JitPack Maven PluginResolutionException

Question

i want to use https://github.com/NiklasHoltmeyer/maven-endpointscoverage

without having to clone it:

https://jitpack.io/#NiklasHoltmeyer/maven-endpointscoverage

Pom.xml:

<project ...

    <repositories>
        <repository>
            <id>jitpack.io</id>
            <url>https://jitpack.io</url>
        </repository>
    </repositories>

    <build>
        <plugins>
            <plugin>
                <!--
                 <groupId>de.hsos.bachelorarbeit.nh</groupId>
                  <artifactId>endpointscoverage-maven-plugin</artifactId>
                  <version>1.0.0</version>
                  -->
                <groupId>com.github.NiklasHoltmeyer</groupId>

                ... config ..
            </plugin>
...

[ERROR] Plugin com.github.NiklasHoltmeyer:maven-endpointscoverage:1.0.0 or one of its dependencies could not be resolved: Could not find artifact com.github.NiklasHoltmeyer:maven-endpointscoverage:jar:1.0.0 in central (https://repo.maven.apache.org/maven2) -> [
Help 1]

If i compile the Plugin and change the groupId / artifactId according to everything inside the Commentblock it works..

I also tried the following versions:

• 1.0.0
• master
• master-f2d0242df8-1
• master-SNAPSHOT
• -SNAPSHOT
• RELEASE
• LATEST

It would be great if someone could help me

Answer 1

Add this to your pom:

<pluginRepositories>
    <pluginRepository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </pluginRepository>
</pluginRepositories>

Because you are using a plugin. Your code with <repositories> covers only the dependencies, not the plugin dependencies.

Keep the rest as it is and run mvn dependency:resolve-plugins command to resolve you plugin dependencies.
