问题描述

我可以使用以下设置在cygwin + windows中运行java(sw / jar目录有几个jar文件,我从java命令行中选择相关的文件):

I can run java in cygwin+windows using the following settings (the sw/jar directory has several jar files, and I pick the relevant one from the java command line):

CLASSPATH=.;C:\sw\java_6u35\lib\\*;C:\sw\jar\\*
java org.antlr.Tool Calc.g

但是我在linux下运行时遇到以下问题:

But I am having the following problems when running in linux:

(1)我无法在类路径中设置目录名,以下行报告错误:

(1) I can't set a directory name in a classpath, the following line reports an error:

setenv CLASSPATH .:/sw/jdk1.6.0_35/lib/\*:/sw/jar/*

(2)当我用-jar选项显式运行时,我仍然收到错误:

(2) when I run explictly with -jar option, I still get an error:

java -jar /sw/jar/antlr-3.4.jar org.antlr.Tool Calc.g
error(7):  cannot find or open file: org.antlr.Tool

但是,该类确实存在。当我做 jar tf /sw/jar/antlr-3.4.jar 时,我得到:

However, the class does exist. When I do jar tf /sw/jar/antlr-3.4.jar, I get:

...
org/antlr/Tool.class

所以我的问题是:(a)如何在unix中指定我的jar目录是包含几个jar文件的xxx,以及(2)如何在运行时从这个dir中选择相关的jar?

So my question is: (a) how do I specify in unix that my jar-directory is xxx that contains several jar files, and (2) how do I pick the relevant jar from this dir at runtime?

推荐答案

要直接在java命令中指定目录中的多个jar,请使用此

To specify multiple jars in a directory, directly in the java command, use this


java -cp/ sw / jar / *org.antlr.Tool Calc.g

java -cp "/sw/jar/*" org.antlr.Tool Calc.g

这将包括所有的罐子

如果你想在Unix / Linux系统中设置类路径,请使用这个

If you want to set the classpath in Unix/Linux systems, use this


export CLASSPATH = / sw / jar / a.jar:/sw/jar/b.jar

export CLASSPATH=/sw/jar/a.jar:/sw/jar/b.jar
