java.lang.IllegalArgumentException: The `GraalVmProcessor` annotation processor
is missing the required `log4j.graalvm.groupId` and `log4j.graalvm.artifactId`
options
Hi @ratoaq2,
Thanks for the detailed error log — it's very helpful.
>From what you've shared, the issue is occurring during the `default-compile`
>Maven Compiler Plugin execution, not in the custom
>`generate-log4j-plugin-descriptor` execution you configured. Specifically:
```
[INFO] --- compiler:3.14.0:compile (default-compile) @ common ---
[INFO] Compiling with eclipse [...] to target/classes
[ERROR] Internal compiler error: java.lang.IllegalArgumentException:
The `GraalVmProcessor` annotation processor is missing the required
`log4j.graalvm.groupId` and `log4j.graalvm.artifactId` options.
```
If you want to use a separate execution for annotation processing, you need to
disable annotation processing in `default-compile`:
```xml
<execution>
<id>default-compile</id>
<configuration>
<proc>none</proc>
</configuration>
</execution>
```
If, on the other hand, you want to perform both compilation and annotation
processing (Log4j plugin descriptor + GraalVM metadata) **in a single Maven
execution**, you can fully configure the `default-compile` phase like this:
```xml
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.14.0</version>
<dependencies>
<dependency>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-compiler-eclipse</artifactId>
<version>2.15.0</version>
</dependency>
</dependencies>
<configuration>
<!-- Use Eclipse Compiler explicitly -->
<compilerId>eclipse</compilerId>
<release>21</release>
<!-- Default to no annotation processing unless explicitly enabled -->
<proc>none</proc>
</configuration>
<executions>
<execution>
<id>default-compile</id>
<configuration>
<!-- Enable annotation processing in this phase -->
<proc>only</proc>
<annotationProcessorPaths>
<path>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.25.0</version>
</path>
</annotationProcessorPaths>
<annotationProcessors>
<annotationProcessor>
org.apache.logging.log4j.core.config.plugins.processor.PluginProcessor
</annotationProcessor>
<annotationProcessor>
org.apache.logging.log4j.core.config.plugins.processor.GraalVmProcessor
</annotationProcessor>
</annotationProcessors>
<compilerArgs>
<!-- Required arguments for GraalVmProcessor -->
<arg>-Alog4j.graalvm.groupId=${project.groupId}</arg>
<arg>-Alog4j.graalvm.artifactId=${project.artifactId}</arg>
</compilerArgs>
</configuration>
</execution>
</executions>
</plugin>
```
I hope that helps solving your problem.
