Problems using Maven and SSL behind proxy

You can use the -Dmaven.wagon.http.ssl.insecure=true option

The answer above is a good working solution, but here's how to do it if you want to use the SSL repo:

• Use a browser (I used IE) to go to https://repo.maven.apache.org/
  • Click on lock icon and choose "View Certificate"
  • Go to the "Details" tab and choose "Save to File"
  • Choose type "Base 64 X.509 (.CER)" and save it somewhere

• Now open a command prompt and type (use your own paths):

  keytool -import -file C:\temp\mavenCert.cer -keystore C:\temp\mavenKeystore

• Now you can run the command again with the parameter

  -Djavax.net.ssl.trustStore=C:\temp\mavenKeystore

• Under linux use absolute path

  -Djavax.net.ssl.trustStore=/tmp/mavenKeystore

  otherwise this will happen

• Like this:

  mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false -Djavax.net.ssl.trustStore=C:\temp\mavenKeystore

Optional:

You can use the MAVEN_OPTS environment variable so you don't have to worry about it again. See more info on the MAVEN_OPTS variable here:

The fact is that your maven plugin try to connect to an https remote repository
(e.g https://repo.maven.apache.org/maven2/)

This is a new SSL connectivity for Maven Central was made available in august, 2014 !

So please, can you verify that your settings.xml has the correct configuration.

    <settings>
  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>securecentral</activeProfile>
  </activeProfiles>
  <profiles>
    <profile>
      <id>securecentral</id>
      <!--Override the repository (and pluginRepository) "central" from the
         Maven Super POM -->
      <repositories>
        <repository>
          <id>central</id>
          <url>http://repo1.maven.org/maven2</url>
          <releases>
            <enabled>true</enabled>
          </releases>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>central</id>
          <url>http://repo1.maven.org/maven2</url>
          <releases>
            <enabled>true</enabled>
          </releases>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
</settings>

You can alternatively use the simple http maven repository like this

 <pluginRepositories>
    <pluginRepository>
      <id>central</id>
      <name>Maven Plugin Repository</name>
      <url>http://repo1.maven.org/maven2</url>
      <layout>default</layout>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
      <releases>
        <updatePolicy>never</updatePolicy>
      </releases>
    </pluginRepository>
  </pluginRepositories>

Please let me know if my solution works ;)
