Eclipse RCP插件中的多个slf4j绑定 [英] multiple slf4j bindings in Eclipse RCP Plugin

问题描述

我有一个简单的Eclipse插件，它在激活时出现以下错误：

I have a simple Eclipse Plugin which gives me following error on activation:

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [bundleresource://103.fwk8918249:1/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [bundleresource://103.fwk8918249:4/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

这两个网址都解析为捆绑中完全相同的jar

both URLs resolve to the exact same jar in the bundle

libs/slf4j-log4j12.jar!/org/slf4j/impl/StaticLoggerBinder.class

• 我该如何解决这个问题？


• 为什么捆绑包加载罐子两次（：1）和：4）？



推荐答案

这是定义SLF4J绑定的结果您的项目的类路径（JDT .classpath文件）和MANIFEST.MF文件。

This is a result of defining an SLF4J binding in both your project's classpath (JDT .classpath file) and your MANIFEST.MF file.

您应该从项目的类路径中删除SLF4J绑定：

You should remove your SLF4J binding from your project's class path:




YourProject→属性→ Java Build Path→库

YourProject → Properties → Java Build Path → Libraries



• 选择SLF4J绑定JAR并点击删除。



一旦你这样做，你的类加载器中只应该有一个对SLF4J绑定的引用（因此不应出现错误信息）。

Once you do this, there should only be a single reference to your SLF4J binding in your class loader (and thus the error message should not appear).
