如何编译java代码？ [英] How to compile java code?

问题描述

 
我有一堆java文件，我正在运行以下代码来尝试编译它们。 \\Program Files\Java\jdk1.6.0_16\bin\javacMain.java 
  

我正在看到此错误消息

  Main.java:3：package colourtiler.patternsdoes不存在
 import colourtiler.patterns.draw; 
  

它所代表的代码位于文件夹patters / PatternColour.java中，包含此文件？

感谢

解决方案

它在javac / java的 -cp 或 -classpath 参数中的路径。例如

  javac -cp。; c：/ path / to / colourtiler / patterns / draw Main.java 
  

其中 c：/ path / to / colourtiler / patterns / draw 指向依赖关系类的包根。如果你有更多，那么你需要用分号分隔它。如果路径中有空格，则需要引用单个路径。或者，您也可以将它包装在JAR文件中（或使用已打包的文件），并将完整的文件路径放在类路径中的JAR文件中。

输入类路径会感到无聊，请考虑使用批处理/ shell文件。

祝你好运。

I have a bunch of java files and I am running the following code in an attempt to compile them.

"\Program Files\Java\jdk1.6.0_16\bin\javac" Main.java

And I am being shown this error message

Main.java:3: package colourtiler.patternsdoes not exist 
import colourtiler.patterns.draw;

The code it isreferring to is located in the folder patters/PatternColour.java, how can I get it to include this file?

thanks

解决方案

You need to include its path in the javac/java's -cp or -classpath argument. E.g.

javac -cp .;c:/path/to/colourtiler/patterns/draw Main.java

where c:/path/to/colourtiler/patterns/draw points to the package root of the dependency classes. If you have more, then you need to separate it by semicolon. If there are spaces in path, you need to quote the individual path. Alternatively you can also package it in a JAR file (or use an already packed one) and put the full file path to the JAR file in the classpath.

If gathering and typing the classpath get bored, consider using a batch/shell file.

Good luck.
