如何在CLASSPATH中使用google-collections在终端中使用javac编译代码？

尝试在终端中使用javac进行编译的代码示例（在Eclipse中运行）

import com.google.common.collect.BiMap;
import com.google.common.collect.HashBiMap;
public class Locate {
   ...
   BiMap<MyFile, Integer> rankingToResult = HashBiMap.create();
   ...
}

在终端中进行编译

src 288 % javac Locate.java 
Locate.java:14: package com.google.common.collect does not exist
import com.google.common.collect.BiMap;
                                ^
Locate.java:15: package com.google.common.collect does not exist
import com.google.common.collect.HashBiMap;
                                ^
Locate.java:153: cannot find symbol
symbol  : class BiMap
location: class Locate
        BiMap<MyFile, Integer> rankingToResult = HashBiMap.create();
        ^
Locate.java:153: cannot find symbol
symbol  : variable HashBiMap
location: class Locate
        BiMap<MyFile, Integer> rankingToResult = HashBiMap.create();
                                                 ^

我的CLASSPATH

src 289 % echo $CLASSPATH 
/u/1/bin/javaLibraries/google-collect-1.0.jar

Answer 1

  javac -cp /u/1/bin/javaLibraries/google-collect-1.0.jar Locate.java

或者，Java 6中的新功能，让它扫描目录

  javac -cp '/u/1/bin/javaLibraries/*' Locate.java

在CLASSPATH中具有Jar的终端中编译Java代码
