java.lang.IllegalArgumentException: The `GraalVmProcessor` annotation processor
is missing the required `log4j.graalvm.groupId` and `log4j.graalvm.artifactId`
options
To keep deprecated code out of our codebase, we enable deprecation warnings and
treat compilation warnings as errors, in order to break the build and call
attention to the deprecated code usage.
```xml
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.13.0</version>
<configuration>
<compilerArgs>
<!-- Treat Warnings as Errors -->
<arg>-Werror</arg>
<!-- Enable deprecation warnings -->
<arg>-Xlint:deprecation</arg>
</compilerArgs>
<showWarnings>true</showWarnings>
<!--
https://issues.apache.org/jira/browse/MCOMPILER-209 -->
<useIncrementalCompilation>false</useIncrementalCompilation>
</configuration>
</plugin>
```
We do not use Graal.
We do not have any custom annotation processors.
We do use Mockito.
I tried upgrading from 2.24.3 to 2.25.1 but the build fails with:
```shell
...
[WARNING] COMPILATION WARNING :
[INFO] -------------------------------------------------------------
[WARNING] The `GraalVmProcessor` annotation processor is missing the
recommended `log4j.graalvm.groupId` and `log4j.graalvm.artifactId` options.
To follow the GraalVM recommendations, please add the following options to
your build tool:
-Alog4j.graalvm.groupId=<groupId>
-Alog4j.graalvm.artifactId=<artifactId>
[INFO] 1 warning
[INFO] -------------------------------------------------------------
[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] warnings found and -Werror specified
[INFO] 1 error
...
```
Due to our steps to keep deprecated code out of the codebase, this warning, for
something we do not use and do not care about, is breaking the build. It
doesn't make sense to have to provide useless configuration in N different
builds to make this go away.
