Unable to resolve rmlmapper dependency in Maven Central

[IanEmmons]

My Java project's Gradle build script looks like so:

plugins {
    id 'java-library'
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'be.ugent.rml:rmlmapper:4.10.0'
}

When I try to build, I get the following error:

% ./gradlew build
> Task :compileJava FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.
> Could not resolve all files for configuration ':compileClasspath'.

     If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.

Do I need to specify another dependency repository to resolve these two missing dependencies?

Could you try it with the two repositories also used by the RMLMapper pom itself?

    <repositories>
        <repository>
            <id>repo.maven.apache.org</id>
            <url>https://repo.maven.apache.org/maven2/</url>
        </repository>
        <repository>
            <id>jitpack.io</id>
            <url>https://jitpack.io</url>
        </repository>
    </repositories>

This work-around does indeed work, so I'm going to close the issue. However, in the future, it would make rmlmapper much easier to use if all its dependencies were accessible in Maven Central. (BTW, the first of the two URLs you give above is Maven Central.)
