我知道的唯一方法是单独做，例如:

setenv CLASSPATH /User/username/newfolder/jarfile.jar:jarfile2.jar:jarfile3.jar:.

希望有帮助!

我在Ubuntu 10.04上使用java-sun 1.6.0_24的解决方案，所有的jar都在“lib”目录下:

java -cp .:lib/* my.main.Class

如果失败，下面的命令应该起作用(打印出所有*。lib目录中的jar到类路径参数)

java -cp $(for i in lib/*.jar ; do echo -n $i: ; done). my.main.Class

正确的:

java -classpath "lib/*:." my.package.Program

不正确的:

java -classpath "lib/a*.jar:." my.package.Program
java -classpath "lib/a*:."     my.package.Program
java -classpath "lib/*.jar:."  my.package.Program
java -classpath  lib/*:.       my.package.Program

对于windows，引号是必需的，并且;应作为分离器使用。例如:

java -cp "target\\*;target\\dependency\\*" my.package.Main

简单回答:java -classpath lib/*:。my.package.Program

Oracle提供了关于在Java 6和Java 7的类路径中使用通配符的文档，在“理解类路径通配符”一节中。(在我写这篇文章的时候，这两页的内容是一样的。)以下是此次会议的重点总结:

In general, to include all of the JARs in a given directory, you can use the wildcard * (not *.jar). The wildcard only matches JARs, not class files; to get all classes in a directory, just end the classpath entry at the directory name. The above two options can be combined to include all JAR and class files in a directory, and the usual classpath precedence rules apply. E.g. -cp /classes;/jars/* The wildcard will not search for JARs in subdirectories. The above bullet points are true if you use the CLASSPATH system property or the -cp or -classpath command line flags. However, if you use the Class-Path JAR manifest header (as you might do with an ant build file), wildcards will not be honored.

是的，我的第一个链接与得分最高的答案中提供的链接相同(我没有希望超越它)，但这个答案并没有提供更多的解释。由于现在Stack Overflow不鼓励这种行为，我想我应该对此进行扩展。

java命令的参数顺序也很重要:

c:\projects\CloudMirror>java Javaside -cp "jna-5.6.0.jar;.\"
Error: Unable to initialize main class Javaside
Caused by: java.lang.NoClassDefFoundError: com/sun/jna/Callback

与

c:\projects\CloudMirror>java -cp "jna-5.6.0.jar;.\" Javaside
Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable
