java-driver-mapper-processor cannot find symbol for MapperBuilder

I tried to use the mapper based on https://docs.datastax.com/en/developer/java-driver/4.8/manual/mapper/config/

<plugin>
   <artifactId>maven-compiler-plugin</artifactId>
   <version>3.8.1</version>
   <configuration>
      <source>1.8</source> <!-- (or higher) -->
      <target>1.8</target> <!-- (or higher) -->
      <annotationProcessorPaths>
         <path>
            <groupId>com.datastax.oss</groupId>
            <artifactId>java-driver-mapper-processor</artifactId>
            <version>4.8.0</version>
         </path>
      </annotationProcessorPaths>
   </configuration>
</plugin>

When I tried to build it using mvn install, it complained that it cannot find the related MapperBuilder. Annotation processing is not working for me.

I also tried adding the dependency

<dependency>
   <groupId>com.datastax.oss</groupId>
   <artifactId>java-driver-mapper-processor</artifactId>
   <version>${datastax.driver.version}</version>
   <scope>provided</scope>
</dependency>

I can build it in Intellij with "Annotation Processing" enabled in the project but not able to build it using command line. The maven version used in Intellij and command line are the same (3.6.1)

Could you please edit your original question (please don't post it as an "answer") with the full contents of your pom.xml? Cheers!

Hi,

Your configuration seems quite legit to me.

Here is `pom.xml` that compile with Maven as expected.

Checking discrepancies:

https://github.com/clun/spring-petclinic-reactive/blob/master/pom.xml

bump to latest version `4.9.0`
I did not used the `provided` keyword in definition of the annotation processor

<cassandra-java-driver.version>4.9.0</cassandra-java-driver.version> <cassandra-native-protocol.version>1.4.11</cassandra-native-protocol.version>

Then

<dependency> 
 <groupId>com.datastax.oss</groupId>
 <artifactId>java-driver-core</artifactId>
 <version>${cassandra-java-driver.version}</version>
 <exclusions>
   <exclusion>
     <groupId>org.apache.tinkerpop</groupId>
     <artifactId>*</artifactId> 
    </exclusion>
 </exclusions> 
</dependency> 

<dependency>
 <groupId>com.datastax.oss</groupId>
 <artifactId>java-driver-query-builder</artifactId>
 <version>${cassandra-java-driver.version}</version>
</dependency>

<dependency>
 <groupId>com.datastax.oss</groupId>
 <artifactId>java-driver-mapper-runtime</artifactId>
 <version>${cassandra-java-driver.version}</version>
</dependency>

<dependency>
 <groupId>com.datastax.oss</groupId>
 <artifactId>native-protocol</artifactId>
 <version>${cassandra-native-protocol.version}</version>
</dependency>
</dependencies> 

<build>
 <plugins>
   <plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <configuration> 
     <release>${java.version}</release> 
     <source>${java.version}</source> 
     <target>${java.version}</target> 
     <showWarnings>false</showWarnings> 
     <annotationProcessorPaths> 
      <path> 
        <groupId>com.datastax.oss</groupId> 
        <artifactId>java-driver-mapper-processor</artifactId> 
        <version>${cassandra-java-driver.version}</version> 
       </path> 
      </annotationProcessorPaths> 
     </configuration>
    </plugin>
   </plugins>
</build>

1. My company does not have 4.9 in the repository yet.

2. I did not use the `provided` keyword in definition of the annotation processor in the build plugin neither. If I did not use annotation processing in the build and put it in the dependency, it will build using Intellij with annotation processing enabled. However, it won't build in command line.

3. After taking the pom you pasted, I still cannot build.
