通过为Maven使用备用存储库，我无法下载Java项目中的某些依赖项？

Question

I am working behind a proxy and I am facing SSL issues. Therefore, I can't use HTTPS propertly, so in Eclipse in the settings.xml file of maven I set the repository to " http://repo1.maven.org/maven2 ", ie HTTP, as follows:

<settings>
  <activeProfiles>
    <activeProfile>securecentral</activeProfile>
  </activeProfiles>
  <profiles>
    <profile>
      <id>securecentral</id>
      <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>

It worked for some dependencies but when I added one dependency to the pom.xml specifically this one:

<dependency>
    <groupId>com.twelvemonkeys.imageio</groupId>
    <artifactId>imageio-tiff</artifactId>
    <version>3.3.2</version>
</dependency>

Eclipse couldn't download it (I don't know if this issue is from the proxy, from the repository itself, or some other issue)

My question: Does setting the repository to " http://repo1.maven.org/maven2 " limit the number of plugins, libraries, or anything I can download using the normal repository " https://mvnrepository.com/ ", or it is exactly the same without any limitation or difference except that the first one is through HTTP not HTTPS ?

Answer 1

I hope you understand that both of these are repositories which include artifacts uploaded via distributionManagement by developers.

They are not same in terms of the endpoint you would reach.

The preferred would be the one for maven central - http://repo1.maven.org/maven2 which can be looked in at https://search.maven.org/

There is a useful link for consumers to start using it. - central.sonatype.org/pages/consumers and the code shared seems to be following that very likely ( Consumer - Apache Maven )
