Error creating Maven depending on dependencies

Question

I have a local artifact repository that my maven settings are pointed to, but for some reason this does not seem to fall into it, and when I try to complete the installation, it fails. I can access the URL directly in my browser and also access the maven repository through the browser. I can also ping both.

Any ideas why he continues to fail? Stack trace below

Greetings

Answer 1

I do not know if you used the maven built-in or external installation (Window-> Preferences → Maven → Installations).

If it is external, you must declare your corporate proxy in settings.xml (in the conf folder of your external installation or in your local repository).

This may be the case if you use the built-in maven. Then you must provide the settings file in Global Preferences for Embedded Installation.

If you are using an external maven installation, you can also try the command line outside of eclipse.

WITH

 mvn -U ... 

You can get maven to search for the latest plugins.

If you are behind a proxy server, you can use

mvn clean install -DproxySet=true -DproxyHost=<your proxy host> -DproxyPort=<port>

Answer 3

If you are using a proxy server and you have unpacked the Maven directory, then update settings.xml in {APACHE_MAVEN_DIR} \ conf , as shown below,

just update the lines "REPLACE ~~" with the appropriate information and try again.

 <proxies> <proxy> <id>example-proxy</id> <active>true</active> <protocol>http</protocol> <host>proxy.example.com</host> <port>8080</port> <username>proxyuser</username> <password>somepassword</password> <nonProxyHosts>www.google.com|*.example.com</nonProxyHosts> </proxy> </proxies> 

Here is the official proxy setup documentation in maven settings.xml:

https://maven.apache.org/guides/mini/guide-proxies.html

Answer 4

Try configuring your eclipse proxy in

Settings -> General -> Network Connection

and try again, it looks like visibility.

Answer 5

You can also try to execute the command below using a project,

 $ git config --global url."https://".insteadOf git://
