How to change maven's Remote Repository URL in the NetBeans IDE (from http to https)?

问题

When trying to run a NetBeans project, I get the following error message:

Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.10:test (default-test) on project MyNetBeansProject: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.10:test failed: Plugin org.apache.maven.plugins:maven-surefire-plugin:2.10 or one of its dependencies could not be resolved: Failed to collect dependencies for org.apache.maven.plugins:maven-surefire-plugin:jar:2.10 (): Failed to read artifact descriptor for org.apache.maven.surefire:surefire-booter:jar:2.10: Could not transfer artifact org.apache.maven.surefire:surefire-booter:pom:2.10 from/to central (http://repo.maven.apache.org/maven2): Failed to transfer file: http://repo.maven.apache.org/maven2/org/apache/maven/surefire/surefire-booter/2.10/surefire-booter-2.10.pom. Return code is: 501 , ReasonPhrase:HTTPS Required. -> [Help 1]

The following part of the error message is the most important one:

Failed to transfer file: http://repo.maven.apache.org/maven2/org/apache/maven/surefire/surefire-booter/2.10/surefire-booter-2.10.pom. Return code is: 501 , ReasonPhrase:HTTPS Required.

Services -> Maven Repositories -> Central Repository -> right mouse click on "Central Repository" gives the following information:

As one can see, the Remote Repository URL is "http://repo.maven.apache.org/maven2/". I think it should instead be "https://repo.maven.apache.org/maven2/". However, the problem is that I can't seem to change the Remote Repository URL.

Does anybody know how to change maven's Remote Repository URL in the NetBeans IDE?

UPDATE:

Under NetBeans -> Preferences one can see that the maven version used by my NetBeans IDE is Version 3.0.5:

回答1:

I think you have three options.

1. Migrate to 11.0

You can migrate to Netbeans 11.0 LTS (or 11.2), it uses a built-in Maven 3.3.9 version. It already uses https.

2. Install standalone Apache Maven

You can stay with Netbeans 8.2 but download standalone apache maven, install it to your system and set the path to the new maven home directory in Options -> Java -> Maven -> Maven Home.

You need just:

Download apache-maven-3.6.3-bin.zip (or apache-maven-3.6.3-bin.tar.gz) from Apache
Unzip it to any directory. It will be the Maven home.
Set the Maven home directory in NetBeans to the directory where you have extracted zip file.
Ensure than you have set JAVA_HOME in your environment variables

Instructions how to install standalone version here.

If you set the Maven Home in NetBeans correctly it will show you updated version:

3. Quick and not recommended

Just add repositories into your pom.xml with https (for example like that)

<repositories>
        <repository>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
            <id>central</id>
            <name>Central Repository</name>
            <url>https://repo.maven.apache.org/maven2</url>
        </repository>
    </repositories>
<pluginRepositories>
    <pluginRepository>
        <releases>
            <updatePolicy>never</updatePolicy>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
        <id>central</id>
        <name>Central Repository</name>
        <url>https://repo.maven.apache.org/maven2</url>
    </pluginRepository>
</pluginRepositories>

Maven Central Migrated to https

The problem comes from this:

As of January 15, 2020, The Central Repository no longer supports insecure communication over HTTP and requires that all requests to the repository are encrypted over HTTPS.

Here is the relevant improvement that was resolved and relevant changes.

回答2:

Within the Netbeans installation, this worked for me:

Goto Netbeans installation folder > java > maven > conf, and here I updated the settings.xml file using administrative privilege.

as http repo link will not work now, just I created an mirror for central repo that is pre-built with IDE which cannot be changed.

Add this inside mirrors tag of settings.xml

<mirror>
      <id>mirror1</id>
      <mirrorOf>central</mirrorOf>
      <name>mirror1</name>
      <url>https://repo.maven.apache.org/maven2/</url>
</mirror>

after this restart netbeans IDE, and central repository will be overridden with the mirror we specify.
