java - java -cp "*"是什么意思？

Question

我正在 Windows 上开发斯坦福情感分类器。我想重新训练我自己的模型，网站上是这样指定的:

java -mx8g edu.stanford.nlp.sentiment.SentimentTraining -numHid 25 -trainPath train.txt -devPath dev.txt -train -model model.ser.gz

但这给了我错误:

could not find or load main class

但是将其更改为 java -cp "*" 后它就起作用了。

Answer 1

Class path entries can contain the basename wildcard character , which is considered equivalent to specifying a list of all the files in the directory with the extension .jar or .JAR. For example, the class path entry foo/ specifies all JAR files in the directory named foo. A classpath entry consisting simply of * expands to a list of all the jar files in the current directory.
