    Plugin org.codehaus.mojo:gwt-maven-plugin:2.10.0 or one of its dependencies could not be resolved

    Hi GWT Experts,

    I am new to GWT world of development. Doing a fresh GWT maven based project setup. Below is my system configuration details:
    • Java Version: 1.17
    • Eclipse Version: 2023-03 (4.27.0)
    • GWT SDK: 2.11.0
    • GWT Plugin: 4.0.0
    • Maven: 3.9.6

    I found an article (link) which talks about GWT Basic Archetype for creating a GWT Maven project .
    Code:
    mvn archetype:generate ^
-DarchetypeRepository=https://oss.sonatype.org/content/repositories/snapshots ^
-DarchetypeGroupId=com.github.branflake2267.archetypes ^
-DarchetypeArtifactId=gwt-basic-archetype ^
-DarchetypeVersion=2.0-SNAPSHOT ^
-DgroupId=com.example.project.ChangeMe ^
-DartifactId=new-project-name-ChangeMe
    While running I get BUILD FAILED with error:
    Code:
    Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.2.1:generate (default-cli) on project standalone-pom: The desired archetype does not exist (com.github.branflake2267.archetypes:gwt-basic-archetype:2.0-SNAPSHOT)
    So I tried generating with maven-archetype-plugin:2.4 and manually update the config.

    Maven generate with maven-archetype-plugin:2.4

    Code:
    mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate \
-DarchetypeRepository=[URL]https://oss.sonatype.org/content/repositories/snapshots[/URL] \
-DarchetypeGroupId=com.github.branflake2267.archetypes \
-DarchetypeArtifactId=gwt-basic-archetype \
-DarchetypeVersion=2.0-SNAPSHOT \
-DgroupId=com.example.project.ChangeMe \
-DartifactId=new-project-name-ChangeMe
    Here is what my pom looks like:
    Code:
    <?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    The easiest thing would be to start all over using the Smart GWT Pro/EE Project Setup documentation as your guide, but you can skip directly to the Maven Support topic if you're already familiar with Maven.

    Do let us know if you have any trouble at that point.
