The error message you’re encountering indicates that Maven cannot find the repository element in your pom.xml file’s distributionManagement section, which is required for deploying artifacts. This typically happens when you are trying to deploy a project without specifying where to deploy it.

Let’s go through your pom.xml and identify the issues and solutions step by step.

Issues Identified

  1. Missing repository URLs: The URLs in your distributionManagement section are missing a double slashes (//) after the protocol (https:). They should be https://.
  2. Deployment Configuration: Ensure that your pom.xml has the necessary configuration in the distributionManagement section to specify where to deploy your artifacts.

Corrected pom.xml

Here’s a corrected version of your pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            <releases>
                <enabled>false</enabled>
            </releases>
        </repository>
    </repositories>

    <distributionManagement>
        <repository>

            <name>SIGIT Release Repository</name>

        <snapshotRepository>
            <id>sigit-snapshots</id>
            <name>Project Snapshots Repository</name>
            <url>https://sigit.com/nexus/content/repositories/uib-snapshots/</url>
            <uniqueVersion>false</uniqueVersion>
        </snapshotRepository>
    </distributionManagement>
</project>

Key Changes Made

  1. Fixed URLs: Changed https:sigit.com to https://sigit.com.
  2. Name Consistency: Ensured that the names of the repositories in the repositories and distributionManagement sections are consistent and descriptive.

Additional Steps to Ensure Successful Deployment

  1. Run Maven Deploy Command: Use the following command to deploy:
mvn clean deploy
  1. Check Network Connectivity: Ensure your machine can reach the specified URLs, and there are no firewall rules blocking access.
  2. Authentication: If your Nexus repository requires authentication, ensure you have configured your credentials in your ~/.m2/settings.xml file. Here’s an example:
<servers>
    <server>
        <id>sigit-releases</id>
        <username>your-username</username>
        <password>your-password</password>
    </server>
    <server>
        <id>sigit-snapshots</id>
        <username>your-username</username>
        <password>your-password</password>
    </server>
</servers>
  1. Enable Debugging: If you continue to face issues, enable debug logging for more details:
mvn deploy -X

By making these adjustments and ensuring your environment is correctly set up, you should be able to successfully deploy your Maven project. If any other errors arise, the debug logs can provide further insights into the issue.
