts. Check the proxy settings in your maven settings.xml. If you are using a proxy, provide the corresponding host and port details below.
<proxies>
<proxy>
<id>myproxy</id>
<active>true</active>
<protocol>http</protocol>

You need to get ssl certificate of maven repo server and copy that into your local jre/lib/security folder.
Steps:
1. Download this Java program https://confluence.atlassian.com/download/attachments/180292346/InstallCert.java
Compile
Run with command line parameter maven repo server
Copy the generated ssl to your local JRE/lib/security
For detailed steps pl follow this post:

any help? tnx.

I faced this issue when my proxy server was not configured correctly for maven. You should check with your network administrator about proxy server and add the it in settings.xml under conf dir.
You can look for <proxies> tag and update the fields.
When I face this issue, I too felt it happened for just a few jars, but then all other required jar files were already present in my local repository and hence I was getting it for a few jars only.

I had this error trying to deploy to an internal instance of Nexus with a Maven client that was using proxies with no settings. Attempting to access a Nexus instance on the LAN via a proxy resulted in the Not authorized, ReasonPhrase:Unauthorized error.
<nonProxyHosts>internal.hostname</nonProxyHosts> fixed the issue.

Please check access of repository or password which had given in settings.xml

Adding this in case it helps someone else. In my case I was receiving this error and none of the solutions I found seemed to help. In the end I needed to add the config option to settings.xml to set interactiveMode to false.

If you are sure that your mirror links are configured properly in the settings.xml file, then please try this:
Navigate to .m2 -> repositories
Search for "lastupdated"
Delete all the files that come in the search result.
Then do a 'mvn clean install' -> new 'lastupdated' files would be created.

Try to changes groupId for the dependencies which you have added.
It work
