Maven:没有找到Log4j类

Question

我有一个项目，我已经为Log4j添加了一个可选的依赖项:

<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的需求:

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，则项目构建成功。但是，当我将项目构建为模块时，JUnit失败了。虽然最初的错误并不清楚，但将-e添加到Maven命令中会显示以下错误:

不幸的是，这就是我卡住的地方。当我添加-X时，我看到API和核心模块在编译和运行测试时都被添加到模块路径中。这是从创建的surefireargs文件:

我也尝试打开类的包，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模块都添加到模块路径中，并且org.apache.logging.log4j.util.Supplier存在于JAR文件中，但在运行测试时无法找到它。这甚至没有本地化到我的本地机器;GitHub动作也失败了:https://github.com/robtimus/junit-support/actions/runs/3558874573/jobs/5977845973

编辑:添加以下插件并不能解决问题(插件已经将源和目标设置为11):

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

Answer 1

我通过将--add-modules添加到surefire插件的argLine来解决这个问题。我不仅要添加Logj4，还要添加logback，它们都有同样的问题。另外，因为我在日志配置中添加了一些自定义测试附件，所以我也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>
