junit Maven：未找到Log4j类

我有一个项目，我已经为它添加了一个可选的依赖项到Log4j：

<dependency>
      <groupId>org.apache.logging.log4j</groupId>
      <artifactId>log4j-core</artifactId>
      <version>2.19.0</version>
      <optional>true</optional>
    </dependency>

在我的模块描述符中，我添加了实现和API的要求：

requires static org.apache.logging.log4j;
    requires static org.apache.logging.log4j.core;

如果我将项目构建为预模块项目，则项目会成功构建。但是，当我将项目构建为模块时，JUnit会失败。虽然最初错误并不明显，但将-e添加到Maven命令中会显示以下错误：

不幸的是，这就是我遇到的问题。当我添加-X时，我发现在编译和运行测试时，API和核心模块都被添加到了模块路径中。这来自于创建的surefireargs文件：

我也尝试过打开类的包，但随后我得到以下警告：

WARNING: Unknown module: org.apache.logging.log4j specified to --add-opens

因此，即使两个Log4j模块都被添加到模块路径中，并且org.apache.logging.log4j.util.Supplier存在于JAR文件中，但是在运行测试时却找不到它。GitHub操作也会失败：https://github.com/robtimus/junit-support/actions/runs/3558874573/jobs/5977845973
编辑：添加以下插件无法解决此问题（插件的源和目标已设置为11）：

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
              <release>11</release>
            </configuration>
          </plugin>

我已经通过添加--add-modules到surefire插件的argLine中解决了这个问题。我不仅要添加Logj4，还要添加logback，它也有同样的问题。另外，因为我添加了一些自定义的测试附加器到日志配置中，所以我还必须打开这些模块的包。
结果：

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
              <argLine>
                --add-modules org.apache.logging.log4j
                --add-modules ch.qos.logback.classic
                --add-modules ch.qos.logback.core

                --add-opens com.github.robtimus.junit.support/com.github.robtimus.junit.support.extension.testlogger=java.logging
                --add-opens com.github.robtimus.junit.support/com.github.robtimus.junit.support.extension.testlogger=org.apache.logging.log4j.core
                --add-opens com.github.robtimus.junit.support/com.github.robtimus.junit.support.extension.testlogger=ch.qos.logback.core
                --add-opens com.github.robtimus.junit.support/com.github.robtimus.junit.support.extension.testlogger=ch.qos.reload4j

                <!-- other existing add-opens omitted -->
              </argLine>
            </configuration>
          </plugin>
