Efficient Resolution for 501 HTTPS Required Error in Maven Build for Moving (http://repo1.maven.org/maven2 & http://repo.spring.io) to HTTPS?

Question

Need Efficient Solution for moving to HTTPS for mvn clean install build success

Have project with numerous internal dependencies which use http://repo1.maven.org/maven2 & http://repo.spring.io for dependency download

Tried following solutions at my end

Added following settings.xml in ~/.m2/ folder. Tried Profiling options also.

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"

Still faced some issues for internal jars dependencies in the project.

Failed to read artifact descriptor for com.netflix.hystrix:hystrix-core:jar:1.5.13: Could not transfer artifact com.netflix.hystrix:hystrix-core:pom:1.5.13 from/to cxf-repo (http://repo1.maven.org/maven2/): Transfer failed for http://repo1.maven.org/maven2/com/netflix/hystrix/hystrix-core/1.5.13/hystrix-core-1.5.13.pom 501 HTTPS Required

Added following in pom.xml

      <repositories>
        <repository>
            <id>central-maven</id>
            <name>central https Releases</name>
            <url>https://repo.maven.apache.org/maven2</url>
        </repository>
        <repository>
            <id>central-spring</id>
            <name>central spring https Releases</name>
            <url>https://repo.spring.io</url>
        </repository>
      <repositories>

Have read this doc for maven central repo movement to HTTPS https://blog.sonatype.com/central-repository-moving-to-https but couldn't get any proper resolution for internal dependency issue.

Some dependencies in my case are still calling http url's of central and spring maven

take backup of m2 folder and create empty .m2 folder . clean maven repo and start from scratch. I know it is time taking process. but it may help ! — Mandar Dharurkar, Jan 20 '20 at 02:39
Or i would suggest to mvn generate dependency tree in your project that will tell us exactly which component is calling this and remove that dependency from m2 folder — Mandar Dharurkar, Jan 20 '20 at 02:41
Go through this and find a solution that works for you. https://stackoverflow.com/questions/59763531/maven-dependencies-are-failing-with-a-501-error I used the answer from Sumeet Vishwas and changing maven to use the latest version for netbeans. — Sanal S, Jan 27 '20 at 04:21

Either upgrade your Maven version or

Restrict the current Maven version to use HTTPS links by modifying your POM:

Include the following code in pom.xml of your project.

<project>
  ...
<repositories>
    <repository>
        <id>central</id>
        <name>Central Repository</name>
        <url>https://repo.maven.apache.org/maven2</url>
        <layout>default</layout>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

taking a backup of .m2 folder and doing clean and install worked for me.
