Could not find artifact in maven central repo when search returns a match

Question

I am attempting to introduce a dependency on the castor library in my pom. Since my project is at a preliminary stage, all artifacts are from maven central. So I search in search.maven.org for "castor". I take the first result which gives me the following dependency snippet:

<dependency>
    <groupId>org.codehaus.castor</groupId>
    <artifactId>castor</artifactId>
    <version>1.3.3</version>
</dependency>

Now I "mvn clean install" and get the following:

[ERROR] Failed to execute goal on project jaxb: Could not resolve dependencies for project org.test:jaxb:war:0.0.1-SNAPSHOT: Could not find artifact org.codehaus.castor:castor:jar:1.3.3 in central (https://repo.maven.apache.org/maven2) -> [Help 1]

How come a artifact that can be found from the web interface cannot be found by the CLI. I am certainly missing something. Request pointers on what it could be.

Among other posts, I have looked into this and this posts which are related, but not this issue.

Answer 1

The problem you have is that the artifact which you have defined as a dependency:

<dependency>
    <groupId>org.codehaus.castor</groupId>
    <artifactId>castor</artifactId>
    <version>1.3.3</version>
</dependency>

defines a jar artifact as the error messages implies: org.codehaus.castor:castor:jar:1.3.3

The problem is that on Maven Central this kind of artifact does not exist. It only exist a pom file but not a jar file.
