Dependencies missing when using solr-core-10.0.0 instead of 9.10.1

[Thorsten Heit]

Hi,







- a common module that represents the bridge to Solr (by using SolrJ)





<dependencies>
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-core</artifactId>
    </dependency>
    <dependency>
        <groupId>${project.groupId}</groupId>
        <!-- bridge to connect to Solr: -->
        <artifactId>solr-connector-common</artifactId>
        <version>${project.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.solr</groupId>
        <artifactId>solr-core</artifactId>
        <version>${solr.version}</version>
    </dependency>

    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-engine</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-params</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

(the property "solr.version" is defined in the parent pom)


With solr-core-9.10.1 "mvn dependency:tree" gives me

(...)

What puzzles me that the same command with solr-core-10.0.0 only shows

(...)

But:







Has somehere a clue why this is necessary?

I have asked this on the Solr mailing list before, but got no helpful answer so far. I hope someone here as a glue what's going on: I have written an internal library that uses SolrJ for connecting to a (remote) Solr server. The library is a multi-module project consisting of several parts; the interesting ones are: - a test module that implements JUnit tests and an integration test; uses jetty-maven-plugin to start a local Solr server with an empty database before the IT is executed Actually I'm using the following dependencies in the IT module pom (unnecessary parts omitted): i.e. no dependencies at all in solr-core-10.0.0 in the tree. Therefore the IT test fails with ClassNotFoundExceptions when Jetty starts the local server: [WARNING] Failed startup of context oeje10mp.MavenWebAppContext@54bd2345{/solr,/solr,b=file:///(...)/solr-connector-tests/src/main/webapp/,a=STOPPED,h=oeje10s.SessionHandler@10897221{STOPPED}}{file:///(...)/solr-connector-tests/src/main/webapp/} java.lang.NoClassDefFoundError: org/apache/solr/common/cloud/ClusterPropertiesListener at org.eclipse.jetty.ee10.servlet.ServletContextHandler$ServletScopedContext.createInstance (ServletContextHandler.java:2023) at org.eclipse.jetty.ee10.servlet.BaseHolder.createInstance (BaseHolder.java:203) When you look at the pom of solr-core-10.0.0 there are indeed lots of dependencies; if I counted correctly 76 in sum, 9 having scope "compiled" and 67 with scope "runtime". Additionally the poms of solr-core-9.10.1 and solr-core-10.0.0 don't differ much. The dependencies are basically the same, some with newer versions; a few removed, a few added IIRC. To make the IT work again I manually have to add about a third of the dependencies defined in solr-core-10.0.0 such as org.apache.solr:solr-solrj, org.apache.solr:solr-solrj-zookeeper, tons of lucene dependencies etc.
