Solution 1

Your debug output indicates that Clean is the first thing that it's trying to run, so I'm guessing it's failing to download any plugins from central.

First off, see if you can download the plugin jar directly in a web browser: http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.jar

If that works then your web browser has connectivity to central but maven doesn't. That suggests to me that your web browser is using a proxy that maven isn't configured to use.

Maven proxy settings are described in depth here. To simplify that a little fill this out (replace the protocol/host/port with the values from your internet settings) and put it in the <settings> tag of your maven settings.xml file:

<proxies>
  <proxy>
    <id>proxy</id>
    <active>true</active>
    <protocol>http</protocol>
    <host>proxy.example.com</host>
    <port>8080</port>
  </proxy>
</proxies>

Solution 2

The error is due to maven official repository being not accessible. This repo (https://repo.maven.apache.org/maven2/) is not accessible so follow these steps:

  1. Firstly delete your /home/user/.m2 folder
  2. create .m2 folder at user home and repository folder within .m2
  3. copy the default settings.xml to .m2 folder
  4. Change mirrors as follows in the settings.xml as shown in below snap mirror_settings 

<mirrors>
  <mirror>
    <id>UK</id>
    <name>UK Central</name>
    <url>http://uk.maven.org/maven2</url>
    <mirrorOf>central</mirrorOf>
  </mirror>
</mirrors>
  1. Execute the mvn clean commands now .....

Solution 3

In my case my problem was that I was using an older version of NetBeans. The Maven repository removed an http reference, but the embedded Maven in Netbeans had that http reference hard-coded. I was really confused at first because my pom.xml referenced the proper https://repo.maven.apache.org/maven2.

Fixing it was pretty simple. I downloaded the latest zip archive of Maven from the following location and extracted it to my machine: https://maven.apache.org/download.cgi

Within Netbeans at Tools -> Options -> Java -> Maven on the "Execution" section I set "Maven Home" to the newly extracted zip file location.

Now I could build my project....

Solution 4

It might be that you are forgetting to specify the settings which was the case with me.

Try:

mvn clean install -s settings_file.xml

Solution 5

I faced the same problem, even if I was working on my home wifi connection, without any proxy requirements.

My project was created at c:\users\<>\Workspace\Project\

When I went to above location and ran

mvn clean install

I got below error: 

[ERROR] Plugin org.apache.maven.plugins:maven-clean-plugin:2.5 or one of its de
endencies could not be resolved: Failed to read artifact descriptor for org.apa
he.maven.plugins:maven-clean-plugin:jar:2.5: Could not transfer artifact org.ap
che.maven.plugins:maven-clean-plugin:pom:2.5 from/to central (https://repo.mave
.apache.org/maven2)

It took me entire day to try ways and means to crack this, but the solution in my case, was damn simple.

I moved my project to non-user specific location, at E:\Workspace\Project\

This has done wonders for me!

    I have install maven in my machine. I have properly set the class-path and maven home folder. Every time I execute mvn clean install, it gives me exception. I have also tried to delete the .m2 folder but the same result.
