【问题描述】：
我是 Java 和 Gate 的新手，所以我将给出我的详细步骤。我正在尝试在我的 java 应用程序中使用 Stanford pos 标记器，但它给了我这个错误：
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
Reading POS tagger model from file:/home/khaled/smartgit/projects/MicroblogsAnnotator/GATE_Developer_8.4.1/plugins/Stanford_CoreNLP/resourcs/english-left3words-distsim.tagger ... done [2.6 sec].
根据另一个问题，我下载了“slf4j-log4j12.jar”并尝试将其包含在我的类路径中。我不确定这是否是添加它的正确方法，但要这样做，我点击了 netbeans
项目->属性->库->添加Jar
现在再次运行它给了我另一个错误：
