Force m2e to use http instead of https

问题

My eclipse installation always uses the https protocol to download repository structures. The problem is that my cooperate proxy wont let me use https on this url. How to force m2e to use http?

I tried with different external maven installations for m2e but no luck. It only works if i use the external maven from CLI, which uses http.

I'd recommend using an external Maven installation anyway, don't rely on the built-in version. In your Maven directory, find the <maven>/conf/settings.xml file. There you can edit your proxy settings:

<settings>
  <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>

  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>insecurecentral</activeProfile>
  </activeProfiles>
  <profiles>
    <profile>
      <id>insecurecentral</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>

Also, you should update your Maven settings in Eclipse (Maven -> User Settings):

I had a similar problem and I fixed that adding the code below to my pom.xml:

<repositories>
    <repository>
        <id>central-repo</id>
        <name>Central Repository</name>
        <url>http://repo1.maven.org/maven2</url>
    </repository>
</repositories>
