为什么log4j2在Windows Bash控制台中丢弃错误

Question

早上好，

在我的项目中使用log4j2（请参见在配置下方）运行它，Eclipse中的一切都可以。然后构建罐子并在bash窗口中执行，我会发现"控制台appender"的错误。经过调查后，它在其他外壳（例如git bash）中起作用，我的问题是在某个地方记录了这种行为吗？

我的log4j2.properties：

   name=PropertiesConfig
   property.directory = ./logs
   appenders = console, file, testFile
   appender.console.type = Console
   appender.console.target =SYSTEM_OUT
   appender.console.name = STDOUT
   appender.console.layout.type = PatternLayout
   appender.console.layout.pattern = [%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} line %L - %msg%n
   appender.file.type = File
   appender.file.append = false
   appender.file.name = LOGFILE
   appender.file.fileName=${directory}/neoswitcher-${date:yyyy-MM-dd-HH-mm-ss}.log
   appender.file.layout.type=PatternLayout
   appender.file.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
   appender.testFile.type = File
   appender.testFile.append = false
   appender.testFile.name = LOGTestFILE
   appender.testFile.fileName=${directory}/test-suite-${date:yyyy-MM-dd-HH-mm-ss}.log
   appender.testFile.layout.type=PatternLayout
   appender.testFile.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
   loggers=file
   logger.file.name=org.test.controller.core
   logger.file.level = info
   logger.file.appenderRefs = file
   logger.file.appenderRef.file.ref = LOGFILE
   loggers=file
   logger.testFile.name=org.simpleperftests.core;
   logger.testFile.level = info
   logger.testFile.appenderRefs = testFile
   logger.testFile.appenderRef.file.ref = LOGTestFILE
   rootLogger.level = info
   rootLogger.appenderRefs = stdout, file, testFile
   rootLogger.appenderRef.stdout.ref = STDOUT
   rootLogger.appenderRef.file.ref = LOGFILE
   rootLogger.appenderRef.testFile.ref = LOGTestFILE

以及MS-DOS控制台中发生的错误：

编辑：实际上在Linux上可以使用该版本

Answer 1

使用快照版本（版本2.8.1-snapshot）测试后，该错误已修复。

log4j2的快照版本可在此存储库中找到：https：//repository.apache.org/content/repositories/snapshots/

Answer 2

使用版本2.8.1而不是2.8.0似乎解决了我的问题

        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-api</artifactId>
            <version>2.8.1</version>
        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-core</artifactId>
            <version>2.8.1</version>
        </dependency>

Answer 3

i在Windows命令ProMT中也遇到了相同的问题。我尝试了git bash，它照常工作正常。

因此，安装git bash并尝试进行git bash，它应该可以正常工作。
