SLF4J：无法加载类“org.slf4j.impl.StaticLoggerBinder”。错误 [英] SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". error
问题描述
- 关于Eclipse IDE （靛蓝， Juno 和开普勒（32和64位版本））
- 平台： Windows ， Ubuntu ， Mac
- m2e版本： 1.1.0.20120530-0009 ， 1.2.0.20120903-1050 ， 1.3.0.20130129-0926 ，
1.4.0.20130601-0317
- Regarding Eclipse IDE (Indigo, Juno and Kepler (32 and 64 bit versions))
- Platforms: Windows, Ubuntu, Mac
- m2e version: 1.1.0.20120530-0009, 1.2.0.20120903-1050, 1.3.0.20130129-0926,
1.4.0.20130601-0317
将m2e更新为1.1后，出现上述错误。 通过删除m2e 1.1并回滚到m2e 1.0，一切正常。 我试图重复Windows和Ubuntu中的问题，它给了我完全相同的错误。测试了slf4j-api和logback的大量配置，但似乎没有效果。
The above error came after updating the m2e to version 1.1. By removing m2e 1.1 and rolling back to m2e 1.0 everything worked fine. I tried to repeat the problem in Windows and Ubuntu and it gave me the exact same error. Numerous configurations of the slf4j-api and logback were tested but none seem to work.
即使没有声明slf4j依赖关系，任何maven项目都会出现该错误。
The error appears in any maven project even without declaring slf4j dependency.
-
新的Maven项目 - > maven-archetype-quickstart
New Maven Project--> maven-archetype-quickstart
和
新的Maven项目 - >没有原型选择的简单项目
New Maven Project--> Simple project without archetype selection
结果为
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
测试环境和配置
在Mac上使用Eclipse Indigo和Eclipse Juno（32位和64位）测试，Ubuntu为32位，Windows上为64位和32位。测试新安装的 Juno Classic ， Juno建模工具，开普勒标准，开普勒建模工具并产生了相同的错误。
Testing enviroments and configurations
Tested with Eclipse Indigo and Eclipse Juno (32 and 64 bit both) on Mac, 32 bit on Ubuntu and 64 and 32 bit on Windows. Tested fresh installs of Juno Classic, Juno Modelling tools, Kepler Standard, Kepler Modelling Tools and produced the same error.
出现清洁，安装，测试，部署，生成源，验证，编译， / strong>，验证和目标清除与其余目标的组合。它也出现在参数 -e 和 -X 之间。试图删除m2e仓库并从头开始下载但是再次没有成功。我应该提到它已经在3种不同的机器和虚拟盒子上测试了所有上述系统，但它产生了相同的错误。
The error appears with clean, install, test, deploy, generate-sources, validate , compile , package, integration-test, verify and combinations of the goal clean with the rest goals. It appears also with parameters -e and -X. There was an attempt to delete the m2e repository and download it from scratch but again without success. It should me mentioned that it was tested in 3 different machines and virtual box all the above systems but it produced the same error.
尝试解决 slf4j-api 的所有不同的 logback 配置（从1.0.4到1.0.13）和 logback-core 依赖关系，但都产生相同的错误：
Tried all different logback configurations (from 1.0.4 to 1.0.13) that resolve the slf4j-api and logback-core dependencies, but all produce the same error:

推荐答案
我也可以确认此错误。
I can also confirm this error.
解决方法是在m2eclipse中使用 external maven ，而不是嵌入maven。
Workaround: is to use external maven inside m2eclipse, instead of it's embedded maven.
这是在三个步骤中完成的：
1 在本地机器上安装maven （测试机是Ubuntu 10.10）
1 Install maven on local machine (the test-machine was Ubuntu 10.10)
mvn --version
mvn --version

3 in m2eclipse：从嵌入的maven 切换到本地maven
3 inside m2eclipse: switch from embedded maven to local maven
- 找出本地maven家庭安装目录的地方（google为您的
MAVEN_HOME，对于我来说，这帮助我，这是/ usr / share / maven2 窗口 - >首选项 - > Maven->安装 - >输入该字符串中的
- 。那么你应该已经切换到你的新的外部maven。
- 然后运行你的项目，例如。 maven测试。
- find out where local maven home installation dir is (google for your
MAVEN_HOME, for me this helped me that is/usr/share/maven2) - in eclipse Menu->Window->Preferences->Maven->Installation-> enter that string. Then you should have switched to your new external maven.
- then run your Project as e.g. "maven test".
错误消息应该消失。
