寻找不存在的log4j文件的Maven jar插件

标签: java maven logging jar log4j

我的项目没有引用C:\ log4j-application.log的log4j配置文件,但maven有错误,因为它不存在。这是在Linux系统上。 “mvn package”命令出错:

我的应用中的典型log4j.properties:

# Root logger option
log4j.rootLogger=DEBUG, stdout, file

# Redirect log messages to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

# Redirect log messages to a log file, support file rolling.
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

org.jooq.Constants.level=WARNING

是什么导致这个?到目前为止试图:

  • mvn clean,删除.m2 / repository
  • 从模块e中删除log4j
  • 很多谷歌搜索

答案 0 :(得分:0)

好的,这绝对是我的疏忽。在导致问题的e / src / main / resources中有一个名为C:\ log4j-application.log的延迟文件。一旦它被删除,我跑了一个maven干净,一切都按预期工作。

我认为我开始使用的log4j配置文件设置为C:\ log4j-application.log然后我开始收到错误,因为它不存在。当时我在几个地方使用touch创建了一个具有该名称的文件以绕过错误,但我从未删除所有这些错误。它是一个空文件,所以我的grep -R log4j-application .命令从未找到它(我希望某个配置文件引用该文件)。捂脸。
